Background technique

At present, the production process of machines refers to the entire process of making products from raw materials (or semi-finished products). For machine production, it includes the transportation and storage of raw materials, production preparation, blank manufacturing, parts processing and heat treatment, product assembly and debugging, painting and packaging, etc. The content of the production process is very extensive. Modern enterprises use the principles and methods of systems engineering to organize and guide production, and regard the production process as a production system with input and output.

The most important step in mechanical processing is to position the parts that need to be processed. Plate-shaped parts are the most common on the market. The two sides of the plate-shaped parts are usually clamped and processed by clamps, and the clamping process requires time to consider.
