Abstract

Machining deformation compensation technology based on on-machine measurement (OMM) has been widely applied in the field of thin-walled parts machining. However, few research has been conducted on the calculation method of machining error for thin-walled parts. In this study, based on surface reconstruction technology of non-uniform rational B-spline (NURBS), a quick method for calculating machining error of thin-walled parts is proposed. The value of machining error is equal to the distance from the cutter location on the tool envelope to the corresponding point on the reconstructed surface. To simplify the solution process, a spatial rotation translation transformation is performed firstly on the reconstructed surface. Subsequently, we developed an iterative algorithm to efficiently locate the corresponding points on the reconstructed surface, enabling us to accurately calculate the machining error value.
