摘　　要：为了解决航空发动机钛合金叶片磨削加工中砂带使用寿命不足的问题,采用新型氧化铝空心球开展钛合金试样砂带磨削的相关工艺试验研究。通过单因素试验分析氧化铝空心球砂带加工钛合金板材中工艺参数对表面粗糙度和磨削比的影响,确定空心球砂带磨削钛合金参数的合理范围,进而通过正交试验研究磨削压力、磨削线速度、进给速度以及磨粒粒度等因素对表面粗糙度和磨削比的影响程度,确定空心球砂带磨削钛合金的最优工艺参数组合。To solve the problems of shortlife of abrasive belt in aero-engine titanium alloy blade grinding,experimental research on abrasive belt grinding processes of titanium alloy samples was carried out on a new type of alumina hollow-sphere abrasive belt.The effects of processing parameters on the surface roughness and grinding ratio of titanium alloy sample processed by alumina hollow-sphere abrasive belt were analyzed through single-factor experiments,and the reasonable grinding parameter ranges of titanium alloy with hollow-sphere abrasive belt were determined.Then the influence degrees of grinding force,grinding speed,feed speedand grain size on surface roughness and grinding ratio were studied through orthogonal experiments to determine the optimal combination of processing parameters for titanium alloy grinding with hollow-sphere abrasive belt.
