Summary:An indexing control system for a rotatable turret punching press where tool stations have different indexing distances therebetween and a read only memory stores the number of indexing pulses required to index between each pair of adjacent stations. A position register functions to provide a present position value at the beginning of each indexing operation and also serves to control readout from the memory of the number of indexing pulses required to execute a new command. The total number of indexing pulses required for indexing movement in a given direction may be accumulated and then used to control the actual indexing movement of the turret (and also the direction of indexing movement, if desired).
