Positioning Error Compensation for Machining Center by Support Vector Regression

摘要：

　　To improve the positioning accuracy of a certain type of bridge gantry machining center,a positioning error compensation method based on support vector regression (SVR) is presented.After analyzing the influence of training data sets distribution,and pointing out that SVR may have a substandard performance when the training data are distributed sparsely at neighborhood of outliers or distributed in a small range,a training data sets constructing criterion is proposed.SVR is employed in position error compensation of a bridge gantry machining center to establish the model of the positioning error,actual positioning error compensation effects shows that the positioning accuracy and compensation operating efficiency are improved effectively.
