| The aim of this work was to design blade NC shot peening strengthening path, improve the accuracy of peen forming and generate CNC codes. For the 3D model of the engine blade, the paper planned the path of shot peening strengthening by section analysis method, defined shot peening parameters according the feature of blade surface, analyzed the mechanism of WBM NC shot peening, and established the calculation method of inverse solution for equipment control code by the nozzle path point and injection direction. The paper provided available pre-processing and post processing methods for the blade NC shot peening strengthening machine and developed the corresponding matching software. It was proven to be a practicable method for actual production of parts as supported by example validation in WBM CNC peening machine, which provides technical support for improving the accuracy and efficiency of blade NC shot peening. |
