CNC Machining, short for Computer Numerical Control machining, is a widely adopted
manufacturing process utilizing automated, high-speed cutting tools to shape metal or plastic
stock into desired designs.
The standard CNC machine types encompass 3-axis, 4-axis, and 5-axis milling machines, lathes,
and routers. The method of cutting CNC parts can vary, with options such as keeping the
workpiece stationary while the tool moves, holding the tool in place while the workpiece rotates
and moves, or simultaneous movement of both the cutting tool and workpiece.
Experienced machinists operate CNC machines by creating tool paths based on the final part's
geometry, which is derived from a CAD (Computer-Aided Design) model. CNC machines exhibit
exceptional precision and repeatability, capable of cutting nearly any metal alloy and rigid plastic.
This versatility makes custom machined parts suitable for various industries, including aerospace,
medical, robotics, electronics, and industrial applications.
