Abstract

PURPOSE:To improve the working accuracy of an object to be worked by correcting the level of backlash generated in proportion to the speed of revolution of driving and driven gears when both gears are reversed. CONSTITUTION:When gears are rotated by cut feeding, reversed by quick feeding and then reversed again by the cut feeding, a flip-flop 14 is reset by a discrimination circuit 12 and control circuit 13 at the time of switching from the cut feeding to the fast forwarding and the level of backlash is corrected by a set level of a storage device 16. At the time of switching from the fast forwarding to the cut feeding, the flip-flop 14 is set up by the discrimination circuit 11 and the control circuit 13 and the level of backlash is corrected by a set level of a storage device 15.
