On the machining of cylindrical objects with complex curvature

Abstract

This paper describes an integrated approach to the design and manufacture of cylindrical type objects with complex curvature. The modules in this system include the scanning of the object, its surface description and subsequent modification, the tool path generation, and the NC machining of the object. The operation of each module is illustrated in a case study involving the design and manufacture of a shoe last for orthopedic footwear.
