CNC machining is a subtractive manufacturing process that employs computerized controls and machine tools to remove layers of material from a stock piece, known as the blank or workpiece, to produce a custom-designed part 1.

In plain English, we explain how the CNC process works, what it stands for, and the different types of CNC machines available.

In short, CNC machining is a metal fabrication method where written code controls the machinery in the manufacturing process. The code determines everything from the movement of the cutting head and the part to spindle speed, RPMs, etc.

CNC machining is a manufacturing technology that works by pulling out material through instructions fed to the machine by a computer called G-code. There are typically two kinds of basic CNC machines you’ll find, one that holds the stock while a rotating tool cuts it and another machine that rotates the stock material while a stationary tool ...

CNC machining is a subtractive manufacturing process that creates parts by selectively removing portions of a workpiece using cutting tools or media. To understand CNC machining, it's essential to first grasp what CNC (Computer Numerical Control) is.
