Optimization of Machining Fixture Layout for Thin Walled Component using DOE and FEM

Abstract

Machining fixtures are used to improve the productivity and quality of the finished components. It is essential to produce a component in specified accuracy and quality; this can be achieved by optimizing the precise fixture design based on workpiece geometry and machining parameters.  In this work, optimum fixture layout is developed for thin walled component.  Taguchi and Response surface methodology based optimization procedures are established for identifying the optimum fixture layout.  Finite element solver ANSYS is used for predicting the workpiece elastic deformation caused by machining and clamping forces.
