Expanded Information
Numerical control machine tool is the abbreviation of numerical control machine tool (Computer numerical control machine tools), which is a kind of automated machine tool equipped with program control system.
The control system is capable of logically processing a program with a control code or other symbolic instruction, decoding it, and expressing it as a coded number, and inputting it into the numerical control device through an information carrier. Various control signals are issued by the numerical control device after arithmetic processing to control the action of the machine tool, and the parts are processed automatically according to the shape and size required by the drawing.
