Study on helical milling performance of wood-plastic composites

ABSTR A C T In order to provide scientific guidance for Wood-plastic composite(WPC) helical milling, this paper studied the effects of cutting parameters and tool parameters on cutting force and surface quality in WPC ma-chining with diamond tools. Multiple linear regression model and response surface method are used to evaluate three factors, namely-spindle speed, cutting depth and tool helical angle when the feed speed is fixed at 5 m/min. The applicability of the model is predicted and verified respectively in a given range, and the change law of cutting force and surface quality in helical milling is predicted accurately. The results show that the cutting force increases with the increase of the three factors. The surface quality only in-creases with the increase of the spindle speed. The optimum conditions for low cutting force and excellent surface quality are: spindle speed is 6254 r/min, the feed speed is 5 m/min, the cutting depth is 0.5 mm, and the tool helical angle is 54 degrees. These parameters are recommended to be used in actual WPC machining to improve cutting efficiency.(c) 2022 CIRP.
