Tool management system and tool management device

A tool management system comprising:

• a tool management device that manages an assembled tool including a tool holder and a cutting tool mounted on the tool holder;
• and
• an information input and output terminal configured to input and output data to/from the tool management device, wherein
• the tool management device includes:
• a tool information database that stores at least:
• a tool holder ID as unique identification information directly attached to the tool holder;
• tool holder information as information relating to the tool holder;
• an assembled tool ID as unique identification information of the assembled tool;
• machine information as information relating to a machine tool that uses the assembled tool;
• workpiece information as information relating to a workpiece that has been machined using the assembled tool;
• cutting tool information as information relating to the cutting tool;
• a projection amount of the cutting tool from the tool holder in the assembled tool;
• and an assembled tool state flag turned ON when the cutting tool is mounted on the tool holder and turned OFF when the cutting tool is removed;
• an assembled tool ID generation unit that generates the assembled tool ID in a record including the tool holder ID in the tool information database when the cutting tool is mounted on the tool holder;
• a data retrieval unit that retrieves necessary information from the tool information database;
• and
• an assembled tool determination unit that determines whether the tool holder is holding the cutting tool or not, wherein
• the information input and output terminal includes an input unit for the tool holder ID,
• the assembled tool determination unit determines that the tool holder is holding the cutting tool when the tool holder ID is input by the input unit with the assembled tool state flag being in an ON state, and determines that the tool holder is not holding the cutting tool when the tool holder ID is input by the input unit with the assembled tool state flag being in an OFF state, and
• the data retrieval unit retrieves the assembled tool ID including the input tool holder ID to make information relating to the same assembled tool referable when the assembled tool determination unit has determined that the tool holder is holding the cutting tool, and retrieves the input tool holder ID to make information relating to the same tool holder referable when the assembled tool determination unit has determined that the tool holder is not holding the cutting tool.
