Abstract
An effective method to investigate the causality model in 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 in this report as the concrete application of this system. Several hardness estimation models are implemented by composing and utilizing small and simple program modules. These modules are evaluated in this system which utilizes data base and corrected by steps. This process is very effectively executed in this system. The most suitable model that has been evaluated by the above method can be applied to the hardness estimation in the wide range of condition.
For the verification, automatic condition setting is done. The estimated results closely correspond to the experimental results (hardness distribution) under the setting conditions.
