Effects of Spindle Speed on Surface Qualities in WPC Sawing
Wood plastic composites (WPCs) are the industrial products. It is made out of wood waste fibre and waste plastic glued together by heat and pressure. Nowadays WPCs products are preferred over solid wood in many applications due to certain comparative advantages. Sawing is the machining operation frequently used in manufacturing parts of WPCs. The aim of this article is to study the effect of cutting speed on surface roughness in different WPCs sawing. A plan of WPCs sawing experiments was preformed with prefixed cutting parameters. The objective was to establish correlation between rice hull flour/PE composite, rice hull flour/PP, rice hull flour/PVC and cutting speed with the surface roughness after sawing. The results show that the spindle speed had significant effects on the surface qualities of rice hull flour/PE composites, rice hull flour/PVC composites and rice hull flour/PP composites. The advantage of using a high cutting speed in WPCs sawing is evident. With appropriate cutting parameters, one can obtain surfaces with Ra＜6μm and to get surfaces qualities (dimensional precision) in workpiece of different WPCs.
