摘要/Abstract

摘要： 面向切削状态监测和加工工艺智能优化对切削温度在线精确感知的需求，利用负温度系数热敏陶瓷的阻温特性和结构陶瓷的高耐磨性，设计了一种基于异种陶瓷复合的新型温度感知刀具，并通过微波烧结技术制造了该智能刀具，最后基于刀具上3个测温点的温度值对刀具切削区温度场进行了重构。该温度感知智能刀具最高感知温度>700℃，响应迅速。在v_c=150 m/min、a_p=1.0 mm、f=0.075 mm/r干式车削镍基高温合金GH4169时，刀具在25 s达到热平衡，刀具上3个测温点的温度值分别为425℃、204℃和188℃，刀具最高温度出现在前刀面靠近主切削刃位置，最高温度达1 579℃，整个刀尖区域的温度不低于1 000℃。

Abstract: Orienting to the requirements of on-line accurate perception of cutting temperature for cutting state monitoring and intelligent optimization of machining process, a new type of temperature sensing smart tool is designed and prepared by microwave sintering, taking advantage of resistance-temperature characteristics of negative temperature coefficient thermal sensitive ceramics and well wear resistance of structural ceramics. Finally, the temperature field in the cutting zone is reconstructed. The temperature sensing smart tool has quick response and highest sensing temperature is over 700℃. The tool reaches thermal equilibrium at the time of 25 s, and the temperatures of the three temperature sensing points on the tool are 425℃, 204℃ and 188℃, when dry turning the nickel-base superalloy GH4169 under the conditions of v_c=150 m/min, a_p =1.0 mm, f =0.075 mm/r. The highest temperature of the tool occurs at the rake face near the main cutting edge, with the highest temperature of 1 579℃ and the temperature of the entire tool tip region is not less than 1 000℃.

Key words: smart tool, cutting temperature measurement, microwave sintering, temperature filed reconstruction
