Creation of Curved Surface by Lathe Turning -Development of CAM system using original tool layout-

Abstract The machining of 3D curved surfaces with an un-axisymmetric axis by lathe turning is proposed considering the best machinable tool layout. The best offset tool layout from the central axis of a spindle enables us to machine curved surfaces and to obtain a long tool life for hard material workpieces using a rotary tool. A dedicated NC program for the 3D surface using the original CAM system has been developed and applied to what. The machining results and the validity of our system are evaluated in this paper.
