Most mechanical parts made by metal machining must undergo mechanical processing and manufacturing before being installed on mechanical equipment. Mechanical processing is often the production process before the installation of mechanical parts. Therefore, the quality and price of mechanical processing have a significant impact on the quality and cost of most equipment for mechanical parts. In addition, the processing is complex, and there are many commonly used CNC lathes, CNC blades, fixtures, measuring tools, etc. Their characteristics, characteristics, precision, production efficiency, etc. It's different. Some parts require heat treatment and artificial aging during the manufacturing process of parts. Therefore, in the design process, it is important to consider machining.

Metal mechanical processing or specifications are particularly heavy, with high fineness, small specifications, unique application standards, and a particularly large total output. The manufacturing and processing of such unique mechanical parts usually have great uniqueness, which should be taken into account when formulating. Whether a part can be manufactured is likely to become a key factor in design.

For the product structure design of metal machined parts, this article suggests paying special attention to the following issues:
1) Structural design of parts and products that save raw materials.
2) Product structure design reduces the labor of mechanical processing and manufacturing.
3) Reduce manual processing or fill in product structure design for production processing.
4) Simplify the shape and rules of the surface to be produced and processed.
5) The structural design of metal machining products is conducive to clamping measurement.
6) Prevent CNC blades from being at a disadvantage during drilling.
7) Timely handle the structure of shafts and holes (inner and outer layers).
