对钛基复合材料车削时的车削温度和刀具磨损形态进行试验研究，结果表明，在相同条件下，两类刀具的切削温度随切削速度上升而提高，且在较低速度范围内随切削速度增大车削温度上升趋势明显，较高速度范围内上升趋势较缓；随着刀具磨损量从VB=0mm上升至VB=0.2mm，虽然硬质合金K313刀具的切削温度上升幅度小于PCD刀具，但PCD刀具的切削温度始终远小于硬质合金K313刀具，且PCD刀具的耐用度远好于K313刀具；PCD刀具的磨损形式以磨粒磨损为主，而K313刀具以粘结磨损为主。%This paper deals with cutting tem-perature and tool wear. The experiment results indicate that under the same conditions, both the PCD and carbide tools’ cutting temperature increases with the cutting speed increasing, and increases faster in the lower cutting speed with the improvement of cutting speed, but increases slow-er in the higher cutting speed; With the tool wear rising from 0mm to 0.2mm, though PCD tool’s cutting tempera-ture rises faster than carbide tool, the former is lower than the later, and PCD tool’s life is much more than carbide tool’s life; The main wear form of PCD tool is particle at-trition, while carbide tool is adhesion wear.
