The mechanical finishing process greatly reduces the number of its tooling during operation. The complicated shape of the parts requires no complicated tooling. If the shape and size of the parts are to be changed, only the part processing program needs to be modified, which is suitable for the development and modification of new products. type. The machining quality of mechanical finishing is stable, the machining accuracy is high, and the repeat accuracy is high, and it can meet the processing requirements of the aircraft.
Mechanical finishing process design
1. The designed process specification shall ensure the machining quality of machine parts and meet the technical requirements specified on the design drawings.
2. The production process should be highly productive and the product should be put on the market as soon as possible.
3. Try to reduce manufacturing costs
4. Pay attention to reduce the labor intensity of workers and ensure production safety.
The design reference for mechanical finishing is mainly used to determine other points, lines, and surface positions on the part drawing, which can be effectively referred to as the design reference.
The process reference for mechanical finishing, the reference used in the machining and assembly of parts, is called the process reference. The process benchmarks are divided into assembly standards, measurement standards, and positioning references, depending on the application.
Assembly reference for mechanical finishing. A reference used to determine the position of a part in a part or product during assembly is called the assembly datum.http://www.pump-casting.com/
