Modelling and Optimization for Cutting Forces in Ultrasonic-Assisted Drilling of Soda Glass

Abstract

Ultrasonic-Assisted Drilling (UAD) is a promising technology used for machining difficult-to-cut materials. In this work, an experimental investigation and statistical analysis are used to study the characteristics UAD and conventional drilling (CD) of soda glass using diamond abrasive tools. Statistically designed experiments were conducted using cutting fluid at different levels of tool feed rate, spindle speed, and tool abrasive-concentration. The mean thrust force and moment were considered the main responses. The significant drilling factors and their interactions were identified by modelling the process parameters and the output responses. The statistical models and optimum levels are determined. The ultrasonic application showed a significant effect on reducing the feed forces and drilling moment. Spindle speed is significant factor on thrust force and moment. The models error is less that 9%.
