Analytical force model for orthogonal machining of unidirectional carbon fibre reinforced polymers (CFRP) as a function of the fibre orientation

In order to consider tool wear effects, a characteristic description of the cutting edge is proposed using five micro-geometry parameters. The focus of this paper is on the force model, however simulation of tool wear is part of future research. The comparison of the simulated and experimental process forces, depending on the actual wear state and current tool micro-geometry shows a good correlation.
