Abstract

This paper presents the impact of the change of cutting parameters on cutting force and cutting vibration by the milling experiment of PE WPC. In the text, 60% wood flour content and 70% wood flour content WPC are compared in up milling and down milling. The result shows that cutting force shows a progressive increasing trend as the feed speed increasing. The cutting force in up milling is totally smaller than in down milling with the change of cutting speed. Cutting force shows an increasing trend with the cutting width increasing. The impact of feed speed on cutting vibration is more obvious. The cutting vibration of 60% wood flour content is more susceptible than 70% wood flour content. In the cutting speed experiment, the cutting vibration in up milling is obviously bigger than in down milling. The cutting vibration of 60% and 70% wood flour content is almost the same in down milling. However, it is opposite in up milling. The cutting vibration shows a progressive increasing trend in down milling and steady in up milling as the cutting width increases.
