METHOD AND DEVICE FOR MACHINING SIMULATION AND PROGRAM FOR ALLOWING COMPUTER TO EXECUTE THE METHOD

WIPO Patent Application WO/2010/134128

A1

Provided is a method and device for machining simulation enabling adequate detection of interference of a tool machining region with a work shape model without being influenced by the movement path of a tool and the expression precision of a shape model. A tool model setting means creates a tool shape model used for work machining and including a strict tool shape and a tool shape model used for interference check and included in the strict tool shape according to the error range set in view of the movement path of the tool and the expression precision of the shape model, creates a tool machining region shape model from the tool movement path during the machining feed and the tool shape model for work machining, removes the created tool machining region shape model from the work shape model, thereby creates a machined work shape model, creates a tool machining region shape model from the tool movement path during the fast-forward feed and the tool shape model for interference detection, and thereby detects an interference of the created tool machining region shape model with the work shape model.
