Effects of cutting parameters on tool temperatures in intermittent turning with the formation of serrated chip considered

Abstract Taking the formation of serrated chip into account, a theoretical method for prediction of tool temperatures in intermittent turning was proposed to reveal the effects of cutting parameters on tool temperatures. The evolution of heat flux during the formation of saw-tooth chip was analyzed. Based on the established analytical model, the development of transient average tool temperatures with cutting time was investigated. The mean values of transient average tool temperatures were obtained and the effects of cutting parameters on tool temperatures were revealed. It was found that feed rate and depth of cut had greater effects on the maximum value of heat flux in saw-tooth chip formation than they did on the minimum value. Because of the alternation of cutting periods and non-cutting periods, the transient average tool temperature evolved cyclically with the cutting time in the whole cutting process. Tool temperatures developed cyclically with the cutting time in the cutting period due to the periodical formation of saw-tooth chip. Compared to the final stage of cutting period, tool temperature increased much more quickly in the initial stage. Relatively large feed rate and relatively small depth of cut should be adopted to acquire the lowest tool temperature.
