Machining parameter optimizing apparatus, method for optimizing machining parameter and program therefor

摘要

It is an object of the present invention to provide a machining parameter optimizing apparatus deciding a tool axis attitude and a machining zone and deciding a tooling having high stiffness for any profile of a finished workpiece. A tool axis attitude deciding member 21 decides one or plural tool axis attitude. An interference dangerous zone deciding member 23 decides as an interference dangerous zone a zone possible to interfere between a tool or a tool holder and a workpiece during machining by the decided tool axis attitude. A machining simulation member 25 executes a machining simulation based on the interference dangerous zone by the decided tool axis attitude and generates the virtual tool holder in which there is no any interference, and also decides a machining zone in a way of avoiding the interference dangerous zone. A non-interference tooling deciding member 27 deciding the tooling included in a range of a profile of the virtual tool holder, the tooling is a combination of the tool and the tool holder having the highest stiffness.
