The effective method to investigate the interaction model in the heat processing is discussed. The computer processing system in this method consists of the data base and several peripheral modules.
The hardness estimation of CO2 laser surface hardening is carried out as the concrete application of this system. The automatic evaluation of the hardness estimation models is discussed. These models are implemented by composing and utilizing small and simple program modules which are evaluated automatically and improved by steps. This process is very effectively executed in the whole system. The most suitable model that has been evaluated by the above method can be applied to the hardness estimation within the wide range of condition.
For the verification, the automatic condition setting is done. The estimated results of the set condition closely correspond to the experimental surface hardened results.
