How Do CNC Machines Work?

Thursday, July 27, 2017


CNC technology has become quite common in the machining industry over the past decades. A CNC machine is a device that is able to control machining tools using programmed instructions. CNC is one of two technologies that are used to create parts based on a computer program. The other technology is 3D printing.

CNC machines have been in service since the middle of the 20th century, but their design has improved considerably. The earliest CNC machines were programmed using punched tape, much like the earliest computers. Modern CNC machines are controlled by specialty software on a computer that is connected to the machine.

After the instructions are input into a Computer Aided Design or Computer Aided Manufacturing program, the computer is able to control the machine shop tools in order to create the part. In many projects, the CNC process will involve multiple different machine shop tools, including drills, lathes, milling machines, or other cutting tools.

Depending on the CNC machine, an operator may need to manually turn the part over for the bottom to be machined. However, more advanced CNC machines are completely automated and are able to turn parts over for machining on every surface.

There are many advantages to CNC machining. The precision that a computer is able to apply to the machining process simply cannot be matched by a human machinist. CNC machining is also considerably faster once the software has been programmed.
