Abstract

The present invention makes it possible to convert an NC program used for one processing into an NC program capable of securing appropriate processing accuracy in another processing machine. Provided is an NC program conversion process method by a conversion system which converts a conversion source NC program for executing a processing in a conversion source processing machine into a conversion destination NC program for executing a processing in a conversion destination processing machine, wherein an input of information relating to (1) stiffness of the conversion destination processing machine or (2) stiffness of the tool included in a conversion destination toolset is received, and on the basis of the received information relating to the stiffness, a conversion source NC program 1424 is converted into a conversion destination NC program 1425.

Claims3

Dependent claims

A nonvolatile memory storing conversion program which is executed by a conversion system, the conversion program comprising codes of:

receiving input of destination stiffness information relating to stiffness, the stiffness being at least one of:
(1) stiffness of a conversion destination processing machine or
(2) stiffness of a tool used by the conversion destination processing machine;
and
performing a conversion processing of converting a conversion source NC program to a conversion destination NC program on the basis of the destination stiffness information relating to stiffness,
wherein, the conversion destination NC program is used by the conversion destination processing machine,
wherein a conversion destination toolset is used by the conversion destination processing machine;
in the conversion processing, and on the basis of the destination stiffness information relating to stiffness, adding or updating, at least one command relative to tool diameter correction, tool length correction, a feed rate, tool wearing correction, or a cutting speed;
and
wherein the destination stiffness information relating to stiffness includes:
the stiffness of the conversion destination processing machine;
and
the stiffness of the tool used by the conversion destination processing machine.
