A method of designing a cutting tool uses finite element numerical models 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 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 to render rule-based judgments which are embodied in recommendations for continuously modifying the models and input design variables until the simulation and response converge to an optimal result.

Method and system for designing a cutting tool

A method for making a compact for a densified cutting insert, an easily machinable material is cut to the desired form, a plastic molding material having specific properties is contacted with the shaped machinable material, hardened to form a mold, and the resulting mold is used to form a compact for a cutting insert having the desired configuration which compact may be subsequently densified.

Method of making cutting insert

A polygonal indexable cutting insert has a chip breaker with a backwall having a main portion spaced from the cutting edge and including a plurality lands as to deflect chips in a direction toward the center of the insert.

Polygonal cutting insert

A polygonal indexable cutting insert has a chip breaker with a backwall arranged in a sinuous path with the portion approaching the corner having a shallower slope than the main portion.
