Abstract
The paper deals with a comparison of the surface roughness of WPC (Wood Plastic Composite) after the machining (turning). Turning was performed with constant speed rotation and constant depth of cut. The goal of this paper was the observed change of average maximum height Rz (roughness average Ra) with change of feeds (interval of feed f=0.1 to 0.61mm) and design recommendations resulting from acquired knowledge. Keywords: Wood Plastic Composite, machining, surface roughness
