Abstract:
1. A method for deflashing product from an extrusion adjustably positioned in intervening proximity between a punch and die comprising the steps of: monitoring the position of said punch, communicating the monitored position of said punch to a programmable logic controller, measuring the pressure of the punch against said extrusion at said die communicating said pressure measurement to said programmable logic controller, setting a threshold limit of allowable pressure of the punch against said extrusion at said die, controlling the extension and retraction of the punch stroke of said punch in response to said pressure measurement by commands of said programmable logic controller executed by a positioning actuator of the punch wherein if the measured pressure of the punch against said extrusion at said die is equal to or less than said threshold limit allowing the punch stroke to be completed and wherein if the measured pressure of the punch against said extrusion at said die is greater than said threshold limit retracting the punch stroke.
