Outline of Final Research Achievements

The objective of this research is to investigate a framework and basic technologies to achieve accuracy assured machining (AAM). High-speed on-machine shape measurement and estimation of error source are two important problems. For the shape measurement, a method to improve the line-laser displacement sensor has been investigated. An adaptive calibration method which utilize measurement of known shapes has been developed. For the semi-flat shape workpiece, proposed method can improve the measurement accuracy. Concerning the error source estimation, fundamental simulation methods for geometric error and mechanical error have been developed and experimentally evaluated. Except the some cases, estimation of each error factor is possible. Therefore, it can be said that basic method to decompose measured machining error into combination of prepared error sources is feasible. Based on the methods above mentioned, the feasibility of the proposed AAM framework has been confirmed.
