汽缸体的汽门室平面是在单轴龙门铣床上用多齿盘铣刀加工的。加工时由于机械震动,必须分两次走刀,而且走刀速度很低。这样生产效率不但不高,刀具寿命也很短。我们曾经多次改进刀具的几何形状进行试验,但机床的震动都没有获得彻底解决。后来经过分析,认为主要问题出 The cylinder block’s valve chamber plane is machined with a multi-spur cutter on a single-axis gantry milling machine. Machining due to mechanical vibration, must be divided into two passes, and walking speed is very low. This production efficiency is not only not high, tool life is also very short. We have repeatedly improved the geometry of the tool to test, but the machine vibration have not been completely resolved. After an analysis, that the main problem out
