Sum m m a r y .涂层零件制造工艺规划中最重要的问题之一是选择涂层沉积毛坯精度成形要求与最终涂层零件之间的最佳关系。涂层的加工过程不同于整体材料的加工过程。某些涂层，特别是耐磨涂层的低可加工性的原因之一是含有硬颗粒的强研磨性涂层的结果。因此，在制造操作中建立合理的尺寸公差是重要的，并且对工艺过程的质量和制造零件的成本具有重大影响。本文提供了一个完整的方法，几何尺寸和公差的制造涂层零件。关键词：公差，涂层，几何尺寸，公差分析。
S u m m a r y . One of the most important problem in process planning for manufacturing of coated parts is the selection of the optimal relationship between the requirements for precision shaping of blanks for coating deposition and finally coated part. The processes of coatings machining differs from the machining processes of monolithic materials. One of the reasons of low workability of some coatings, especially wearresistant, is a consequence of strong abrasivity coatings which contain hard particles. Therefore, establishment of rational dimensional tolerances in manufacturing operations is important and has a significant impact on the quality of the technological processes and the cost of manufacturing parts. This paper provides an integrated methodology for geometric dimensioning and tolerancing in manufacturing of coated parts.
