ABSTRACT:
A numerical control apparatus for controlling a machine which includes a movable element and a servomotor for moving the element. The numerical control apparatus includes memory means for storing numerical data representing parameters such as amount and rate of movement of the element. The numerical data are expressed either or both in a first and second system of measurement. Codes are stored in the memory means for some of the numerical data which are expressed in the first system to define basic movements of the element. The numerical control apparatus is settable to be operable for data expressed in either the first or second system of measurement. The numerical data expressed in the second system of measurement are automatically converted into the first system when the numerical control apparatus is set to be operable for data expressed in the second system of measurement.
