CAD pioneer dies

摘要

Joseph Frisch, a pioneer in CAD and a University of California-Berkeley professor emeritus of mechanical engineering, died June 15 of congestive heart failure. He was 87. Frisch investigated direct numerical control in design and manufacturing as a means to network CNC machine tools. His investigation included developing a method for choreographing a machine and workpiece's movements to create complicated workpiece geometries and shapes. His efforts contributed to changing manufacturing from a craft to a production industry.
