ANALYSIS OF DEFORMATION OF NON-STIFFBILLETS DEPENDING ON THE CLAMPING SCHEME AND CUTTING MODES
Abstract and keywords
Abstract (English):
Clamping of non-stiff thin-walled billets on machine tools for various machining operations is accompanied by the appearance of significant deformations in them. The new approach to the analysis of the billetdeformations from the clamping forcesis developed on the base of finite element method. The calculation error of billet fixing is estimatedon the example of a cylindrical billet. For various fixing schemes the corresponding boundary conditions are developed. The error analysis results obtained by finite element method for various fixing schemes, billet geometry and cutting modes are presented.

Keywords:
finite element method, fixing errors, ANSYS, boundary conditions.
