摘　　要：切削力是高速切削加工过程中的一个重要的因素。本文采用sialon陶瓷刀具对镍基合金In-conel 718进行了高速车削试验。研究了不同切削速度下切削力、刀具磨损和表面粗糙度相互关系。通过切屑的宏观形态计算得到定量的切削变形系数、剪切角、剪应变,直观分析考察了Sialon陶瓷刀具加工镍基合金时变切削力与形系数及剪切角大小随速度变化的规律。Chip is one of the important factors in high--speed cutting. In this paper,Sialon ceramic tool was used in turning of Ineone1718. The interactions of the cutting force, tool wear and surface roughness were analyzed at different cutting speeds. The deformation coefficient, shear angle, shear strain were calculated by the analysis of the macro chip formation. Rules of variation of the cutting force and deformation coefficient, shear angle, at different cutting speeds were investigated in high-- speed turning of Inconel 718.
