Title: Methods and apparatus for evaluating tool performance

Abstract: A computer-implemented method for evaluating tool performance is described which includes maintaining tool history data in an electronic memory, updating the tool history data with tool servicing data, determining from the tool history and servicing data a predicted tool remaining useful life, and displaying the predicted useful life on a computer output device. Average tool data is compared to tool benchmark data to determine tool efficiency. Tool servicing, performance and efficiency data are maintained in a spreadsheet format. Data entered into one spreadsheet is used to update a plurality of spreadsheets. The spreadsheet format allows manufacturers to keep abreast of tool performance over time and in a plurality of locations and to anticipate tool rebuild and replacement requirements.
