中文摘要:
      主要采用变进给试验法,开展了正弦变进给高效铣削Ti40阻燃钛合金试验和理论研究。建立了正弦变进给变化幅度、变化周期及进给步持续时间与刀具耐用度的关系模型,并对模型参数进行优化,结果表明:当进给变化幅度为11.72%,变化周期为120s,进给步持续时间为5s时,刀具耐用度相比传统铣削,增长幅度最高可达33%。变进给铣削Ti40阻燃钛合金改变了刀具磨损的形态和机理,主要表现是增大前刀面与切屑的接触面积,改变月牙洼磨损的位置,同时减小月牙洼磨损的深度和磨损速率,增强铣削中刀具切削刃强度,从而提高了刀具耐用度。
High Performance Milling of Ti40 Alloy through Variable Feed Method

英文摘要:
      This paper presents a method for improving the cutting tool life by varying the feed throughout the milling process of Ti40 burn resistant titanium alloy. In this research, the model between tool life and the feed variation amplitude, period and step duration of the milling was constructed and the optimal feed variation parameters were selected. Experimental results show that the optimal sinusoidal feed milling parameters were 11.72 percent sinusoidal feed variation amplitude, with 120 seconds one period and 5 seconds incremental steps, which increase the cutting tool life by a maximum of 33 percent. In comparison with constant feed processes, variable feed milling changes the mechanism of the tool rake face by increasing the tool-chip contact area, change the crater position and decrease the crater wear depth, thus strengthens the tool edge and increases tool life.
