GFRP, because of their superior strength-to-weight and stiffness-to-weight ratio, are used increasingly in high-performance applications. But the users of this material have faced a difficulty to machine them. The major trouble in cutting GFRP is the decreased tool-life, the inferior surface quality and others. The purpose of this study is to clarify the wear characteristic of the tool, to find the suitable cutting condition in trimming GFRP with endmill. The main results obtained are as follows : (1) The shape of cutting tool caused by wear has some variation with type of GFRP. And the tool life is affected considerably by fiber structure in each layer rather than the whole fiber content. (2) Machined surface in cutting GFRP depend on engage angle to fiber direction mainly. (3) Oscillate cutting in which endmill is moved up and down has some effects on improving tool life.
