Patent ID: 8200360

Claim:
A machining parameter optimizing apparatus optimizing a machining parameter relating to at least a tool axis attitude, a machining zone and a tooling, the apparatus including a controller including a processor, the processor executing instructions stored in a memory, and configured to execute: a tool axis attitude deciding to decide said one or plural tool axis attitude; an interference dangerous zone deciding to decide, as an interference dangerous zone, a zone possible to interfere between a tool or a tool holder and a workpiece during machining by said decided tool axis attitude; a virtual tool holder generating to generate a machining simulation based on said interference dangerous zone by said decided tool axis attitude and to decide said machining zone in a way of avoiding said interference dangerous zone to generate said virtual tool holder in which there is no any said interference; and a tooling deciding to decide said tooling included in a range of a profile of said virtual tool holder, wherein said tooling is a combination of said tool and tool holder having the highest stiffness.
