This study was conducted to improve the machining dynamics structure when machining the SKD11 hard steel using a flexible-fixture system to reduce cutting forces and vibrations, especially in the start cutting and exit cutting stages. In experimental processes, with the application of a flexible-fixture system, the average cutting force and vibration amplitudes were reduced by 9.35% and 15.13%, respectively, while maintaining good stable states during the entire machining process. This designed flexible-fixture can dynamically adjust the structure parameters of the dynamic system and can be used to improve the machining dynamics of milling process to improve productivity and quality during the machining process.

This designed flexible-fixture can dynamically adjust the structure parameters of the dynamic system and can be used to improve the machining dynamics of milling process to improve productivity and quality during the machining process.
