Abstract
Green sand molding is a commonly used casting technique for manufacturing steel castings. However, defects prevention and monitoring is an issue on which research is advancing continuously. The aim of this research work is to develop an expert system using C++. This system identifies the optimum input parameters, namely permeability, pouring temperature and green strength of the sand in order to give lower probability of defects. The defects used in this work are scabbing, sand fusion and blowholes. Experimental data from a foundry were collected for a period of 1 month with variations in the input parameters and analyzed for ranges of parameters in which defects are low. A rule-based expert system was written using CLIPS 2004, an expert system tool, wherein programming can be done using C++. The expert system so developed was used to predict the probability of occurrence of defects. Validation has to be done with more experimental work to fine-tune the expert system.
