In people's daily lives, as well as in industrial and agricultural production departments, research institutions, and national defense departments, a large number of various machines, instruments, and tools are used. These machines, instruments, and tools are mostly made of metal parts of a certain shape and size. Metal parts, from blanks to qualified products, generally require mechanical processing. In mechanical processing, various machine tools are used, commonly used being metal cutting machines.
A metal cutting machine tool is a type of machine that uses cutting methods to process metal blanks into machine parts. It is a machine used to manufacture machines, known as "machine tools" or "tool machines", and is commonly referred to as machine tools. Common machine tools include lathes, milling machines, slotting machines, planers, grinders, drilling machines, inspection machines, broaching machines, cutting machines, gear machining machines, thread processing machines, and electric machining machines. With the development of science and technology, Americans invented numerical control and numerical control machine tools in 1952
Digital control is a method of using digital signals to control the motion and machining process of machine tools, and it is also an automatic control technology, abbreviated as CNC (Numerical Control). Using a computer to control machining functions and achieve digital control is called computer numerical control
