In this paper concept of implementation of the soft computing approach is introduced for the environment friendly steel hardening processing unit, i.e. for Plasma Ion Nitriding (PIN) System. In Plasma Ion Nitriding system, a proper and efficient mechanism is required to meet the problem of finding process parameters involved in the surface hardening treatment of different types of steel. The algorithmic model proposed here is meant to facilitate the prediction of values of the process parameters required to be identified for the surface hardening of the steel in the PIN system. Here, an effort has been made to provide an effective and efficient algorithmic solution model for the soft computing based Plasma Ion Nitriding system. © 2012 IEEE.
