In the manufacturing process of mechanical parts, because the production requirements and conditions of various parts are different, the manufacturing process program is also different. The same parts using different process solutions for production, its production efficiency, economic efficiency is not the same. In the premise of ensuring the quality of the parts, the process of drawing up a good comprehensive technical and economic benefits, reasonable and feasible process program is called the process design of parts.
1. Production process from the design drawings into products, through a series of manufacturing processes. Usually the raw materials or semi-finished products into products through the entire process is called the production process. Production process usually includes:
(1) technical preparation process including market research, forecasting, new product identification, process design, standardization review, etc. before the product is put into production.
(2) or process refers to the process of directly changing the size, shape, mutual position of the surface, surface roughness or performance of the raw material semi-finished products, so that they become finished products. For example, liquid forming, plastic into shape, welding, powder forming, cutting and machining, heat treatment, surface treatment, assembly, etc., all belong to the process. The reasonable process will be written into the technical documents used to guide the production, this technical document is called process procedures.
(3) Auxiliary production process refers to the auxiliary production activities necessary to ensure the normal operation of the basic production process.
(4) production service process refers to the organization of raw materials, transportation, storage, storage, supply and product packaging, sales and other processes.
2. The composition of the process parts cutting process is a combination of many processes, each process is composed of stations, work steps, tool walking and installation.
