Abstract

The QuenchMiner Expert System is an enhancement over the original Web-based Data Mining tool developed at CHTE, WPI for analysis of quenching data. The goals of this Expert System are predicting results obtained under given quenching conditions, thereby supporting decision making to improve performance. It thus assists Heat Treating users. It is fed with the knowledge an expert has in the user domain. For example, a human expert knows that higher agitation implies greater distortion tendency; cooling rate of a quenchant affects distortion more than the carbon content of the part alloy etc. These facts are converted into rules with priorities and relative weights. The Expert System uses these rules to analyze cases submitted by the user and estimates parameters of interest. The focus is on Quenching Media and Distortion Control. There is considerable use of Artificial Intelligence in QuenchMiner, primarily Rule Interpreter and Forward Chaining techniques.
