G.F.R.P. is widely used in the industry as materials of parts of various precesion instruments because of excellent mechanical properties, water proof, endurance of drugs, corrosion resisting, heat insulation and separation. Therefore it is recently demanded the necessary of cutting work as well as forming in the extreme, but the tool wear greatly occurs in cutting of G.F.R.P. and it is depended upon the cutting conditions; cutting speed, cutting distance and too angle. This study has analysised and examined the tool wear measured by the model formular of tool wear and experiments. The main results obtained are as follows. 1. Approximate wear value of the model formular of tool wear almost approaches to value measured by experiments. 2. The edge wear is varied with the direction of Glass Fiber. 3. The wear of cutting edge is nearly increased proportion to the cutting distance.
