This invention provides a method and apparatus for calculating grinding allowance of workpiece in laser cladding additive manufacturing. The method involves acquiring first and second point cloud data of a workpiece before and after grinding, respectively. An unground portion is identified from this data and registered to obtain a transformation matrix. Applying this matrix to the first point cloud data yields a registered third point cloud. The third and second point clouds are then projected onto respective fitting planes to generate first and second discrete projection point sets. B-spline curves are fitted to these point sets. Finally, the grinding allowance is calculated based on the distance from points on the first B-spline curve to the tangent lines at corresponding points on the second B-spline curve. This approach utilizes laser 3D measurement and point cloud registration for non-contact measurement, effectively improving workpiece quality and reducing material waste during grinding.
