TiCN基硬质合金刀具切削性能与切削机理研究

通过系统地切削试验，研究了TiCN基新型硬质合金刀具在耐磨性、抗冲击性、切削力、刀一屑摩擦系数、加工表面质量等方面的切削性能特点；并通过一定的理论分析，探讨了TiCN基硬质合金综合性能优越的切削机理。研究所得大量切削试验数据及回归经验公式等，可供TiCN基硬质合金刀具推广应用时参考。

AN EXPERIMENTAL STUDY OF THE CUTTING PERFORMANCE OF TICN CERMET TOOL

With systematic cutting experiments,the cutting performance of the newly developed TiCN-cermet tool was studied in terms of its wear resistance, interrupted cutting behavior,cutting force, tool-chip friction and the machford surface roughness,etc,The cutting mechanisms in accordance with the performance of the tool was clarified with some experimental and theoretical analyses. The cutting data and empirical formulae withdrawn from the study could do a help to the proper application of the TiCN cermet tool.
