分析材料的去除原理,探讨离散化切削对齿面质量的影响。传统的加工工艺是铣削、刮削、研磨和磨齿,这些工艺的实质都是接触式的离散切削,而齿面质量的高低(主要是精度和粗糙度)取决于离散化切削程度:当离散程度越高,齿面上的刀痕轨迹分布越明显,齿面质量越低;当离散化切削程度接近连续化时,刀痕的致密度越高,齿面的质量越高。并简要介绍非接触式电化学光整加工和近净成形技术。最后根据以上工艺特点提出展望。
Analyze the material removal principle and discuss the influence of discretization cutting on the tooth surface quality. The traditional machining process is milling, scraping, grinding and grinding, the essence of these processes are contact discrete cutting, and tooth quality (mainly precision and roughness) depends on the degree of discrete cutting: when the degree of dispersion The higher the distribution of the tool marks on the tooth surface, the lower the quality of the tooth surface. When the degree of discretization is close to continuous, the higher the density of the cutting marks is, the higher the quality of the tooth surface is. And briefly introduces the non-contact electrochemical finishing and near-net shape technology. Finally, based on the above process characteristics put forward.
