A dynamical tool adjustment method for computer numerical control abrasive belt grinding

Abstract

Blisk, as the key component in the aero-engine, is hard to be fabricated for the complexity geometry in comparison with separable impeller. In the process, cutter interference is easy to occur because of the narrow groove between adjacent blades. To solve this problem, the paper proposed a dynamic adjustment method for the cutter, through which a cutter interference can be avoided dynamically realized when the cutter approach to the potential interference zone and a smooth transition between two adjacent cutter traces can be realized instantly. Finally, with the proposed method, a polish experiment is conducted, showing its effectiveness in improving the precise and reducing the roughness.
