This study deals with new practical fabrication of end mills based on 3D-CAD/CAM. End mills with arbitrary shapes generally difficult to produce are useful in upgrading machining accuracy and efficiency. Our tool fabrication CAD/CAM potentially produces end mills with arbitrarily shaped cutting edge. In order to make them practical, we developed a way to design the cutting edge shape and NC data generation for a 5-axis controlled tool grinding machine. The resulting system enables produces practical, arbitrarily shaped end mills with shape precision comparable to their commercially available counterparts.
