T/R组件封装用铝硅合金高速铣削试验研究

摘要

In order to solve the problems of low efficiency and high cost in the general milling process of aluminum silicon alloy for T/R modules, in this paper, a high speed milling test was performed on aluminum silicon alloy for T/R modules with a triple-edge hard alloy coated tool.The influence of cutting amount, spindle speed, back engagement of the cutting edge etc to cutting force and cutting temperature are explored, and the changing trend and reasons of cutting force and cutting temperature under common cutting parameters are analyzed.The reasonable high speed milling parameters of aluminum silicon alloy CE11 were obtained through experiments, which has certain guiding significance for improving the cutting efficiency and processing quality.%为解决T/R组件封装用铝硅合金材料普通铣削加工过程中效率较低、加工成本较高的问题, 文中采用三刃硬质合金端面铣刀对某T/R组件封装用铝硅合金CE11进行了高速铣削试验, 探索了其在高速铣削过程中, 切削量、主轴转速、背吃刀量等对切削力、切削温度的影响, 分析了常用切削参数下切削力及切削温度的变化趋势及原因.通过试验得到了CE11较为合理的高速铣削参数, 对提高切削效率及加工质量有一定的指导意义.
