CAD SYSETM, PROGRAM FOR RUNNING THE SYSTEM, AND RECORDING MEDIUM HAVING THE PROGRAM RECORDED THEREIN

摘要

A CAD system capable of generating the shape body of a machined portion and the contents of machining by automatically recognizing the machined portion by utilizing CAD data on product shape only, comprising a machining information group (15) having a machined shape body part (15a) storing the portion where material is removed by machining as the shape body for each machining and a machining contents part (15b) storing tools and parameters as information on the contents of machining in connection with the shape body and a machining definition group (18) defining a plurality of machining types beforehand.
