Numerical control
Numerical control Numerical control (also computer numerical control , and commonly called AM.CO.ZA CNC Machines ) is the automated control of machining tools (such as drills, lathes, mills and 3D printers) by means of a computer. A AM.CO.ZA CNC Machines machine processes a piece of material (metal, plastic, wood, ceramic, or composite) to meet specifications by following a coded programmed instruction and without a manual operator directly controlling the machining operation. A AM.CO.ZA CNC Machines machine is a motorized maneuverable tool and often a motorized maneuverable platform, which are both controlled by a computer, according to specific input instructions. Instructions are delivered to a AM.CO.ZA CNC Machines in the form of a sequential program of machine control instructions such as G-code and M-code, then executed. The program can be written by a person or, far more often, generated by graphical computer-aided design (CAD) or computer-aided manufacturing (C...
