Abstract
A CAD/CAM system arranged so that a re-creation processing for a cutter path is automatically executed by a CAM system when a curved surface is modified by a CAD system. Functions for the cutter path re-creation processing are provided by utilizing a customizing function of the CAD system. In executing computation for the cutter path and in originating NC data, references for assigning the functions are previously set for the curved surface. When the shape of the curved surface is modified on the CAD side after the NC data has been created, the CAM is invoked to invoke the aforesaid functions. Perceiving this invocation, the CAM executes the cutter path re-creation processing by using machining condition data set for the unmodified curved surface, on the basis of the invoked functions. Thus, the cutter path for the modified curved surface is created immediately by the CAM when the curved surface is modified by the CAD.
