Improvement of Product Quality through Optimum Fixture Design 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 condition. In this work, optimum fixture layouts were developed for rigid body component. Design of Experiment based optimization procedure is established for identify the optimum fixture design. Finite element software ANSYS is used for predicting the workpiece elastic deformation caused by machining and clamping forces.
