Abstract
This study proposes a high precision machining method of near-net-shaped blade based on multi-process machining errors data flow control. The multi-process machining geometric error and mechanical models of the blade multi-process are firstly constructed. The stiffness of blade-fixture system is secondly analyzed. The machining error flow of the blade multi-process is finally controlled by the adaptive CNC machining process under the sufficient stiffness of blade-fixture system. The results show that the dynamic displacement response of the blade multi-process is controlled within 0.007 mm. The optimized adaptive CNC machining process of the multi-process geometric machining error data flow control can realize the high-precision manufacturing of blade.
