Abstract
Abstract A CAD/CAM unit data generating process which allows machining control data to be generated efficiently, and independently of the sequence of shape definition. Machining sequence information is derived from shape defining information and machining information generated in correspondence with machining conditions. The machining sequence information is rearranged in accordance with selected conditions for rearranging the machining sequence information, such as machining type, height priority, tool sequence, and other operator inputs. The results are stored for future access.
