The control system can use control codes or other symbolic instructions to logically process and decode the program, so as to make the machine tool move and process parts. English abbreviation CNC, also known as CNC machine tools and CNC lathes, is called computer gong in Hong Kong and Guangdong Pearl River Delta.
In CNC machine tools, the role of the operator is minimized. The operator only needs to input the instruction program into the computer, load the required tools into the machine, and the rest will be done automatically by the computer. The computer instructs the machine tool to perform various machining operations according to the instruction program input by the operator.
Development history of numerical control system
Computer numerical control is a kind of numerical control system, which uses a special computer that can store programs to perform some or all basic numerical control functions. The early CNC system was composed of hardware circuits, which was called HardNC.
After1970s, hardware circuit components were gradually replaced by special computers, which were called computer numerical control systems. Usually, a special computer with an interface circuit is used to control the actions of multiple numerical control devices. So now the numerical control is generally CNC (Computer Numerical Control), and the concept of NC is rarely used again.
