摘要:
A method and system are disclosed for treating a press hardened part by induction heating localized areas of the part to have reduced hardness. The method and system monitor an ambient temperature, cycle time, outgoing part property requirements, and outgoing part hardness in local areas. A time value and temperature value are set by a computer system for a plurality of induction heaters. A local area of the part is induction heated to soften the part in localized areas. The hardness of the localized areas is tested after induction heating.
