主要是研究在高速粗铣削加工淬硬钢AISIH13时,为了获得高的金属切削量,采用高轴向切削深度(10mm≤轴向切削深度≤20mm)的可能性。研究结果表明,在高轴向切削深度情况下,选择往复行切刀具路径方案最为有利,从而使刀具寿命长、金属切削量大、切削加工时间短、金属体积去除率高。 The main concern is the possibility of using high axial depth of cut (10 mm ≤ axial depth of cut ≤ 20 mm) for high-speed roughing of hardened steel AISIH13 in order to achieve high metal cutting. The results show that under the condition of high axial depth of cut, the reciprocating cutter path selection is most advantageous, which results in long tool life, large metal cutting, short cutting time and high metal removal rate.
