摘　　要：为提高数控机床的运动稳定性和加工效率,首先分析了直接转接算法的原理和存在的问题,然后对圆弧过渡算法的数学模型和圆弧参数计算方法等进行了研究,并由此推导了圆弧转接位置处最大进给速度的计算公式。针对不同转折角情况下,采用直接过渡法和圆弧过渡法时可实现的最大转接速度进行了计算和对比,结果表明:圆弧过渡算法可有效提高机床加工效率,同时保证运动过程的平稳性,适用于现代高速、高精度机床控制系统。In order to improve the stability and efficiency of NC machine tool,the principle of direct transfer algorithm and the existing problems were analyzed,then the mathematical model of the circular arc transition algorithm and parameter calculation method were studied,and the formula of the arc switching position the maximum feed rate.Under different turning angle,the maximum transfer speed direct transition method and arc transition method can be calculated and compared.The results show that the arc transition algorithm can effectively improve the machining efficiency,and ensure the smooth movement of the process,suitable for modern high speed and high precision machine tool control system.
