About CNC Machining
CNC Machining, which stands for Computer Numerical Control Machining was first introduced in the 70′s. It is a subtractive manufacturing process where material is removed to create the final part. As the power of the computer has increased, so has the capabilities and prevalence of CNC manufacturing process. The machining process is completely controlled by computers allowing for quick, accurate, reproducible and amazing parts to be made.
So how does this work? First off, you need to design the part using a CAD or CAM program. There are many out there and some of the more popular ones are, AutoCAD, SolidWorks, Pro-E, Autodesk and new player, Onshape. The design is very important. Remember, the CNC machine has to be able to reach the area in order to remove materials. It is easy to design a part that cannot be made using this process, so keep this in mind as you are creating the part. With the modern machines, more creative methods are being used to make parts and devices that would not have been possible a few years ago.
Now you have the part and ready to have it made. All the hard work is done, now just let the computer bring your creation to life. Right? Not quite. CNC Machining is a generic term for any computer controlled manufacturing equipment. In fact, you can have a CNC Mills, Lathes, Wire EDM, Plasma Cutters and may other machines. Knowing which type of machine to use on your part can be key to not only having the best final product, but also to keep down cost and time necessary to create the part. Skilled machinist are still a key player when looking for a CNC shop. While the computer now replaces some of the manufacturing skill, the machinist will still make a huge difference in the outcome of the final product. Here is a great set of articles that explains work and effort that goes into setting up and running a CNC machine.
