平面铣削刀具前刀面瞬态切削温度的研究
Modeling and analysis of transient cutting temperatures on tool rake face in peripheral milling
摘要
Abstract
Tool temperatures have major impacts on tool life,tool wear,etc. Hence,a reliable tool temperature predicting has an important significance for properly selecting cutting parameters, optimizing the NC programs. Thermal conditions in interrupted cutting processes such as peripheral milling differ from those in continuous cutting processes such as turning. A novel one-dimensional heat transfer model of the tool temperatures on tool rake face during peripheral milling is presented using mathematical physics methods. Temperature distribution on the tool rake face during peripheral nulling is predicted using the proposed analytic methods. The enhanced air convection cooling effect of idle cutting time on tool temperatures is taken into account. The results show that tool temperatures depend primarily on cutting time and idle cutting time. The model is verified with intermittent turning experimental tests reported in the literature. Temperatures of peripheral milling is however slightly lower than those in intermittent turning.关键词
