Abstract A numeral control technoloy for machining elliptic curve features that the physical axle of the mechanical drive chain to which workpiece is installed is used as actual axle, the machine-tool parameter in control system is used as virtual axle, the circles A and B are set up on said actual axle and virtual axle, which use the center of the workpiece to be machined as circular center, and the circle A (or B) is shrinked (or enlarged) by a multiple in X (or Y) direction of actural axle to form an elliptic curve. Its advantages include less calculation, simple programming and high precision.
