| Outline of Final Research Achievements |
In press forming, ultrasonic measurement was applied to the detecting of product defects and the evaluation of tribological conditions in the contact interface between the tool and workpiece. A main defect, i.e., wrinkling was estimated during the press operation. The ultrasonic reflection was influenced by wrinkling. The tribological conditions were evaluated using the ultrasonic measurement based on presented contact models. Obtained results are useful for the sophistication of the in-process inspection of defects and the advancement of in-process measurement of tribological conditions.
