摘要: 本文根据用高速钢刀具对耐磨铸铁进行精切削试验的结果,论述了脆性金属耐磨铸铁薄切削时刀具前角、后角合理值的确定,切削厚度a、切削速度v以及刀具刃口圆半径ρ对切削温度和加工光洁度等的影响,指出在薄切削下加工铸铁时,a/ρ比值的选择值得重视。

Abstract: This paper presents the experimental investigation of extra-fine metal-cutting for highphosphorus cast iron showing the determination of the reasonable rake angle & fhe reasonable relief angle of the cutting tool, the influences of the thickness of cut, the cutting speed & the radius of the tool-tip on the cutting temperature & the surface finish of the workpiece It is pointed out that the selection of a reasonable a/P ratio is important during exfra fine metal-cutting for cast iron.
