The historical development of CNC lathe

Numerical control skills refer to the skills of using digital instructions composed of numbers, words and symbols to complete the operation control of one or more mechanical equipment. Numerical control generally uses a general or special computer to complete the digital program control. Therefore, numerical control is also called computer numerical control, referred to as CNC, and is generally called CNC abroad. The concept of NC is rarely used.
Presentation of data carriers and data operations in binary form. In 1908, a perforated metal foil interchangeable data carrier came out; at the end of the 19th century, a control system that used paper as a data carrier and had auxiliary functions was invented; in 1938, Shannon performed rapid data calculation and transmission at the Massachusetts Institute of Technology, Laid the foundation of modern computers, including computer digital control systems. CNC skills are developed in close combination with machine tool control. In 1952, the first CNC lathe came out, which became an epoch-making event in the history of the world machinery industry and promoted the initiative.
Numerical control skills are also called computer numerical control skills, which are skills that use computers to complete digital program manipulation. This kind of skill uses the computer to carry out the operation sequence logic control function of the equipment’s movement track and peripheral equipment according to the pre-stored control program. Because the computer is used to replace the numerical control device originally composed of hardware logic circuits, the storage, processing, operation, logic discrimination and other control functions of the input operation instructions can be completed by computer software, and the micro instructions generated by the processing are transmitted to The servo drive device drives the motor or hydraulic actuator to drive the equipment.
Traditional mechanical processing is performed by manually operating ordinary machine tools. During the processing, the mechanical tool is swayed by hand to cut the metal, and the accuracy of the product is measured with a caliper and other tools by the eyes. Modern industry has long used computerized digitally controlled machine tools to perform operations, and CNC lathes can actively process any products and parts directly according to the programs pre-programmed by skilled personnel. This is what we call CNC machining. CNC machining is widely used in any category of all mechanical processing, it is also the development trend of mold processing and important and necessary skills.
