Cutting parameter study of CFRP machining by turning and turn-milling

The use of carbon fibre reinforced plastic (CFRP) structures in rotationally symmetrical components opens up a new field of lightweight construction with great potential for reducing the mass of moving components. Due to the material anisotropy, the machining of these structures can cause component damages. In this paper, the machining results of CFRP shafts conducted by turning and orthogonal turn-milling are presented. The characteristics of the applied processes are evaluated concerning the achievable shape and surface quality of the workpiece. Furthermore, the possibilities for the machining of fits on CFRP shafts are discussed.
