Abstract
Finishing allowances are given to a structure by a CAD/CAM system, and cutter path data for machining the finishing allowances are simultaneously generated. A surface finish is indicated on a die structure by a finishing mark. Finishing allowances are given to the die structure, producing a die structure with finishing allowances. Thereafter, a physical interference is confirmed on a screen image in order to generate cutter path data for a cutter head with respect to the die structure. If an interference occurs, the operator replaces a cutter with a longer cutter, and confirms again a physical interference. Cutter path data with respect to the die structure with finishing allowances can be generated substantially automatically.
Claims7
A method of generating data for designing a structure section of a structure, which comprises a product shape section and the structure section, with a computer-aided design/computer-aided manufacturing system, comprising the steps of:
- generating reference structure section data representing a positional relationship between a plurality of feature points as reference points in a reference product shape section and a predetermined location in a reference structure section;
- and
- replacing coordinates of the reference points in the reference structure section data with coordinates of feature points in new product shape data which correspond respectively to feature points in the reference product shape section, and establishing the reference structure section data after the coordinates of the reference points therein are replaced, as new structure section data when the new structure section data corresponding to new product shape data are to be generated.
