Abstract
An electrical device for controlling the stroke length of a reciprocating tool carrier of a honing machine by controlling the stroke reversal points of the carrier includes a first compensating circuit for correcting deviations from a predetermined lower reversal point and a second compensating circuit for correcting deviations from a predetermined upper reversal point, the compensating circuits supplying respective reversal point signals to a comparator for comparison with a voltage representing the instantaneous position of the carrier along a stroke path. Each reversal-point signal is a sum of a reference signal, identifying an initial reversal point between the predetermined reversal points, and a composite signal formed as an algebraic combination of difference signals each representing the distance between the carrier and a predetermined reversal point (lower, in the case of the first compensating circuit, or upper, in the case of the second compensating circuit) upon motion reversal of the carrier during a respective reciprocation cycle thereof.
