1. A method of heat treating a component, comprising:
- heating a first feature of the component;
heating a second feature of the component differently than the first feature;
measuring a temperature value of the first feature and of the second feature;
comparing the measured temperature values to a threshold temperature value; and
modifying the heating of at least one of the first and second features based on the comparison.

Abstract
A method of heat treating a component is disclosed. The method may heat a first feature of the component and heat a second feature of the component differently than the first feature. The method may measure a temperature value of the first feature and of the second feature. The method may also compare the measured temperature values to a threshold temperature value. The method may modify the heating of at least one of the first and second features based on the comparison.

15. A heat treatment system, comprising:
-
a power source; a heater configured to receive power from the power source to heat a component; at least one sensor configured to measure a temperature value of a first feature of the component and a temperature value of a second feature of the component; and a controller configured to receive a signal from the at least one sensor indicative of the measured temperature values of the first and second features and to modify heating of at least one of the first feature and the second feature based on the signal. - View Dependent Claims (16, 17, 18)

19. A method of heat treating a component, comprising:
-
heating a first feature and a second feature of the component using electrical heating; measuring a first temperature value of the first feature and a second temperature value of the second feature; comparing the measured first and second temperature values to a pre-heat temperature value; heating the component above a critical temperature using fuel fired furnace heating when at least the first temperature value exceeds the pre-heat temperature value; and rapidly cooling the first feature with a cooling material such that material hardening occurs in the first feature and material hardening does not occur in the second feature. - View Dependent Claims (20)
