Experimental Evaluation on Shape and Control of Chip in Milling of PE WPC

Abstract

This paper the regular patterns of chip flow, chip curler radius and thickness under different cutting parameters when processing PE WPC with different wood flour contents under the condition of up milling and down milling. Compared with up milling, down milling has greater impact on chip flow direction and cutting speed. However, there are more dust-shaped chips in the up milling. In the down milling, chip curler has less change with cutting parameters. Only when the feed speed is 14m/min or the cutting speed is 1800m/min, the chip curl radius is larger. The chip thickness increases when the feed speed or the cutting width increases and decreases when the cutting speed increases.
