✦ Synopsis
Orthogonal cutting mechanisms in the edge trimming of Graphite/Epoxy laminate with polycrystaUine diamond tools were studied. Chip formation, cutting force, and surface morphology were evaluated with respect to tool geometry, process conditions, and ply distribution in the laminate. As with the trimming of unidirectional panels, discontinuous chips were observed with primary dependence on fibre orientation. Cutting mechanisms for 0 ° and 45 ° plies were identical to those in the trimming of unidirectional material. However, chip formation mechanisms in trimming 90 ° and -45 ° plies of the multi-directional laminate changed due to the support provided by adjacent plies. Empirical cutting force models for principal and thrust force components were constructed by factorial design and regression methods.
