摘　　要：本文针对金刚石绳锯的柔性加工以及长锯切弧区的加工特点,采用弧区内分段的实验方法,在弧区七个位置选取了50 mm的微段,对每个微段进行锯切力的测量,进而总结出锯切加工弧区内锯切力的分布情况。研究结果表明:当线速度和进给速度较小时,整个弧区的锯切力的波动较小,随着线速度和进给速度的增大,弧区锯切力在整个弧区的波动随之变大;绳锯在进入弧区端的锯切力要大于离开弧区端的弧区锯切力。Regarding the flexible process and long cutting arc of diamond wire saw when cutting granite,in this paper,cutting force distribution was studied by arc-dividing method.The sawing force of each micro section of 50 mm long at 7 different distances was measured.The results indicated that,the sawing force at lower cutting speed and lower feed speed did not fluctuate a lot.Along with the increase of the linear speed and the feed speed,there was quite large sawing force fluctuation in the whole cutting arc zone.The sawing force at the entering end was higher than that at the exit of the cutting arc zone.
