Description
Summary:This study deals with the identification of the topography of the surface that is created by machining composite materials with natural fibres (biomaterials, wood-plastic composites – a material with plastic matrix and natural reinforcement). The final surface was evaluated based on tool geometry (turning technology), and the influence of the tool on selected evaluating parameters of the obtained surface was evaluated using a non-contact method, applying an optical profilometer (MicroProf FRT). After machining the surface, characteristic relief (a trace on the surface of the material) was visible depending on the machining factors combination (machine, tool, workpiece, and fixture). The initial material also played a prominent role in the surface monitoring, in relationship to the composition of the material and the interaction between the matrix and reinforcement, i.e., detection of defects in the area of the interaction between the initial components.
