This study deals with evaluation method of interference between cutting tool and workpiece in 5-axis control machining. In conventional studies, the 2-dimentional C-Space was proposed in order to generate cutter location considering the interferencebavoidance. In order to accelerate generation of the cutter location, a new calculation method of the 2-dimentional C-Space isbrequired. So, we propose a new idea of discrete 2-dimentional C-Space and high-speed calculation method. The proposedbcalculation method is based on new functions of graphic acceleration hardware (GPU). In the proposed method, geometricbcalculation of the discrete 2-dimentional C-Space is regarded as the drawing process of 3-dimentional computer graphics. As abresult, the high-speed evaluation of tool interference is realized by GPU functions.
