CARDAM-an integrated design and manufacturing system for roll forming tools

The article deals with the development of an integrated design and manufacturing system (CARDAM) for roll forming tooling. The roll forming process has been organised into three distinct modules: roll form design, roll profile editing and NC processing of roll profiles. The roll design module automatically generates section drawing, flower pattern, mill parameters, and roll drawings to design specifications. The roll editing module generates the roll profile geometry data essential for the NC processor. This provides the link for integrating CAD and CAM facilities. The NC processor uses roll profile data as input geometry and finally generates NC codes for the roll machining process. The article brings out the facilities incorporated into the CARDAM system through a design example
