Machining simulation apparatus

Abstract

A machining simulation apparatus (1) includes a model storage (4) for storing information about machining models (11) that define mechanical elements, such as spindle heads and tables, jig models (12) that define jigs, such as chucks and holders, material models (13) that defines the shapes of workpieces, and tool models (14) that defines the shapes of tools for machining the workpieces. Each tool model comprises a machining tool model (14A) and an interference check tool model (14B). A material model is machined with the machining tool model (14A) according to an axis movement command for cutting feed so as to update the shape of the material model. Subsequently, interference of the interference check tool model with the material model, jig models, and machine models are checked for according to an axis movement command for rapid traverse.

Description

technical field [0001] The present invention relates to a processing simulation device which simulates cutting of a material model using a tool model and checks the tool model by controlling the relative positions of the tool model and the material model according to an NC program and / or a manually operated axis movement command Interference with the material model. Background technique [0002] A typical conventional machining simulation device adopts a single tool model to excise a part of the material model, and checks the interference between the tool model and the material model. In other words, this type of equipment controls the relative positions of the tool model and the material model according to the axis movement command, so that if the axis movement command is a cutting feed command, the area where the tool model and the material model overlap each other is taken as the cutting area from the material model. Removed, and if the axis running command is a fast tra...
