A conveyor system for transporting parts through a plurality of processing areas. The conveyor system has a plurality of motor driven conveyors, each of the conveyors for transporting parts through an associated one of the processing areas. Digital motor shaft encoders are provided for monitoring the speed of the conveyor motors. Motor speed controllers are electrically coupled to the encoders and are responsive thereto, for regulating the speed of the conveyors thereby synchronizing the speed among all of the conveyors. A computer is electrically coupled to one of the motor speed controllers for providing a predetermined conveyor system speed set point. Part detectors are electrically coupled to the computer, for verifying each part's progress along each of the conveyors thereby enabling the computer to track the movement of each part transported along the conveyor system to detect part to part collisions.
