Key techniques in simulation of machining distortion for aeronautical monolithic component;

The machining distortion by cutting is a key problem in the AUTO-machining field.

In view of the fact,to predict and control effectively their machining distortion,calculations of the milling distortion were performed for the aero-thin-walled components by the 3-D finite element method considering the milling forces,the clamping forces and the initial residual.

The model of residual stress and cutting force is built by the analysis of the residual stress and the model of cutting force,which provides an effective theoretical basis for deformation of CNC cutting.

Cutting force induced deformation during machining is critical for precision turning of low-rigidity workpieces.

This makes the MPS machine concept a very economical texturing solution for fine denier yarns.

The processing production is controls the product quality with difficulty,may carry on the control through the simulation method to its production working procedure,used the DEFORM software to carry on the finite element analysis for the big distortion production,to produced the instruction function.
