A template controlled machine tool, especially for machining the crankpins of crankshafts. A first template member rotates in unison with a crankshaft mounted on the work axis of the machine. A second template member is mounted on a carriage so that the second template member and carriage are actuated when the first template member rotates. The machine tool has a work carriage on which a tool is mounted. The work carriage is driven by a motor which receives power from an electric circuit that is controlled in conformity with the movement of the template carriage. Each of the carriages actuates a digital measuring device and a comparator compares the pulses therefrom and adjusts the speed of movement of the tool carriage to maintain the tool carriage position in close conformity with that of the template carriage.
An electric copying control device in a completely separate unit for crankshaft cutting machines including a cutting carriage working with a coordinate relative to a workpiece spindle and with which a template carriage follows a template driven by way of a workpiece spindle motor, whereby the template carriage drives means for regulation of speed of feed drive and additionally means are provided for control of position of the cutting carriage relative to the template carriage, the improvement of combination therewith which comprises:
