AI Technical Summary
Existing automated fiber placement technology lacks precise measurement methods and adaptive compensation mechanisms when faced with mold manufacturing deviations and changes in layer thickness, resulting in a gradual decrease in fiber placement accuracy and a reduction in the molding quality of composite material components.
By adopting a dry-running surveying method, the deviation data of the mold surface is collected by the displacement sensor built into the filament layup head, an error field is constructed, and a compensation model is adaptively selected based on the error field to dynamically compensate the NC code, thereby achieving accurate surveying and adaptive adjustment of the mold surface and the thickness of the laid layer.
It enables precise mapping and adaptive compensation of initial manufacturing deviations of the mold and cumulative changes in the thickness of multiple layers, thereby improving the wire laying accuracy and the molding quality of composite material components.
