精密机械零部件加工在进行设计的过程中不仅要满足其使用要求，即具备其所要求的工作的能力，在进行操作的过程中同时还应当满足生产要求，精密机械零部件加工在进行设计的过程中便于加工而加工费用很低，这样的零件在一定程度上就会被称为具有良好的工艺性。

精密机械零部件加工工艺性的基本要求

1. 毛坯在进行选择的过程中，需要采用其合理额机械制造中的毛坯制备方法，在进行操作时会直接利用其型材、铸造、锻造、焊接以及冲压等方法，在进行使用时其毛坯的选择和具体的生产技术条件是有关的，一般情况下取决于生产批量以及才能性能和加工可能性等。

2. 精密机械零部件加工的结构在进行设计的过程中是非常的简单的，在进行操作时主要是采用最简单的表面以及组合，在一定程度上同时还应当尽量使用加工的表面的数目最少和加工面积比较小。

3. 精密机械零部件加工规定适当的制造精度和表面粗糙度的零件的急啊佛那个费用会随着其精度的提高而增加，在进行操作时在精度较高的情况下，这样的增加极为显著，因此，在没有充分根据时，不应当追求高的精度。同理，零件的表面粗糙度也应当根据配合表面的实际需要，作出适当的规定。

4. 精密机械零部件加工在一定程度时其设计出工艺性良好的零件，在进行设计的过程中就必须要和工艺技术员工相结合并善于向他们学习，此外，在金属工艺学课程和手册中也都提供了一些有关工艺性的基本知识，可供参考。

精密机械零部件加工的表面粗糙度在一定程度上可以有效的反应其零件表面的微观几何形状的误差的一个非常重要的技术指标，在进行使用时这是检验零件表面质量的主要依据。

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
