A circuit particularly useful for automating a standard machine-shop turret lathe. The circuit includes the capability of programming a sequence of events to be performed by the lathe. Mechanical actuators such as electrical motors and pneumatic pistons provide the capability of imparting movement to those lathe mechanisms usually operated manually. The operations of these lathe mechanisms are monitored by sensors such as photocells and microswitches. Pulses produced by the sensors are routed through the circuitry in a prescribed manner to produce the desired sequence of events.
