Design steps and requirements of precision machining

Precision machining is the whole process of changing the size or characteristics of the product workpiece with processing equipment, which is also non-standard automatic processing. According to the temperature of the processed product workpiece, it can be divided into cold drawing and heat treatment. Generally, it is processed at room temperature without causing organic chemistry or phase transformation of the product workpiece, which is called cold drawing. Generally, processing at a temperature higher or lower than normal will cause organic chemistry or phase transformation of product workpiece, which is called heat treatment. Cold drawing can be divided into drilling and working pressure processing according to the difference of processing methods. What are the design steps and requirements for precision machining? Let's learn about it:

1. A large number of production and manufacturing types;

2. Analyze the process of parts (select national standards);

3. Determine the type, shape, specification and precision of hair germ;

4. Draw up the process route. It is an important step in formulating process procedures. The key work is to select accurate positioning standards, determine the processing method of each surface layer, assign the processing sequence, determine the level of centralization and decentralization of the process flow, and allocate the heat treatment process, detection and other auxiliary process flows. When drawing up the process route, we usually clearly put forward many possible plans, analyze and compare them, and finally determine the best plan;

5. Determine the machine and equipment selected for the process flow.
