To explore its fullest machining potential, there is always a requirement to examine the effects of its varied input parameters on the responses and resolve the best parametric setting. This paper proposes parametric analysis of a WEDM process by applying non-parametric decision tree algorithm, based on a past experimental dataset. Two decision tree-based classification methods, i.e. classification and regression tree (CART) and Chi-squared automatic interaction detection (CHAID) are considered here as the data mining tools to examine the influences of six WEDM process parameters on four responses, and identify the most preferred parametric mix to help in achieving the desired response values. The developed decision trees recognize pulse-on time as the most indicative WEDM process parameter impacting almost all the responses. Furthermore, a comparative analysis on the classification performance of CART and CHAID algorithms demonstrates the superiority of CART with higher overall classification accuracy and lower prediction risk.}, title={A Data Mining Approach for Analysis of a Wire Electrical Discharge Machining Process}, URL={http://www.czasopisma.pan.pl/Content/120927/11_Chakraborty_corr.pdf}, doi={10.24425/mper.2021.138536}, keywords={wire electrical discharge machining, data mining, classification and regression tree, chi-squaredautomatic interaction detection, classification}, }
