Abstract:
A method for discriminating process temperature measurements used to predict a part temperature profile applied to a part in a thermal processor, said thermal processor having a correlation for predicting said part temperature profile, a plurality of zones and a plurality of temperature measuring devices disposed along said plurality of zones, said method comprising:conveying the part into and out of the thermal processor through the plurality of zones for thermal processing within a time period; measuring a process temperature during said time period by a temperature measuring device within the plurality of temperature measuring devices, said process temperature being aggregated to a plurality of process temperatures to form a process temperature profile; calculating a difference between a maximum value and a minimum value within said process temperature profile; comparing said difference to a qualifier value, assigning a logical value to a first value if said difference exceeds said qualifier value; and disregarding said process temperature for inclusion in said process temperature profile by the corrector if said logical value equals said first value.
