I. Production process and process.
1, the production process: from the design drawings into products, to go through a series of manufacturing processes. Usually the raw materials or semi-finished products into products after all the process called the production process.
2, the composition of the process: parts of the cutting process is a combination of many processes, each process is composed of stations, work steps, tool walking and installation.
Second, the process of parts.
1, the requirements and steps for the development of process procedures
Process procedures are technical documents to guide the production, process procedures must be economical and reasonable. Parts of the process procedures is the parts of the processing methods and steps.
Content: processing technology (heat treatment process), determine the process used machine tools, clamping methods, measurement methods, machining allowances, cutting amounts and work quotas. The content will be filled in a certain form of card, which is the protocol of machining process, that is, machining process card.
2, the process analysis of the part, its main content:
(1) check whether the drawing of the part is complete and correct, analyze the main table of the part and the accuracy, table and integrity, technical requirements, etc. in the existing production conditions can be achieved.
(2) check whether the selection of the part material is appropriate, whether it will make the process difficult and complex.
(3) Review the structural processability of the part, check whether the structure of the part can be economically and effectively processed out.
3, commonly used process documents are as follows.
(1) machining process card: its main role is to briefly explain the process route of machining.
(2) machining process card: process documentation required to be as detailed and complete as possible, in addition to the process directory, but also each process process card.
