在金属切削非成型表面的精加工中,付后刀面的作用至今尚未得到国内外研究工作的足够重视。本文对付后刀面的作用及熨平切削形成光洁表面的过程作了初步研究,证明在一定范围内采用新型刀具几何形状进行熨平切削优于一般切削,有进一步研究和推广的价值。一、熨平切削的提出 In the metal cutting non-forming surface finishing, pay the role of flank has not yet been enough attention to the research work at home and abroad. This paper deals with the role of flank and the process of smooth cutting to form a smooth surface. It is proved that using a new tool geometry for ironing is superior to general cutting in a certain range, which has the value of further research and promotion. First, the iron cutting proposed
