摘　　要：本文对不同烧结温度下的预烧结3Y-TZP陶瓷开展铣削试验,分析了不同铣削参数对3Y-TZP陶瓷铣削力、铣削温度的影响规律,并对切屑形态和已加工表面质量进行了研究。结果表明:3Y-TZP陶瓷的切削性能随预烧结温度显著变化,在1100℃及以下,已加工表面的凹坑缺陷较严重;在1300℃及以上时,因铣削力和铣削温度过高而不再适合切削加工;预烧结温度为1200℃时可获得最好的切削性能。在任何预烧结温度下,增大主轴转速和每齿进给量都会增大铣削力和铣削温度,且每齿进给量的影响更大。A series of milling experiments are carried out on 3Y-TZP ceramics prepared at different sintering temperatures.The effects of different milling parameters on the cutting forces and temperatures of 3Y-TZP are analyzed,and the chip morphologies and machined surface quality are studied.The results show that the machining properties of 3Y-TZP ceramics vary significantly with the sintering temperature.At 1100℃and below,the cavity defects of machined surfaces become more pronounced.At 1300℃and above,the milling forces and temperatures become too high to conduct further machining.The best machinability can be obtained for 3Y-TZP ceramics sintered at 1200℃.At any pre-sintering temperature,increasing either the spindle speed or the feed per tooth tends to elevate the milling force and milling temperature,and the feed per tooth exhibits more significant impacts.
