钛合金高速铣削表面完整性研究

Study of surface integrality on high speed milling titanium

研究了钛合金TC4的高速铣削。着重讨论了高速铣削钛合金TC4已加工表面完整性的问题,重点研究了表面粗糙度、表面变质层等因素对表面完整性的影响。研究结果表明,切削速度在v=200～350m/min范围,钛合金TC4高速铣削获得的加工表面完整性较好。

Research on high speed milling TC4 is mainly done in this paper. A problem about machined surface integrality of TC4 is discussed. The effect of surface roughness and transmutative layer on machined surface integrality is studied. The experimental result shows that an improved surface integrality of TC4 can be obtained when milling speed is 200 - 350m/mm.
