Research About the Method of Sensitivity Analysis and Quality Control Based on LS-SVM

摘要：

　　Focusing on the real-time quality control in machining process,sensitivity analysis method based on LS-SVM was proposed in this paper to control the quality of products.The relationship between machining quality and influence factors is built by LS-SVM(least squares support vector machine).Sensitivity and contribution rate are calculated in sensitivity analysis.The quality of products can be controlled by controllable factors according to the result of sensitivity analysis,and the control effect can be evaluated by quality loss function.The method verification was conducted by a simulation example.At the end of this paper,a case about globoidal cam was presented to verify the feasibility and accuracy.
