It is strongly requested to develop a new CAM system to shorten the drill fabrication time, to reduce material costs, and to create a new drill configuration by predicting its characteristics. Current drill shape prediction system cannot necessarily treat drill cross-section shape including the cutting edge, groove and so on, mathematically. The system becomes practical if these drill specification is mathematically formulated. The study reports the development of a system to predict not only cross-section shape but also various parameters from grinding wheel data of drill making.
