Abstract: Wood-plastic composites present the specific group of composite materials consisting of plastic matrix and natural reinforcement in meal or fibre form. There are publications which are presented in the scientific databases whose field of investigating is the mechanical and physical properties, the way of manufacturing and chemical composition of WPC materials. However, there is only a small percentage in the field of machining of composite materials with the natural reinforcement. The presented article is focused on the surface topography evaluation of wood plastic composite materials after turning. Parameters of surface roughness were evaluated using the optical contactless method - MicroProf FRT optical profilometer. During the turning process, a trace is formed on the surface profile - in the form of thread with the expected pitch. Surface roughness parameters and conclusions were formulated according to obtained results.
