Overview: What’s CNC Machining?
What is CNC machining?
CNC machining is a manufacturing technique for removing material. It uses sharp cutting tools, available in a variety of shapes and sizes, which are precisely controlled by a computer. CNC stands for Computer Numerical Control.
How CNC machining works
CNC machining starts with a computer, on which designers prepare a part using CAD (Computer-aided Design) software. This digital part is then converted into a format that can be recognized by a CNC machine.
Instructions are sent to the CNC machine in the form of “G-Code” after which the machine can start cutting.
Most CNC machines have a “worktable” and work holding device to keep a block of material — known as the “workpiece” — in place. The worktable may or may not move, depending on the style of the machine.
When machining starts, the cutting tool makes contact with the workpiece, cutting away layers of material. The tool and/or workpiece is moved and/or rapidly rotated according to the G-Code instructions so that cuts are made in exactly the right places until the part is finished.
Different types of CNC machine
CNC machines include CNC mills, CNC turning machines (or lathes), CNC routers, and Electrical Discharge Machining (EDM) machines.
CNC mills have rotating cutting tools that are moved to different areas of the workpiece to make cuts and can be used to make many different pats. CNC lathes work the other way, rotating the workpiece against a stationary cutting tool, and are used to make cylindrical parts.
CNC routers are similar to CNC mills, but have less power and cannot cut the hardest materials. They can, however, be faster than CNC mills.
EDM uses electrical discharges (sparks) instead of a sharp cutting tool to cut material. No physical contact is made between the tool and the workpiece.
CNC machines are often defined by their number of axes. More axes mean they can move their tool and/or workpiece in a greater number of ways, giving greater cutting flexibility and the ability to make more complex parts in a shorter time.
