Abstract: A system for causing proportional interpolation in a numerically controlled machine having three, or more, degrees of motion is described. Two of the degrees of motion may occur in a plane defined by perpendicular axes and can be planar or revolutional motions. These two motions would then be defined with respect to the axes and could be mathematically linear or nonlinear. The other degrees of motion can be revolutional or planar motions individually defined with respect to any of the axes of the system. The invention is directed to a system for causing all motions to be proportional to a selected one of the motions irrespective of whether the selected motion is linear or nonlinear. This is achieved by calculating proportionalities between the selected motion and the other motions and combining the calculated proportionalities with the programmed data to cause the final motion to be in accordance with the combined data.

Abstract translation: 描述了在具有三个或更多个运动程度的数控机器中进行比例插值的系统。 运动中的两个可能发生在由垂直轴限定的平面中，并且可以是平面或旋转运动。 然后这两个运动将相对于轴定义，并且可以在数学上是线性的或非线性的。 其他运动程度可以是相对于系统的任何一个轴单独定义的旋转或平面运动。 本发明涉及一种用于使所有运动与所选择的一个运动成比例的系统，而不管所选运动是线性还是非线性。 这是通过计算所选运动与其他运动之间的比例来实现的，并将计算的比例与编程数据组合以使最终运动符合组合数据。
