Temperature analysis in the manufacturing phase of the product is necessary for improving the operational performance of the workpiece. In screw whirling milling, the analysis of cutting temperature is different from turning or milling due to the complicated contact characteristics between the tool, workpiece and chip. In this study, a temperature model is developed for predicting the temperature distribution of the cutting area in screw whirling milling at the two cutting stages. Temperature experiments on the ball screw shaft are carried out in whirling milling machine under different cutting conditions to verify the proposed model. The maximum temperature of the cutting area increases with the cutting speed at first and decreases subsequently. The maximum temperature increases with the rotation of the tool ring and then decreases in one cut.
