一、前言刀具在切削过程中产生的切削力,切削热和前刀面上的积屑瘤等,严重地影响着切削加工质量。本文用大量的试验对此进行了观测研究,同时也进行了理论分析,提出了相应改善措施。二、主要试验仪器和设备 C620-1车床,液压牛头刨床,三向测力仪,热电偶测温仪,x—y函数记录仪, I. INTRODUCTION The cutting force generated by the cutting tool during cutting, the cutting heat and the built-up edge on the rake face, seriously affect the quality of cutting. In this paper, a large number of experiments were carried out to observe the research, but also conducted a theoretical analysis, put forward the corresponding improvement measures. Second, the main test equipment and equipment C620-1 lathes, hydraulic shaper, three-way dynamometer, thermocouple thermometer, x-y function recorder,
