ABSTRACT:
An apparatus for controlling the length of movement of a controlled member along a path of repeated operating positions. The apparatus comprises a function generator with an axis digital integrator for each axis of movement of the controlled member and a resultant length of movement digital integrator. All digital integrators have the same input iterate rate. By initially setting the integrand of the resultant length of movement integrator to the square root of the sum of the squares of the initial integrand values of the axis digital integrators of the function generator, the output of the resultant length of movement digital integrator is proportional to the resultant of the distances commanded along the axes by the axis integrators of the function generator. A counter is set to the incremental distance between repeated operating positions and is counted down by the output of the resultant length of movement digital integrator. The controlled member is stopped when the incremental distance between repeated operating positions has been reached. After the work is completed at the operating position the counter is again set to the incremental distance between operating positions and the controlled member is moved to the next operating position.
