<p>The present invention provides a CAD system, a program for operating the system and a recording medium. The system is capable of automatically recognizing parts to be processed, from CAD data which only contains a product shape, and generating the shape of body to be processed and the work contents therefore. The CAD system includes a processing information group ( 15 ) and a process definition group ( 18 ). The processing information group includes: a processed-body division ( 15 a) which stores a part whose material substance is to be removed by a single or a series of processing operations, as a body for each of the process operations by pre-defined work instructions; and a process-contents division ( 15 b) which stores information about work contents of each process operation in relation to the body. The process definition group contains definitions of a plurality of process operations. Upon selection from the process operations and parts to be processed ( 51' through 59' ) in an original product body ( 50' ), shape information is extracted for each of the selected parts to be processed ( 51' - 59' ) and tools and parameters for processing the extracted shape are determined, a processed bodes ( 51 - 59 ) are generated, the generated processed bodies ( 51 - 59 ) are stored in the processed-body division ( 15 a), and the determined tools and parameters are stored in the process-contents division ( 15 b).</p> |
