Development of Cutting Temperature Model Based on Experiment and Analysis of its Influencing Factors in Cutting ADI

Abstract Austempered ductile iron (ADI) is a difficult material with severe tool wear during machining, due to the high cutting temperatures in the cutting zone. In this paper, the mathematical model of the cutting temperature is developed based on the turning experiment, and the impact of cutting speed, feeding speed, and cutting depth on the cutting temperature of turning ADI is studied. When the cutting speed and the feed speed increase, a large amount of heat cannot be dissipated, and the cutting zone temperature increases. When the cutting depth increases, the increase of the heat dissipation area makes the cutting temperature change not obvious. This research has important engineering significance for studying the cutting mechanism of ADI and improving cutting efficiency.
