Abstract

A processing program generation method for generating a processing program (PR) for a work machine on the basis of use-results information for a tool (4) attached to a work machine (2), wherein the use-results information for each part of the tool (4) is obtained, a target use part of the tool (4) is set on the basis of the obtained use-results information, and the processing program (PR) is generated in a manner such that a workpiece (W) is processed using the set target use part of the tool (4).

Claims

1. A processing program generation method for generating a processing program of a machine tool based on usage history information of a tool which is attached to a machine tool, the method comprising the steps of:

acquiring usage history information of each portion of the tool;

setting a target portion for use of the tool based on the usage history information acquired at the acquiring step; and

generating the processing program so as to machine a workpiece by using the target portion for use of the tool set at the setting step.

2. The processing program generation method of claim 1, further comprising a step of displaying the usage history information of each portion of the tool acquired at the acquiring step.

3. The processing program generation method of claim 1, wherein the target portion for use of the tool set at the setting step is an unused portion of the tool.

4. A processing program generation device for generating a processing program of a machine tool based on usage history information of a tool which is attached to a machine tool, the device comprising:

an information acquisition part which acquires usage history information of each portion of the tool;

a display unit which displays usage history information of each portion of the tool acquired at the information acquisition part;

an input unit to which a target portion for use of the tool is input; and

a program generating part which writes the processing program by using the target portion for use of the tool input at the input unit so as to machine a workpiece.

5. A processing program generation device for generating a processing program of a machine tool based on usage history information of a tool which is attached to a machine tool, the device comprising:

an information acquisition part which acquires usage history information of each portion of the tool;

a setting part which set a target portion for use of the tool by using usage history information acquired at the information acquisition part; and

a program generating part which writes the processing program so as to machine the workpiece by using the target portion for use of the tool set at the setting part.
