Abstract

In order to reduce the workpiece deformation in the machining process and improve the machining accuracy, this paper puts forward multi-objective fixture optimization method based on the objective function of workpiece even deformation and the minimizing machining deformation. Based on the optimized fixture layout, the method divides the processing path into a plurality of conditions and each condition uses genetic algorithm and finite element optimization algorithm to solve the optimal clamping force. In order to verify the effectiveness and the reliability of the algorithm, based on the ANSYS secondary development, this paper uses APDL to compile finite element solving model of parametric workpiece-fixture system, finally uses MATLAB language to compile the genetic algorithm program, doing simulation on the simultaneous optimization of fixture layout and the clamping force. Through the simulation calculation, this paper gets adaptive optimization curve of fixture layout and clamping force, which realizes simultaneous optimization of fixture layout and clamping force. It is an important improvement of fixture optimization method, which can greatly improve the performance of the fixture.
