Zhou-Long Li,Li-Min Zhu +1 more
TL;DR: In this article, a mathematical model and algorithm for minimizing the deformation-induced surface errors are developed through slightly optimizing the shape parameters of the tool path surface, and the results demonstrate that the surface errors mainly caused by machining deformations in flank milling of flexible blades can be largely reduced by using the developed algorithm.

Milling error prediction and compensation in machining of low-rigidity parts
TL;DR: In this paper, a new integrated methodology for modelling and prediction of surface errors caused by deflection during machining of low-rigidity components is proposed. But this approach is based on identifying and modelling key processing characteristics that influence part deflection, predicting the workpiece deflection through an adaptive flexible theoretical force-FEA deflection model and providing an input for downstream decision making on error compensation.

Error compensation strategy in milling flexible thin-wall parts
TL;DR: In this paper, an advanced error prediction and compensation strategy specifically focused on force-induced errors in machining of thin-wall structures was proposed, where the machining error is predicted using a theoretical flexible force-deflection model and compensated for by optimising the tool path prior to machining.
