精铸航空叶片型面余量双目视觉测量与砂带磨削轨迹规划
Binocular vision measurement of surface profile allowance and belt grinding path planning for precision cast aeroengine blades
摘要
Abstract
To accurately plan the targert grinding region for investment-cast blades,this paper proposes a binocular-vision-based grinding allowance analysis and trajectory planning framework.First,a binocular vision system acquires the high-density 3D point cloud of the blade to achieve rapid geometric acqisition.Then,full-profile registration is performed using cross-sectional sampling data to ensure the optimal distribution of machining allowance.Next,grinding trajectories are systematically planned based on the allowance distribution to ensure precise and selective material removal in the target regions.Finally,experimental validation is conducted on a representative investment-cast blade using abrasive-belt grinding.A coordinate measuring machine quantitatively evaluates the blade geometry before and after grinding.Experimental results demonstrate the contour dimensional accuracy of the ground regions is controlled within0.04 mm,with deviations falling within the-0.05 mm to+0.08 mm tolerance range specified by the process requirements.关键词
