一、问题的提出采用插齿、剃齿工艺,加工低碳合金钢20CrM.Ti,齿坯锻造后经正火处理至硬度HB156～207的齿轮时,插齿若采用普通几何角度(即前角γ=5°、顶刃后角α_B=6°)的插齿刀,插齿刀齿侧表面经常出现“粘刀”的现象,即插齿过程中插齿刀的齿侧表面粘结铁屑。我们先后采取过一些措施:如更换冷却剂,改变切削用量,插齿刀氮化处理等,但都没有取得明显的效果。由于插齿刀齿侧表面粘屑,使插齿时 First, the question put forward the use of gear shaving, shaving process, processing low-carbon alloy steel 20CrM.Ti, gear blank forging after normalizing to the hardness of HB156 ~ 207 gear, the plunge if the use of ordinary geometric angle γ = 5 °, apex angle α_B = 6 °), the phenomenon of “sticking knife” often appears on the tooth flank surface of the gear shaper, that is, the flank surface of the gear shaper adheres to the iron filings . We have taken some measures: such as replacing the coolant, changing the amount of cutting, gear cutter nitriding, etc., but did not achieve significant results. Due to the gear tooth flank surface of the dandruff, so that when the gear is inserted
