摘　　要：为探究氮化硅陶瓷超声辅助铣磨加工中铣磨温度的变化,以提高陶瓷加工质量,降低其热损伤,用FLIR SC325红外热像仪为测量工具,以单因素实验法研究主轴转速、进给速度、切削深度和超声振动作用对铣磨温度的影响。结果显示:主轴转速升高,铣磨最高温度逐渐降低;在相同的切削长度下,进给速度加快,加工时间缩短,最高温度稍有降低;切削深度对铣磨最高温度的影响呈现阶段性;在无冷却液干磨的条件下,超声铣磨的最高温度稍高于普通铣磨的最高温度。In order to explore the change of milling temperature in the ultrasonic assisted milling of silicon nitride ceramics,improve the quality of ceramic processing and reduce its thermal damage,the effect of spindle speed,feed speed,cutting depth and hyper vibration on the milling temperature was studied by single factor experiment method with FLIR SC325 infrared thermal imager as measuring tool.The results show that the highest temperature of the milling decreases gradually with the increase of the spindle speed,and that the faster the feed speed,the shorter the processing time and lower peak temperature in the same cutting length.The effect of cutting depth on the highest temperature of milling is periodic.The highest temperature of ultrasonic milling is slightly higher than that of common milling under the condition of dry grinding without coolant.
