Machining Process for a Thin-Walled Workpiece Using On-Machine Measurement of the Workpiece Compliance

International Journal of Automation Technology, 2019
Demand for highly productive machining of thin-walled workpieces has been growing in the aerospace industry. Workpiece vibration is a critical issue that could limit the productivity of such machining processes. This study proposes a machining process for thin-walled workpieces that aims to reduce the workpiece vibration during the machining process ...
