METHOD AND SYSTEM FOR DESIGNING A CUTTING TOOL

摘要

A method of designing a cutting tool uses finite element numerical models (14) to predict a response of the tool during a simulated cutting operation on a workpiece, and to simulate a chip-flow phenomenon occurring during the cutting operation. The chip-flow model (14) incorporates representations of a fracture mechanism describing a chip separation phenomenon, a heat-generating mechanism describing a thermal coupling phenomenon, and a shear localization mechanism describing a shearing phenomenon wherein these phenomena occur during the cutting operation. The predicted tool response and the chip-flow simulation are evaluated by an artificial intelligence system (18) to render rule-based judgments which are embodied in recommendations for continuously modifying the models (14) and input design variables until the simulation and response converge to an optimal result.
