Cnc Machining Development Background

Numerical control technology originated in the needs of the aviation industry, in the late 1940 s, a U.S. helicopter company is put forward.

Machining process

Numerical control machine tool of the initial idea, in 1952 the United States at the Massachusetts institute of technology to develop three coordinate nc milling machine. 50 s the numerical control milling machine has been used in aircraft parts. 60 s, the numerical control system and programming work is becoming more and more mature and perfect, nc machine tools have been used in various industries, but the aerospace industry has always been the biggest users of CNC machine tools. Some of the biggest aviation factory is equipped with hundreds of nc machine tools, which is given priority to with cutting machine. Nc machining of aircraft and rocket parts have a whole wall plate, girders, skin, bulkhead, propeller, and aircraft engine casing, shaft, disc, leaf mold cavity and the surface of the liquid rocket engine combustion chamber of the cavity, etc. Nc machine tools based on continuous path in the early years of the development of nc machine tools is given priority to, continuous path control.

Continuous path control is also called the contour control, request tool relative to the parts in accordance with the provisions, trajectory. After developing point control of CNC machine tools. Position control is refers to the cutting tool moves from one point to another point, as long as the final target accurately and regardless of the mobile route.
