Processing program creation device and processing program creation method

A processing program creation device in which a topology database generates topology data indicating a geometric relationship between surfaces or bending lines of each part of a plurality of parts stored in a processing data management database, acquires processing information including a tool name of a use tool used to perform bending processing on each bending line of a plurality of bending lines of each of the parts and a bending order in which the plurality of bending lines are subjected to the bending processing from a bending processing program stored in the processing data management database and used for the bending processing on each of the parts, and stores the processing information in association with topology data of each of the parts, the processing program creation device comprising:

• a processing information acquisition unit configured to search for a similar part with the same topology data as topology data of a processing target part from the topology database, and to acquire the processing information of the similar part;
• a tool determination unit configured to calculate a range of a tool length which is able to bend each bending line of a plurality of bending lines of the processing target part using a tool with a tool name included in the processing information acquired by the processing information acquisition unit, which does not interfere with the part, and to determine the tool with the tool name and a tool length within a range of the tool length as the use tool;
• and
• a bending processing program creation unit configured to create a bending processing program for performing the bending processing on the plurality of bending lines in a bending order included in the processing information acquired by the processing information acquisition unit using the use tool determined by the tool determination unit.
