CNC


The sequencing and actuation of the motions on screw machines and chucking machines has traditionally been controlled by cams and other mechanical devices. The modern form of control is CNC in which the machine tool operations are controlled by a ''program of instructions''. CNC provides a more sophisticated and versatile form of control than that of a common mechanical devices. CNC has led to the development of machine tools being capable of more complex machine actions and higher level of automated operation than conventional screw machines and chucking machines.

CNC is an abbreviation for Computer Numerical Control refers to the fact that the machine tools are automatically operated by programs. This is different in comparison to the manual controls of hand wheels and levers or with mechanical cams. CNC has over the past years revolutionized the machining processes, optimizing efficient production.

CNC machines most commonly use designs made by Computer-Aided Design(CAD) and computer-aided manufacturing(CAM). The program processes a computer file that is interpreted to extract commands that are needed. In either way the production of any part is highly automated and produces parts that closely match the designs made in CAD.
