摘要
为克服传统的焊接固定式钻头的不易更换、工艺性差的缺点,设计开发了机械夹持式的硬质合金钻削群钻。利用遗传算法给出了基于最大生产率的钻削参数优化结果,并进行新型机夹式刀具的钻削高锰钢的试验研究,得出了机夹式刀具的设计是可行的结论。同时,采用新型刀具加工,切削力和扭矩都相应的有所下降,其中轴向力下降了20%左右,扭矩下降了15%左右,切削效率也就得到了提高。
In order to overcome the shortcoming that the traditional welding stationary type drill bit is not easy to be replaced and has poor manufacturability, the meehanieally-clamped cemented carbide multifaee drill was developed. The optimization result of eutting parameter based on the greatest productivity is given by genetic algorithm, and the experimental study of drilling high manganese creel was carried on. The conclusion that the design of mechanically--clamped cutting tool is feasible is obtained. Cutting force and torque are decreased by using new cutting tool, wherein the axial force and efficiency are decreased 20% and 15%, respectively, so the cutting effieieney is improved.
