Abstract
Large, non-unitarily forged shaft workpieces such as a crankshaft have successive shaft features inductively heated and forged without cool down between each sectional forging process. The temperature profile along the axial length of the next section of the shaft workpiece to be inductively heated and forged is measured prior to heating, and the induced heat energy along the axial length of the next section is dynamically adjusted responsive to the measured temperature profile to achieve a required pre-forge temperature distribution along the axial length of the next section prior to forging.
