Intelligent Compensation for Machining Error in the Batch Production Based on Automatic Line

Abstract

In order to improve the machining accuracy and machining efficiency of workpieces in the batch production based on automatic line, an on-line intelligent compensation system adapting to this production pattern is studied. The system takes the machining error prediction model based on support vector machine and compensation coefficient adaptive correction method as the core, and the compensation value is corrected in real time. Aiming at the automatic production of the brake disc, the intelligent compensation software for machining error is developed based on B/S architecture. On the basis of realizing the real-time acquisition of machine tool state information and error measurement data, the machining error prediction, compensation value calculation and feeding back to the machine tool are completed. The actual application results show that the qualified rate of the brake disc is improved, and the machining accuracy is guaranteed effectively.
