摘要

Temperature plays an important role in the life of cutting tools.However,it is sometimes difficult to observe instantaneously because of limited data acquisition,especially for the textured tool.In this paper,the performance of microgroove textured cutting tools for three-dimensional(3D)oblique dry turning of AISI 1045 steel was studied by finite element simulation.The effects of width,depth and spacing of strip micro-texture on cutting temperature and the effect of cutting speed on cutting temperature of strip microtexture tool were studied.The results show that the maximum temperature of the tool and the tip temperature first increase and then decrease with the increase of micro-texture width.When the micro-texture depth increases,the maximum temperature and the tool tip temperature decrease first and then increase.The highest temperature and tip temperature of the tool gradually increase with the increase of micro-texture spacing.The highest temperature and tip temperature of the tool increase with the increase of cutting speed,feed speed and cutting depth.In addition,the effective mechanism of micro-texture parameter for the temperature was proposed.It provides profound guidance for optimizing the microstructure parameters and cutting process of cutting tools according to cutting temperature in this study.It also provides an effective and practical method for the design,innovation and development of microtextured tools.
