Abstract: The machining deformation and vibration of thin-walled parts due to inherent weak rigidity greatly affect the final quality of products. Reasonable clamping can control the machining deformation and vibration, improve the machining stability of thin-walled parts effectively. With the development of new sensing and control algorithms, modern fixtures are gradually developing towards the direction of intelligence. Intelligent fixtures integrated clamping force control, deformation compensation, real-time monitoring, dynamic feedback adjustment and other functions have emerged and became new research hotspot in academia and industry. Therefore, the clamping scheme optimization method and machining auxiliary support technology of thin-walled parts is combed in this paper. The current research status at home and abroad about system architecture, specific application and control strategy of intelligent fixture are also reviewed systematically. Ultimately, the extant problems in clamping scheme optimization and intelligent fixture are concluded and the potential development trends are proposed.

Key words: thin-wall parts, clamping optimization, auxiliary support, intelligent fixture
