Depth of reluctant uncut and deformed part have been measured by original methods in unidirectional prepreg cutting. Depth of reluctant uncut that significantly controls accuracy of dimension were attributed to elastic recovery of the machined surface layer. Depth of reluctant uncut could be determined by measuring a step between pre-cut surface and newly generated surface using an electric micrometer. Deformed part that corresponds damaged layer of metal machined surface could be observed by an optical microscope with Nomarski differential interference contrasts. Measurement results indicated that both values were markedly affected by rake angles, fiber angles, and depth of cut. Tangential and normal cutting forces were remarkably dependent on depth of deformed part and reluctant uncut respectively.
