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.

Finite element method based machining simulation environment for analyzing part errors induced during milling of thin-walled components
Jitender K. Rai,Paul Xirouchakis +1 more
TL;DR: In this article, a finite element method (FEM) based milling process verification model and associated tools are presented, which by considering the effects of fixturing, operation sequence, tool path and cutting parameters simulates the milling processes in a transient 3D virtual environment and predicts the part thin wall deflections and elastic-plastic deformations during machining.

Yuwen Sun,Shanglei Jiang +1 more
TL;DR: In this article, an accurate modeling of dynamic milling system with the force-induced deformation effect is presented, where both the thin-walled part and the cutter are discretized into differential elements, such that the influences of the force induced deformation and multi-point contact structure dynamics can be simultaneously considered at the contact zones.
