Abstract
The study deals with five-axis control tool path generation for the sculptured surface machining with conicoid end mills. Ball end mills are in general utilized for the sculptured surface machining. However, it takes much time to finish such complicated surfaces with high accuracy due to the nessesity of a small amount of pick feed. Thus, a new cutting method is proposed to use special cutting tools, called conicoid end mill, for the sculputured surface machining. The study deals with the development of new CAM system with ellipsoid and hyperboloid end mills as well as paraboloid. From the experimental results, it is found that the conicoid end mills have the potential of reducing a machining time remarkably.
