Abstract
Short parts are detected on machines where bar stock is fed through one or more work spindles and held in a burring spindle during cut off. The burring spindle contains a sensing rod biased towards the front of the burring spindle and adapted to contact a finished part on the end of the bar stock as the burring spindle moves on to the stock if the part has the proper length. This moves the sensing rod back, with respect to the burring spindle, and a target on the end of the sensing rod enters the sensing field of a proximity sensor. If the burring spindle moves onto a short part, the sensing rod is not moved by the design amount and the target disc does not enter the sensing field of the proximity sensor. The sensor then initiates a short part signal.
