摘要：

This paper presents a model for the synthesis of the fixturing configuration in pin-array type flexible machining fixtures. These fixtures possess an array of pins that hold parts by conforming to their shape. The proposed algorithm aims to achieve a specified level of fixture-workpiece conformability and stable equilibrium while keeping the workpiece rigid body motion due to fixture elastic deformation at or below a user-specified value. Specifically, the model finds the minimum clamping loads and the optimal number, position and dimensions of the pins necessary to achieve the conformability and stiffness goals for a workpiece having an arbitrary geometry and subjected to quasi-static machining/assembly forces. Experimental data for the X-clamp(R) flexible pin-array vise is used to validate the proposed synthesis model. (C) 2002 Elsevier Science Ltd. All rights reserved.
