摘要
传统DDA圆弧插补方法的进给速度波动较大,误差亦较大。提出一种用高级编程语言VB实现的高效圆弧插补方法,该方法以传统DDA圆弧插补原理为基础,并对其进行改进和优化,以圆弧半径作为插补进给的依据,采用左移规格化和预先加载改善插补效果。仿真结果表明:相比传统DDA圆弧插补方法,高效圆弧插补方法不仅插补效率高,而且插补精度也有所提高。
During the process of conventional DDA arc interpolation, the synthesis feed rate fluctuations are large, the machi- ning errors are large also. A new efficient are interpolation method was proposed. In the method, the principle of DDA arc interpola- tion was used which function was optimized and improved, radius was used as the basis of interpolation feed, the left normalized data and pre-loaded were used also. The simulation resuhs show that the improved circular interpolation algorithm not only has high efficien- cy, but also has high accuracy.
