Abstract Hybrid machining is a combination of conventional with the non-conventional process or two non-conventional processes. In the present work, an attempt has been made to combine hot air with a conventional cutting tool to form a novel Hot Air Assisted Hybrid Machining (HAAHM) for the machining of soda-lime-silica glass. The mathematical model for the Material Removal Rate (MRR) and Surface Roughness (Ra) using Regression Analysis (RA) and the Artificial Neural Network (ANN) models has been developed for the grooving process. The deviation of 8.24% and 7.70% were found in the prediction of MRR and Ra by regression analysis and the deviation of 1.89% and 1.70% for MRR and Ra using an artificial neural network model. The deviation between the predicted and the experimental results of both the models are found to be within the permissible limit. Higher predictive capabilities were observed in ANN model than the regression model. However, both models demonstrated good agreement with the MRR of soda-lime-silica glass by this hybrid machining process. Keywords Artificial neural network (ANN) . Regression analysis (RA) .

1 Introduction Soda-lime-silica glass is the most pervasive kind of glass widely used in major structural materials such as windowpanes and glass compartments, jugs and containers, optical, biochemical and electrical and electronic devices because of the wear resistance, low thermal and electrical conductivity, high strength, lightweight, hardness, high chemical and heat resistance [1]. The soda-lime-silica glass is moderately economical, chemically stable, and sensibly hard with maximum workability. The resoftening and remelting characteristics of the soda-lime-silica glass make it ideal for recycling. Hence,

Soda-lime-silica glass accounts for more than 92% utilization among all the different types of manufactured glasses. The main composition of the soda-lime-silica glass is Silicon dioxide (SiO2) that increases the resistance to thermal shocks, Sodium Carbonate (Na2CO3) for lowering the glass transition temperature and Calcium Oxide (CaO) for high chemical stability. The stability of the soda-lime-silicate glass is increased by adding Magnesium Oxide (MgO) and Aluminum Oxide (Al2O3). The high brittleness characteristic of the
