In the late 1940s, the United States began to study numerical control machine tools. In 1952, the first numerical control milling machine was successfully developed by the servo laboratory of the Massachusetts institute of technology (MIT).
The first CNC machining center was first developed by karni terek in 1958. On the basis of numerical control horizontal boring and milling machine, automatic tool changing device is added, which realizes the centralized machining of multiple processes such as milling, drilling, boring, reaming and tapping after the workpiece is clamped once.
This is a major breakthrough in the development of manufacturing technology, marking the beginning of the era of CNC machining in the manufacturing field. Numerical control lathe machining is the foundation of modern manufacturing technology. This invention has epoch-making significance and far-reaching influence on manufacturing industry. The main industrialized countries in the world attach great importance to the research and development of numerical control lathe machining technology.
CNC machining refers to the process of machining parts on CNC machine tools. Numerical control machine tool is a kind of machine tool which is controlled by computer.
The movement and auxiliary movement of the CNC machine tool are controlled by the instruction issued by the CNC system, which is programmed by the programmer according to the material of the workpiece, the processing requirements, the characteristics of the machine tool and the instruction format (numerical control language or symbol) specified by the system. Numerical control system according to the program instruction to the servo and other functional parts of the operation interruption or information to control the various movements of the machine.
The machine will stop automatically at the end of the part processing. Any type of numerical control machine, in its numerical control system if not input program instruction, the numerical control machine can not work. The controlled action of the bed basically includes the start and stop of the machine; Start and stop of the spindle, change of rotation direction and rotation speed; Direction, speed and mode of feed motion; Tool selection, length and radius compensation; Tool replacement, coolant on and off.
CNC machining process is generally consistent, but there have been significant changes. A machining method that USES digital information to control the displacement of parts and tools.
CNC machining is an effective way to solve the problems of variable variety of parts, small batch, complex shape, high accuracy and high efficiency. The machining center was originally developed from CNC milling machine.
