In a programme control system for a machine tool a digitally programmed tape 200 carries blocks of information for machining steps. Each block is read by a reader to provide information for (1) control of work-table speed, through a store B and transmission G, (2) control of the direction of travel of the table through a store C and stopcircuit P, by energizing clutches H and (3) control of the feed-rate of a saddle 30 through a comparator-selector M to energize a transmission I driving a lead-screw 36. In addition, each block of input data includes numerical information defining the end-point position to which the saddle 30 and cutting tool are translated to carry out the step. This position data is transferred from the reader A to an end position store E which is connected through digital-to-analogue converters L as an input to comparators and resolvers J wherein desired and actual end-point saddle positions are compared. The resultant error signal, through discriminators K and stop circuit O, control the drive means I and initiates the reading of the next machining step by reader A. The store E, Fig. 10 (not shown), comprises a plurality of stepping switches set in accordance with end-position information, which control the digital-to-analogue converters which encite the stators of finemedium and coarse resolvers, the rotors of which are driven through successive sets of reduction gearing from the lead-screw. The rotor voltage is fed to the discriminators K. End position adjustments are fed to a selection store F, comprising a stepping switch which selects a variable potentiometer, supplied with an alternating voltage, in adjustors Q the tapped voltage of which is summated with the discriminators K. It is stated that this adjustment is limited to approximately a quarter revolution of the fine resolver Larger adjustments are effected through the adjusters Q by (1) digital summing of the adjustment signals and the outputs of the end position store E and (2) summing of sine and cosine adjustment signals with the outputs from the digital to analogue converters L.
