Two idealized fiber reinforced plastic (FRP) composites were machined on a planer to examine ductile and brittle reinforcements, fiber orientation, cutting tool geometry, depth of cut, and cutting speed affects on the machining process. Machining forces were measured and the machining stresses analyzed. Semi-empirical models were then proposed to describe the cutting process. The models were based on the premise that cutting energy for the composite is the sum of the cutting energies for the constituents and the energy to debond the fiber-matrix interface. It was observed that the fiber and fiber-matrix interaction played a major role in the quality of the machined fiber reinforced plastics component as well as in dictating the tool life.
