Outline of Final Research Achievements |
Motion accuracy of a machine tool can be significantly influenced by thermal deformation or the "aging." The objective of this project is to propose a "self-optimization" methodology for a machine tool, such that it can periodically calibrate its own motion errors and then compensate for them in a fully automated manner. The machine's motion errors are calibrated in exactly the same thermal conditions as in actual machining processes. To this "self-optimization" method, the project proposed the application of a non-contact laser barrier tool measurement system, which is widely accepted in the manufacturing industry.
