ABSTRACT:
A bending machine with a rotatable bending shoe for bending conduit and pipe includes a digital electronic control system with memory for providing accurate bending control and accurate repeat bending of successive conduits or pipes to substantially the same angle. A sensor is provided for determining increment degrees of rotation of a gear in the bending shoe drive train with the increments correlated to a particular degree of rotation of the bending shoe. The sensor signals are input to counting and comparator devices to terminate bending after the shoe rotates the degrees stored in memory for a particular bend.
