Work simulation device and method

Abstract

Provided is a work simulation device, comprising: a local region setting unit (26) which sets a local region in a workpiece; an offset transform processing unit (4) which offset transforms, among a workpiece overall 3-D shape model (12), a shape of a portion wherein a local region is set, generating a workpiece local 3-D shape model (13); a local tool movement data output unit (6) which outputs local tool movement data (17) from overall tool movement data (16) based on a tool model (15) and tool movement trajectory data; a local cutting transform processing unit (8) which carries out a cutting transformation of the workpiece local 3-D shape model (13) on the basis of the local tool movement data (17); and a display superposition unit (11) which superpositions the cutting transformed workpiece local 3-D shape model (13) upon the workpiece overall 3-D shape model (12) and displays same.

Description

technical field [0001] The present invention relates to cutting processing using an NC (Numerical Control: numerical control) machine tool, and to a processing simulation device and method for converting the shape of a workpiece (processed object) represented by a three-dimensional shape model according to a tool model and its movement trajectory To perform cutting deformation, and display the resulting shape graphically, thereby simulating the cutting process of the workpiece on the computer. Background technique [0002] When cutting using an NC machine tool, machining simulation is widely used to verify whether a desired shape can be machined correctly using a prepared NC program. However, in the case of performing machining simulation to find out problematic points in machining, there may often arise a problem that machining simulation must be repeatedly executed in order to analyze the cause or take countermeasures. [0003] In the cutting process, the workpiece starts...

Problems solved by technology

However, in the case of performing machining simulation to find out problematic points in machining, there may often arise a problem that machining simulation must be repeatedly performed in order to analyze its cause or take countermeasures

Therefore, for example, in the case where the found problem part occurs near the end of processing, it takes a long time to wait until the part can be confirmed, and it becomes a problem that efficient verification work cannot be performed.
