A topology database generates topology data of a plurality of parts. The topology database acquires processing information including a tool name of a use tool and a processing order from a bending processing program of each part, and stores the processing information in association with the topology data. A processing information acquisition unit searches for a similar part with the same topology data as topology data of a processing target part, and acquires the processing information of the similar part. A tool determination unit calculates a range of a tool length which is able to bend each bending line using a tool with a tool name included in the processing information and which does not interfere with the part, and determines the tool with the tool name and a tool length within a range of the tool length as the use tool.
