摘要
对大进给铣削TC21钛合金时的刀具磨损形态进行了宏观和微观分析:由宏观来看,大进给铣刀的前、后刀面磨损不均匀,其磨损严重区域在最大切深附近;由微观来看,大进给铣刀的前、后刀面都有大量的钛合金粘附物、间距不等的热裂纹和刀具材料的剥落出现。
Tool wears are studied with macroanalysis and micro-analysis method in high feed milling of titanium alloy TC21.From the macro-analysis,it can be seen that tool wears in rake face and flank face are not uniform and the serious worn area is near the maximum cutting depth.From the micro-analysis,much attached titanium alloy,cracks with different distance between adjacent ones and breakage are found in both faces.
