| 摘 要： | 采用对角正交回归试验法,研究了用PCBN刀具高速车削钛合金TC4时切削用量对刀具寿命的影响,并分析工件已加工表面粗糙度。通过扫描电镜观察分析,证实刀具的磨损机理主要是前后刀面的粘结磨损及氧化磨损、后刀面磨损以及切削深度线处的沟槽磨损。

| Abstract: | Based on the orthogonal regression test method,the relationship between tool life and cutting parameters in high-speed turning of titanium alloy TC4 with PCBN tool is investigated,and the machined surface roughness is analyzed.Through the observation and analysis by SEM,it is approved that adhesion and oxydation wear on the rake and flank face,flank face wear and notch wear at the depth of cut are the main PCBN tool wear mechanisms. |
