A disclosed method utilizes virtual representations of gear profiles produced in view of accuracies and capabilities of specific machine and tool combinations to validate profile finishing parameters. The virtual representations are utilized to identify modifications needed to account for process capability and are implemented into the process to change the nominal profile utilized for producing the finished gear profiles. The resulting nominal gear profile accounts for process variations and thereby provides a more accurate and repeatable gear tooth profile.

A tool management system includes a tool management device and an information input and output terminal. The tool management device manages an assembled tool including a tool holder and a cutting tool mounted on the tool holder. The information input and output terminal is configured to input and output data to/from the tool management device. The tool management device includes a tool information database and a data retrieval unit. 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.
