For machine production, it includes the transportation and preservation of raw materials, production preparation, blank manufacturing, parts processing and heat treatment, product assembly, commissioning, oil paint and packaging. The content of production process is very extensive. Modern enterprises use the principles and methods of system engineering to organize and guide production, and regard the production process as a law.

Determine the processing sequence of each surface and the number of processes in the whole process. The formulation of process route must follow certain principles. When the machining plant processes mechanical parts, when the workpiece is too high, it shall be roughened with knives of different lengths in layers. After roughening with a large knife, the remaining materials shall be removed with a small knife. The flat bottom knife is used to process the plane, and the ball knife is used less, so as to reduce the processing time.

In the process of production, large-scale machining changes the shape, size, position and nature of its production object.

It is the main part of the production process. The process can be divided into casting, forging, stamping, welding, machining and assembly. The mechanical manufacturing process generally refers to the machining process of parts.
