In recent years, the efficient machining of workpieces with a complicated shape has being increased in terms of realizing the products with compact design and sufficient functionality. 5-axis control machining center is suitable to meet such a requirement. However, it is necessary to obtain adequate tool postures to avoid interference between the cutting tool and the workpiece while machining workpieses with complicated sculptured surface. This study deals with rapid tool path generation for 5-axis control machining to treat such complicated product shapes on the basis of a proposed method. For tool path generation, the product shape is divided into small area. Each divided area is subjected to interference check. This new CAM system can generate automatically interference-free NC data in 5-axis control machining. The validity of the developed system is demonstrated with machining simulation and experiment.
