ABSTRACT:
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.
