System and method for heating metal blanks
Abstract:
A method of adjusting a position of a blank entering a furnace includes measuring a position of a heated blank exiting the furnace, recording one or more offset values from a nominal value of the heated blank exiting the furnace, calculating a revised position of a subsequent blank entering the furnace as a function of the one or more offset values, and adjusting a position of the subsequent blank entering the furnace as a function of the one or more offset values. The position of the heated blank exiting the furnace can be measured with an electronic vision system, a robot can adjust the position of the subsequent blank, and offset value(s) can be an elapsed furnace operation time, a number of heated blanks that have exited the furnace, and a physical dimension between an actual position of the heated blank and the nominal value of the heated blank.
