精密機(jī)械零部件加工在進(jìn)行設(shè)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(jìn)行操作的過程中同時還應(yīng)當(dāng)滿足生產(chǎn)要求，精密機(jī)械零部件加工在進(jìn)行設(shè)計的過程中便于加工而加工費(fèi)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。
精密機(jī)械零部件加工工藝性的基本要求
1. 毛坯在進(jìn)行選擇的過程中，需要采用其合理額機(jī)械制造中的毛坯制備方法，在進(jìn)行操作時會直接利用其型材、鑄造、鍛造、焊接以及沖壓等方法，在進(jìn)行使用時其毛坯的選擇和具體的生產(chǎn)技術(shù)條件是有關(guān)的，一般情況下取決于生產(chǎn)批量以及才能性能和加工可能性等。
2. 精密機(jī)械零部件加工的結(jié)構(gòu)在進(jìn)行設(shè)計的過程中是非常的簡單的，在進(jìn)行操作時主要是采用最簡單的表面以及組合，在一定程度上同時還應(yīng)當(dāng)盡量使用加工的表面的數(shù)目最少和加工面積比較小。

4. 精密機(jī)械零部件加工在一定程度時其設(shè)計出工藝性良好的零件，在進(jìn)行設(shè)計的過程中就必須要和工藝技術(shù)員工相結(jié)合并善于向他們學(xué)習(xí)，此外，在金屬工藝學(xué)課程和手冊中也都提供了一些有關(guān)工藝性的基本知識，可供參考。
精密機(jī)械零部件加工的表面粗糙度在一定程度上可以有效的反應(yīng)其零件表面的微觀幾何形狀的誤差的一個非常重要的技術(shù)指標(biāo)，在進(jìn)行使用時這是檢驗(yàn)零件表面質(zhì)量的主要依據(jù)。

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
