A fuzzy approach for induction hardening parameters selection

In this study, department of case hardness is controlled by using certain parameters which are optimized by fuzzy logic determining certain parameters of induction surface hardening. Many parameters influence hardness depth such as coil dimensions, electrical voltage and current, material type, cooling rate, etc. All parameters effecting to the induction hardening are fuzzified. Base width of the membership function for certain parameters is selected from experience of experts. Optimized fuzzy solution of the induction hardening is compared with experimental results and discussed with effects of fuzzy logic solution to the case hardening.
