摘要
Abstract
In consideration of improving the machining tolerance accuracy and reliability of ve locity control,the linear continuous machining ve locity is optimized via the Look Ahead and Back Tracking algorithms.According to the maximum acceleration allowed by the machine tool and the angle of two adjacent lines the transition velocity and acceleration was proposed.Should the hard ware condition of the computer be met,the Back Tracking is ended.Considering the real-time de mand of CNC system,the interpolation is integrat ed in the Look Ahead algorithm.The simulation and analysis of the algorithmstructure and process using C+ + and Matlab helpsbetter evaluate the algorithms.关键词
