308 フィクスチュアリングフィーチャに基づく工作物最適クランプ位置の決定 : フィクスチュアリングフィーチャの概念と 2 次元モデルへの適用

Abstract

In the manufacturing process, engineers often estimate the deformation of clamped workpieces from their features, and select clamping points with minimum deformation. In this paper, the fixturing features which composed of the form features, the compliance features and deformation features are proposed in order to determine the optimum points for clamping a workpiece. And the effects of the method of deciding the best clamping points applying this concept are confirmed for two-dimensional workpieces.
