Though you will need more people without the CNC technology, you will need only three very, very skilled people. Call these people your friends, your team, whatever. In the long run, they might be just all you need to keep the shop in good shape.

THE PROGRAMMER

The first person is the CNC programmer. S/he is like the “playmaker”. S/he will create the programs that the CNC machines are intended to execute. Since the programs are in the form of CNC codes fabricated like sentences, he should have mastered these codes because they work like a different language. The regular CNC machine can use up to 50 codes, so that’s like learning 50 new words for the newbie.

Also, the programmer should have at least and engineering or machining degree. Remember that the CNC machine will only execute WHAT IT IS PROGRAMMED TO DO. If the program is wrong, the whole operation goes down the drain with it. Moreover,s/he should also be flexible and have a fast turn-around because a CNC machine is often used to machine a huge selection of different work-pieces.

THE OPERATOR

Hopefully the information presented so far has been applicable. You might also want to consider the following:

The second person that you need is the CNC operator. S/he will simply recheck the programs loaded to the machine and push the right buttons to get the work done. However, thinking that a CNC operator can have little or NO SKILL AT ALL is wrong. A CNC machine operator must have at least basic machining skills and s/he should have undergone some form of training to run a CNC machine.

These machines can produce very intricate motions, making it possible to make shapes that cannot be created on conventional machine tools. So, the operator should foresee this complexity and know how to cruise with it. The skills that an operator must have though, are lesser compared to the operators of conventional machine tools.

THE TECHNICIAN

The third person that will need is the CNC technician. Although this may still be the programmer, it’s more convenient to always have a technical expert on-call because in the long run, you may have more than one CNC machine and you may need to prioritize over the other in case both gets crippled at the same time. Just like the programmer, the technician should also be flexible and articulate. CNC offers a lot of complexity when it’s running right, how much more if it’s behaving badly?

So, if you are having job openings for positions that need to be handling a CNC machine, ask the applicants first to do a demo for you and make sure that during the demo, they know what they’re doing. An exam may also do wonders too. If they have no experience with any kind of CNC machine, it is advisable that you encourage them to take short courses on CNC.

Eighty-hour courses are available online and hey, it’s better than nothing. Experts even encourage employers to hire CNC machinists who have finished AND PASSED the National Occupational Competency Testing Institute (NOCTI) assessment just so they could be sure that their CNC machines will go to good hands. After all, a CNC machine is still an asset.

There’s no doubt that the topic of CNC can be fascinating. If you still have unanswered questions about CNC, you may find what you’re looking for in the next article.

Pad printing is a process where a 2-D object is transferred into a 3-D object. It is done by using an indirect offset printing process that involves an image being transferred from the printing plate via silicone pad over a surface that is to be printed.

Pad printing is used on a lot of industries that includes medical, automotive, promotional, apparel, electronics, appliances, sport equipment and toys. Pads are three dimensional objects typically molded of silicone rubber. They function as a transfer vehicle that picks up ink from the printing plate, and then transferring to the thing to be printed upon.

Examples of pad printing are the printing of labels on the keys on a keyboard or the logo of a toy manufacturer on a Frisbee. The unique properties of a silicone pad allow it to pick the image up in a variety of surfaces such as a flat, cylindrical, spherical, compound angle, textures, concave surfaces or a convex surface.

In presses that uses pad printing with Computer Numeric Control (CNC), the substrate or a material that can be printed on, such as paper, film, plastic, fabric, cellophane, or steel, is stationary and the silicone pads are programmed to print one image at a time.

With a press that uses Computer Numeric Control, the substrate is stationary and the pads are all programmed to one image at a time to achieve a multicolor print.

Think about what you’ve read so far. Does it reinforce what you already know about CNC? Or was there something completely new? What about the remaining paragraphs?

Though the robotic actions of these presses that uses Computer Numeric Control seems rather complicated, it allows simple setting procedures that enable several programs to be inputted into the machine. All actions are controlled by servo-motor drives giving a very smooth and highly controllable printing action, also giving stroke lengths to be infinitely variable to the dimensions of the machine. Manufacturers even claim that using presses with pad printing capability that uses Computer Numeric Control gives considerable energy savings to the industry.

The Computer Numeric system of control can be built on standard machines or modular assemblies that can be produced to suit any application. The degree of complexity is regulated only by the imagination of the designer of the product/s and the number of modules he wishes to use to complete his desired quota.

All of the elements of component manipulation can be achieved by combining with multiple closed cups, pad cleaning, varying pad-stroke lengths, alternative pad shapes and a lot more. This type of system is often used where items must be printed in line with other assembly processes, or for complex multiple prints on different surfaces.

The flexibility of a Computer Numeric Controlled press comes close to producing the ideal machine for a particular application. Although a CNC press is substantially more expensive than that of a conventional pneumatic press. If the workload can justify the use of a CNC press for the increase in investment, then the CNC press is well worth considering.

Although it is wise to not be carried away by the current technology at hand, it still must be a capable printer.

Motion control can be applied in many categories such as robotics, CNC operated machine tools and Kinematics, wherein motion control in kinematics are usually simpler. It can be mainly used nowadays with packaging, textile, assembly industries, printing, and semiconductor production. The hardware of a motion controlled machine usually consists of drive systems, motors, a computer, a PLC or Programmable Logic Controller to run the programs, and an amplifier.

The basic design of a motion control system would include a motion controller to produce a set of points including closing a position, a drive or amplifier to convert the control signal of the motion controller into a high power electrical current, an actuator, one or more feedback sensors, and mechanical components to convert the motion of the actuators to the desired motion.

CNC machines use programmable commands to make inputting motion to the machine easier rather than using cranks or other conventional machine tools. Almost all CNC machine tools can have programmable motion type (whether it would be rapid, linear or circular), the amount of motion, the feedback rate, and the axes to move.

Motion control is the simplest function of any Computer Numerical Control (CNC) machine. It is precise, consistent, and automatic system of control. CNC equipments need two or more modes of direction to which they are called axes. There are two common axis types and they are called linear and rotary. The linear axis type of motion control is driven along a straight path while the rotary axis type is driven along a circular path.

The operator of the motion controlled machine counting the number of revolutions made on the handwheel, added the generations of the dial would accomplish accurate positioning. The drive motor of the machine would be rotated to a resulting amount, which would then drive the ball screw, which would cause the linear motion of the axis. The feedback device at the end of the ball screw would confirm its revolutions.

The best time to learn about CNC is before you’re in the thick of things. Wise readers will keep reading to earn some valuable CNC experience while it’s still free.

The same linear motion can be found on a table vise. When you rotate the vise crank, it would also rotate a lead screw, which would then be able to drive the movable jaw in the table vise. In comparison to a motor controlled CNC machine, the linear axis in it is extremely precise compared to that of a table vise. This is because the number of revolutions of the axis drive motor in the CNC machine accurately controls the amount of linear motion along the axis.

A CNC command programmed and executed within a control of a machine would tell the drive motor of the machine as to how many number of precise times it would rotate. This in turn would rotate the ball screw then the ball screw would drive the linear axis. After the process has started, a feedback device located at the end of the ball screw would confirm the programmed number of rotations that the machine would run has taken in effect.

How would axis motion be controlled?

Utilizing a form of coordinate system would make axis controlling a whole lot simpler and more logical to the CNC control. Two coordinate systems that are being used in CNC machines that have been popular are rectangular and polar coordinate system, to which the more popular of the two is the rectangular coordinate system.

Graphing is a common application for the rectangular coordinate system and is needed to cause movement in a CNC machine.

You can’t predict when knowing something extra about CNC will come in handy. If you learned anything new about CNC in this article, you should file the article where you can find it again.

You might have not heard of the CNC before, or what it does, or how it makes lofty manufacturing operations a lot easier. However, CNC machining is dubbed as one of the most important factors of most production processes. The common tasks CNCs machines usually perform are drilling holes, tool changing, cooling and lubrication of separate factory machines at the same time.

Let’s start with a brief introduction. CNC stands for Computer Numerical Control and it has been around since the early 1970’s. Before it was christened CNC, it was called NC, for Numerical Control. When computers were introduced during 1070’s, the name changed. It has stroked almost all manufacturing forms in almost all stages of production. CNC machines either substitute some existing manufacturing processes or combine work with them.

A CNC program is just any other set of instructions. It’s written like a sentence and the order of operation is chronological. The machine will then execute that set of instructions step-by-step. A special series of CNC words/codes are used to relay what the machine is supposed to do. CNC codes begin with letter addresses (like S for spindle speed, and X, Y & Z for common linear axis motions).

When certain codes are arranged together in a coherent method, this group of CNC codes create a ?command? that is like a sentence. A common CNC machine will only be needing around 40-50 words/codes to program different commands. See, it’s not very difficult to learn.

Although CNC sounds very independent and do-it-all, there are a few words that you need to know to fully understand CNC operations.

THE CAM

Sometimes the most important aspects of a subject are not immediately obvious. Keep reading to get the complete picture.

CAM stands for Computer Aided Manufacturing. It simplifies the programming processes which are new, and added to the CNC program regularly. Of course, the easy applications can be programmed with only the simplest machines around: the pen, paper and calculator. However, more complex programs are vital regularly. It is when composing these programs become much more tricky and (worse) tedious.

The CAM is a program that runs on a computer that aids the CNC programmer with the programming. It also works hand-in-hand with the CAD (Computer Aided Design) design drawing (those designs engineers compose/nurture). With the CAM helping, redefinition of the work-piece configuration is not needed. What the CNC programmer is left to do is just to specify the machine operations to be executed and the CAM system will compose the CNC program automatically. Thanks to CAM, programming tediousness will not be a problem to the CNC programmer again.

THE DNC SYSTEM

DNC stands for Distributive Numerical Control. It is a computer that is connected with one or more CNC machines, forming a network. When a program is manually composed and ready to be loaded to the CNC control, it is being typed right into the control. However, this is like using the CNC machine as a luxurious keyboard.

Moreover, if the CNC program is achieved with the help of CAM, it is already in text form and ready to be loaded to the CNC control. The DNC simply distributes the CNC program to more than one CNC machine. Lately, the newest controls are more advanced in terms of networking capabilities and can be networked with, say, the Ethernet.

If it’s your first time to read and learn about the CNC, it may sound so mighty and ubiquitous. It’s about time you learn they also need help from some programming friends such as the CAM and the DNC. No man is an island; but hey, neither are CNC machines.

As your knowledge about CNC continues to grow, you will begin to see how CNC fits into the overall scheme of things. Knowing how something relates to the rest of the world is important too.

The Punch press

An example of a CNC machine that is used in sheet metal manipulation is the punch press. This device uses hydraulic, pneumatic, or electrical power to exert immense pressure to shape the metal and cut it according to the designs. Being computer aided, this machine is capable of rapid positioning and therefore, fast production. Manual punch presses compromise speed for accuracy therefore lessening efficiency.

The punch press works by receiving instructions from a program in a computer. This allows the operator to sit back and relax once the cycle (rapid positioning, punching, and switching of tools) has been initiated. These machines perform operations with accuracy that is measured by the thousandth of an inch.

Introduction of these machines into the sheet metal industry sped up production significantly. And to stay competitive in the global market, such an edge would be needed. However, technology finds ways to improve on this.

New devices

Today, presses have newer versions. The turret punch press is capable of sorting sheet metal into their respective design classes. This means that the new punch presses can operate virtually unattended. Steel manufacturing companies invest in these machines should it mean streamlining of their jobs and increasing production capabilities.

Once you begin to move beyond basic background information, you begin to realize that there’s more to CNC than you may have first thought.

Newer CNC machines can even alert operators who are not in the area if a problem crops up during the sheet metal punching process. This happens by enabling the CNC machine to keep track of the operators’ phones. Therefore, the workload of the operator is relaxed to the point that he/she does not even need to be in the area of operation.

The drawback

However, these machines do not come cheap. A lot of time, money, and effort have to be spent in order to operate the machine to its fullest capacity. Furthermore, there is a shortage of people who are skilled enough to operate such machines. An operator has to be knowledgeable with BASIC programming language, fundamental machining processes, design awareness, and accessory functions.

Furthermore, knowledge of Computer Aided Design and Computer Aided Manufacturing (CAD/CAM) is a big factor in being able to control such machinery. So the capital that you have to spend on understanding these machines have to be justified with the caliber of the operator that you have.

Another drawback that is present is the compatibility of the machines with the current technology that the company has. If they are incompatible, it takes even more time and money to replace current facilities or to restructure the factory in order t accommodate such devices.

The Conclusion

so, if you’re a big company and you want to stay in the race, you have to consider and reconsider investing into these things. The investment may be worth itself a hundred times over but it is a rather risky choice to step into something new. You have to restructure your work schedules, change the requirements for operators, and provide proper training to operators that you want to keep.

These things will cost a lot and will take a while before they reflect what they really are worth.

This article’s coverage of the information is as complete as it can be today. But you should always leave open the possibility that future research could uncover new facts.

Cycle time is defined to be the time that happens from the time a task or series of tasks is initiated to the time a task is completed. Example, the cycle time is the time a shipping order is printed to the time it is loaded on the truck and the system is updated. An alternate definition would be is the time it takes to load, run, and unload on workpiece.

Cycle time of a machine can be simply measured by timing how long it takes from pressing the button to start the cycle for the first workpiece to the pressing the next button for the next workpiece.

Production quantities in an industry dictate that the more workpieces you run, the more important it is to achieve the goal of lowering the cycle time.

Everything and anything that happens in a Computer Numerical Control (CNC) machining equipment can be divided into four categories:

1.) On-line, productive tasks:

These are the actual machining operations that occur during a CNC cycle. These are the milling, drilling, tapping, reaming, and any other machining operation that in some way furthers the completion of the workpiece. To minimize the cycle time in these areas, there are two ways in which this can be achieved. One would be through careful process planning.

The process engineer must select an appropriate machine tool, cutting tools, fixturing, and machining order in a way that it matches the number of workpieces to be machined that will be based on the production quantity. The cycle time will be a reflection of the processes being used to machine workpieces.

The information about CNC presented here will do one of two things: either it will reinforce what you know about CNC or it will teach you something new. Both are good outcomes.

If in the many times that your company’s processes have already been developed and implemented before you begin your cycle time reduction program, then your second alternative is to optimize cutting operations for this would involve properly selecting cutting tool materials, feeds, and speeds to machine workpieces as efficiently as possible with the current process.

2.) On-line, non-productive tasks:

These are tasks that occur during the machining cycle that do not actually further the completion of the workpiece. The first thing Computer Numerical Control people often target for improvement is wasted program execution time. These are the things like rapid movements, tool changes, M-code execution and spindle acceleration/deceleration. Reducing program execution time in this area is usually easy.

It often takes nothing more than carefully monitoring the production run for a few workpieces to find those times when the program can be modified to eliminate noticeable pauses during the cycle. Although keep in mind that the worker for these machines must not overlook other processes for they may be so concerned with minimizing program execution that they overlook other operations, resulting in severe wastes of cycle time.

3.) Off-line, non-productive tasks:

These are the tasks performed in the machining cycle that do nothing to further the completion of the workpiece. Since these types of tasks are done while the machine is producing workpieces, they do not actually add to the cycle time. It is possible to free the operator of the machines of performing off-line productive tasks if they have little, or nothing to do during lengthy machine cycles.

4.) Off-line, productive tasks:

These are the tasks done away by the CNC machine, while the machine is producing workpieces, which would further the completion of the workpiece. This is extremely helpful during lengthy CNC cycles, tasks in this category can reduce the time it takes to complete the production run dramatically, which would effectively reduce cycle time.

HOW TO PROGRAM A CNC MACHINE

CNC programming uses a code similar in structure to BASIC. So, if you know how to construct a simple counting program, chances are, you already know what a G-Code looks like. However, there a few other things you have to consider before you start encoding instructions.

The first thing that you have to do is to assign values for each of the variables. These variables include the programmable motion directions (axes), and the reference point for the axes. The values that you assign to these variables dictate the movement of the machine.

The next thing that you have to do is to take into account the accessories of the machine. Many machines have accessories that are designed to enhance the capabilities of the basic device. However, using these accessories requires you to include them in the coding system. This means that if you want a more efficient machine, you will have to know the machine inside out.

READING CODES

After those steps, you have to create a subprogram that will deal with the math. This step will then allow your machine to compute the necessary variables and effectively operate without stopping to ask the operator what the limitations are.

The best time to learn about CNC is before you’re in the thick of things. Wise readers will keep reading to earn some valuable CNC experience while it’s still free.

To show you what these codes look like, here’s an example from Wikipedia:

#100=3 (bolt circle radius)
#101=10 (how many holes)
#102=0 (x position of ctr of bolthole)
#103=0 (y position of ctr of bolthole)
#104=0 (angle of first hole
Tool call,
spindle speed,and offset pickup,etc
G43 in some cases (tool length pickup)
G81(drill cycle)
call sub program
N50
G80
M30

Subprogram
N100
#105=((COS#104)*#100) (x location)
#106=((SIN#104)*#100) (y location)
x#105 y#106 (remember your G81 code is modal)
If #100 GT 360 goto N50
#100=(#100+(360/#101))
Goto 100

In the code above, the machine is a drill. The operator utilized a loop in order to keep the machine from stopping. The subprogram then governs the cycle of the machine. This code is still quite a simple code. Other machines require the inclusion of the maximum RPM in the coding.

An easier way of programming CNC machines would be the use of Computer Aided Manufacturing (CAM). This system takes on the brunt of programming so that it doesn’t seem so tedious and frustrating. It is still similar to BASIC.

Another programming enhancement that was developed was the parametric programs or the logical commands. These programs were designed to shorten lengthy codes in order to make them user friendly. However, these codes do not always use the same language with every machine. The language and sequence often varies depending on the typ of machine you will be working on.

The operator has to know what the machine can do or what it was made to do before attempting to program it. You should be able to visualize the machine doing what you want it to do.

But, you don’t have to be a math wizard or a programming genius. You just have to know what your machine does and what you want it to do.

There’s no doubt that the topic of CNC can be fascinating. If you still have unanswered questions about CNC, you may find what you’re looking for in the next article.

Since the dawn of the CNC (Computer Numerical Control) machines introduction in the machining sector, they have been praised for being accurate, fast, consistent and flexible. Although CNC machines are not totally independent, a lot of major industries depend on these wonder machines. Common CNC-dependent industries include the metal industry and the woodworking industry. However, these industries, when small-time, can be operated by hands.

In this article, you will learn about the industries which are CNC dependent not because they have grown big in time but because they have to. It can be also that they are CNC dependent because their industries demand a low level of tolerance and a high level of sophistication. There are no ?small-time? members of this industry. Let’s start discussing.

THE AEROSPACE INDUSTRY

First off, this is already a very sophisticated industry. An engineering degree (solely) will not get you anywhere in the Aerospace industry. Not even within striking range. This industry demands so high from their members so machine shops that belong to this industry trust only the best of the best of CNC machining. In fact, sources say that the term ?Precision Machining? has been coined from this industry.

In the materials they use, the aerospace industry already demands a lot. CNC machines which are used here are mostly capable of handling Inconel, Titanium, Magnesium, Stainless Steel and so much more. From parts of the landing gear, to shuttle seats, to housings, and even oxygen generation, CNC machines play a big part in their manufacturing.

It’s not just that. Every CNC machine used in this industry also has to be approved AND RATED by the Federal Aviation Administration (FAA) to be safe and to be surely capable of ?Precision Machining?. A NASA experience is highly praised too.

THE MEDICAL INDUSTRY

Knowledge can give you a real advantage. To make sure you’re fully informed about CNC, keep reading.

If the Aerospace Industry demanded precision above all, the Medical Industry demands sterility as much as precision. That’s something that you may have known since you got your first vaccine. Most CNC machines which work for this industry are multi-spindle and contain multi-turret lathes.

These special features allow the company to turn out components for hospital equipment, pulse meters, blood purification systems and mother medical devices. They are also useful in the mass production of disposable items and non-embeddable components.

High-torque milling and turning spindles are heavily demanded in this industry to enable users to process all substrates currently used in the medical device and orthopedic implant markets. Moreover, CNC machines recommended in the medical industry are those which can properly handle Titanium, Cobalt Chromium, Nitinol and others.

THE MILITARY INDUSTRY

This industry’s main concern aside from precision is security. In fact, if you try to search online the CNC-manufactured materials or CNC machines used in this industry, no matter how famous their reputation is, the manufacturer cannot display (pictures of) the materials that they have produced for their clients. They can only display products which they are used in.

This industry deals heavily with Inconel, Titanium, Kevlar, Monel and Hastealloy; so most CNC machines recommended in the Military industry must be able to handle those.

Famous CNC standards evaluators in this industry include the Department of Defense (DOD), the Mil Spec (Military Specifications) and other selected military sectors.

The top managers of these industries also demand their CNC machines to be purchased from CNC machine suppliers which adhere to the International Standards Organization (ISO). And because these industries are CNC-dependent, their shops can occupy a vast amount of space. Basically, that makes no room for old school methods and errors.

That’s the latest from the CNC authorities. Once you’re familiar with these ideas, you’ll be ready to move to the next level.

When a program is completed and sent to the Computer Numerical Control Machine, the programming process is over. All calculations were made and the algorithm fully written. But the question is the programmer’s job really finished? When is the programmer’s responsibility really over? And how can we evaluate the type of program that the Computer Numerical Control Machine programmer did?

The fairest and reasonable answer to those questions would basically when a part has been machined under the most optimized working conditions. Therefore the Programmer’s responsibility does not end after he or she finishes the program. We could say that the program at this stage is still very much in the development process, because most of the programming considerations were based on certain assumptions and there are a lot of external factors that may affect the outcome of the product.

Every Computer Numerical Control programmer should have an effort to be in the touch with the actual production. In the field of software development, Constant communication with your colleagues as well as actual machine operators of the CNC will help you to improve your own program. Because most of the time the CNC machine operators are a good source of constructive ideas, improvements and suggestions.

A good CNC programmer should talk, ask questions to them and most importantly listen to what they have to say. Programmers who never put their foot in the actual machining process and think they are always right are all on the wrong track. Exchanging ideas with CNC machine operators, asking questions and seeking answers is the only way to be fully aware of what is going on in the machine.

Whenever you start a Computer Numerical Control Program the first time it is important to check its Program Integrity. A new and unproved program is a potential source of problems. During Manual Programming in CNC, mistakes are more common than when the program is made in a CAM program.

See how much you can learn about CNC when you take a little time to read a well-researched article? Don’t miss out on the rest of this great information.

A good way to look at a new program is through the machine operator’s perspective. Experienced Machine Operators take a direct approach when running a program for the first time. That means that they wont take any chances of mistakes with the actual running of a program therefore a good programmer must take note of any comments that the Machine operator will say about the program.

What does an experienced Machine Operator look for in a new part of a program? Most of the Machine operators would say that the first and most important thing to be checked on a Computer Numerical Control Program is its consistency. Therefore a machine operator looks at how a CNC programmer does its own programming, is the way you create your own algorithms the same as the other ones. Machine Operators take note with this kind of Information.

Upgrading your CNC Program

Whenever you upgrade your own program, it means that you are strengthening or enriching it, therefore making it better than it was before. Upgrading would be based on this standard, It is to decrease the production cost without compromising the quality of the part being manufactured or the safety of the Computer Numerical Control Machine Operator.

One of the Most Common forms of Program Optimization is doing some minor changes to the spindle as well as the feed rates of the machines. This process is called cycle time optimization, slightly increasing the spindle speed and feed rates of these machines will decrease the time it takes to finish the part.

And when we compare it to mass production, saving one second for each part in a batch of 3600 pieces would mean an hour saved. Efficiency in the rate of production is a very important aspect in Mass Production.

It never hurts to be well-informed with the latest on CNC. Compare what you’ve learned here to future articles so that you can stay alert to changes in the area of CNC.

CNC machine tools are praised all over the world because of three major factors: automation, accuracy and versatility. Human (operator) intervention is reduced to minimal levels because CNC machines can run on its own after it is programmed. Also, when the program is perfected, the CNC machine can run the instructions perfectly on its own.

Remember that any CNC machine can also be programmed to do special one-time tasks such as a dry-run, which will help the operator oversee what will happen when s/he leaves the CNC machine to do its tasks alone. Accuracy also goes hand in hand with repeatability. Again, once the program is perfected, the CNC machine can perform that task PERFECTLY even until 7 or 7000 times.

Lastly, versatility also works in the form of ?task memory? that these CNC machines have. Once a program has been performed even for just one production run, it can be easily recollected the next time that the company needs the program. This saves time for setting up and loading of different programs.

The CNC sure simplifies the work of thousands of factories and machine shops worldwide. However, no matter how great CNC sounds like, it is something that doesn’t fit in some industries. Like, perhaps, in the cosmetic industry, or in the show-business. Those examples are way too obvious. On the other hand, in these two major mechanical industries, CNC is almost synonymous to ?hero?.

THE METAL INDUSTRY

Think of Metal. Metal. Perhaps the easiest metal that you can imagine is that of?a spoon. Now, imagine ANY spoon done with bare hands. After that, imagine a thousand spoons done with bare hands. It’s so tedious you might even consider suicide if you are assigned to such a job.

The metal industry has been operating on CNC for ages. In fact, if you search CNC in the internet, you will instantly find metal companies topping the list. The major CNC centers that you will find in most metal machining processes are ?CNC turning centers?, ?CNC machining centers?, ?CNC grinding centers? and ?CNC drill and tap centers?.

Once you begin to move beyond basic background information, you begin to realize that there’s more to CNC than you may have first thought.

Some of the CNC programs that are connected with the metal industry are milling, drilling, reaming, boring and tapping. Moreover, any metal that has any curved side have experienced some form of knurling, grooving, turning and/or threading.

Fabrication, in manufacturing, refers to processes that are executed on thin plates/sheets. These sheets are cut, punched, and bent to form their finishing shapes. CNC also stars in almost every aspect of metal fabrication.

THE WOODWORKING INDUSTRY

While the most beautiful wood-worked products are most likely hand-made, you cannot deny that a wide array of tools and furniture HAVE to be NOT hand-made to save time and for mass production levels. There’s just too much work and not to many hands. In light with this, CNC has worked wonders for this industry.

Important woodworking processes include cutting, framing, carving and engraving. The most useful woodworking CNC product is the CNC router table. It is capable of carving elaborate 2D and 3D designs. Moreover, it is also capable of material change while repeating the same design. Since contemporary furniture is often a splash of different materials (e.g. Wood, aluminum and/or plastic), any CNC router is capable of reproducing the same design EVEN in different kinds of materials by just altering the router bit.

Although many local, middle-sized enterprise owners are skeptical about using employing CNC in their manufacturing operations, there have been many success stories to sway them to using it anyway. In the Metal and Woodworking industries, CNC has proven itself time and again to be efficient.

It saves time and efforts in production and (more importantly) back-jobs. If you’re venturing to one of these industries, remember that the word “labor” isn’t something social anymore – it’s technological. And start calling CNC your best friend.
