摘　　要：在圆弧逐点比较插补算法的基础上提出了一种适用于经济型数控机床的椭圆逐点比较插补算法.该算法对一般的逐点比较法进行了改进,在插补过程中只进行整数的加、减法运算,减少了数据的处理时间,解决了终点判别问题和自动过象限问题.The ellipse interpolation which is suitable for the economic NC machine is proposed in the paper based on the circular arcs interpolation. The new method has some improvement on general interpolation way. Through the improvement, the time to deal with data is shorter than before. Also the end point distinction and the automatic quadrant problem are solved.

关 键 词：逐点比较法 椭圆插补 象限
