Abstract: A controlled machine-positioning system wherein machine movement may be determined by separate drive sources, one of which is servo-controlled and directly responsive to input data, and the other being only indirectly controlled. This system is particularly useful as incorporated in numerically controlled arrangements for certain unique threadcutting operations and wherein the normal servocontrol is not wanted for a particular operating mode.
