An optimal process determining system executes a step of calculating a temporary process that includes information of a plurality of individual processes. According to an example, each process includes a tooling including of a tool, a holder, a tool projection length, and a sequence of the plurality of individual processes. A similarity between the toolings of two individual processes is calculated. In addition, a calculation is performed relating to a plurality of integrated processes for which the tooling of one of the individual processes having a high similarity is integrated into the tooling of the other one of the individual processes. In addition, an optimal process is determined from the plurality of integrated processes on the basis of an actual machining time in each of the integrated processes, a unit integration reduction time reduced as one of the toolings of the individual processes is integrated, and the number of the individual processes integrated.

Process integration determining system and method

A machined shape determining step of determining a machined shape machined by a basic tooling or basic tooling template of each machining efficiency group from a material shape (S), a tooling determining step of determining an optimal tooling comprising a combination of a tool, a holder and a tool projection length on the basis of information of the tools and the holders, stored in a tool holder information storage unit, the combination having a maximum machining efficiency and being able to form the material shape into a corresponding one of the machined shapes without interfering with the machined shape (S), a process candidate determining step of determining an optimal process candidate using the optimal tooling of each machining efficiency group (S), and a process determining step of determining an optimal process on the basis of the optimal process candidate of each machining efficiency group (S), are executed.

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 memberdecides one or plural tool axis attitude. An interference dangerous zone deciding memberdecides 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 memberexecutes 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 memberdeciding 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.
