The invention relates to a three-dimension
visualization process design system and a design method thereof, belonging to the
computer integrated manufacturing field. In the invention, a three-dimension model is built on the supporting platform of a design
system CAD, and other models carry out
process design by taking the
CAD system as a support and the three-dimension model as a basis; the features of the three-dimension model are identified automatically or semi-automatically by a feature identification module; the determination of a
processing chain, the design of a clamping scheme, and the selection of a cutter and a clamp are respectively finished according to the identified features by a
processing method selecting and positioning scheme design module; the sequencing of the
processing features is finished by process sequencing; the generation of an
intermediate state model leads the
process design to be imagery and visual; the calibration of tolerance is finished by a
process dimension calculation module; and various process cards which meet the requirements are output by a process card management module. The
system and the method of the invention have the advantages of visual process design, good intelligence, high efficiency, and good quality, etc.
