精密(mi)機(ji)械零部件加(jia)工在進行設計的過程中不僅要滿足其使用要求，即具備其所要求的工作的能力，在進行操作的過程中同時還應當滿足生產要求，精密機械零部件加工在進行設計的過程中便于加工而加工費用很低，這樣的零件在一定程度上就會被稱為具有良好的工藝性。

In the process of design, precision mechanical parts processing should not only satisfy its use requirements, that is to say, have the ability to work as required, but also meet the production requirements in the process of operation. Precision mechanical parts processing is easy to process and the processing cost is very low in the process of design. Such parts will be called good work to a certain extent. Artistic quality.
Basic Requirements for Processing Technology of Precision Machinery Parts
1. In the process of choosing the blank, it is necessary to adopt the method of preparing the blank in the reasonable amount of mechanical manufacturing. In the process of operation, the methods of profile, casting, forging, welding and stamping are directly used. The selection of the blank and the specific production technical conditions are related, generally depending on the production batch and the capability, performance and processing possibilities. And so on.
2. The structure of precision machine parts processing is very simple in the process of design. The simplest surface and combination are mainly used in operation. To a certain extent, the least number of machined surfaces and the smallest processing area should also be used as far as possible.
3. Precision mechanical parts processing stipulates that the urgency of parts with appropriate manufacturing accuracy and surface roughness will increase with the improvement of their accuracy. In the case of higher accuracy in operation, such an increase is extremely significant. Therefore, high accuracy should not be pursued without sufficient basis. Similarly, the surface roughness of the parts should be regulated according to the actual needs of the matching surface.
4. Precision mechanical parts processing to a certain extent when they design good parts, in the process of design must be combined with process technicians and good at learning from them, in addition, in the course of metal technology and manuals also provide some basic knowledge about process, for reference.
To a certain extent, the surface roughness of precision mechanical parts can effectively reflect the errors of their surface micro-geometry. It is a very important technical index to test the surface quality of parts when it is used
