Abstract: In order to support sculptured surface design oriented to manufacturing, an embedded-computer-based platform was presented. Two function modules, constraint information modeling module and manufacturability analysis module, were developed and embedded in a CAD/CAM software system. By abstracting manufacturability criterion of sculptured surfaces, an application information model was constructed to extract manufacturing constraints from the geometry shape of sculptured surface. Applied in sculptured surface machining, a feasible tool direction computation procedure was provided based on constraint information. A manufacturability analysis tool was brought forward for mold part surface design. A mold part with sculpture surface was analyzed based on the constraints of part direction and surface machining. As a result, a feasible parting surface design could be achieved. Finally, the feasibility of the sculptured surfaces manufacturability analysis method was proved.
