Cad system, program for running the system, and recording medium having the program recorded therein

A CAD system comprising a processing information group and a process definition, the processing information group including:

• a processed-body division which stores a part whose material substance is to be removed by a series of processing operations, as a body for each of the process operations by pre-defined work instructions given via an input device;
• and a process-contents division which stores information about work contents of each process operation in relation to the body, the process definition group containing definitions of a plurality of process operations, upon selection from the process operations via the input device and selection of parts as CAD data to be processed via the input device in an original product body, shape information is extracted from the original product body based on the work instructions for each of the selected parts to be processed and tools and parameters for processing the extracted shape are determined based on the selected processing operations and the extracted shape information, processed bodies as CAD data are generated separately from the parts to be processed, the generated processed bodies are stored in the processed-body division, and the determined tools and parameters are stored in the process-contents division.
