Influence of spatial tool inclination on delamination when milling CFRP

The results show that fibre protrusions can be avoided if the cutting velocity is at least partially directed into the laminate plane and if the cutting edge is located partially above the fibre to be cut. The geometrical and kinematic model is applicable to any machining operation, to materials with unidirectional fibre reinforcement and to non-crimped fabrics with unidirectional top layers.
