B11 Performance of Palm Oil as MQL Fluid during High Speed Drilling of Ti-6Al-4V(Advanced machining technology)

Abstract

This paper presents an experimental investigation on the performance of a synthetic ester and palm oil during high speed drilling (HSD) Ti-6Al-4V using minimal quantity of lubricant (MQL) method. Tool wear, wear mechanism, cutting forces and surface integrity were monitored during the machining trials. In order to study the ability of the cutting fluids, temperature was measured during drilling process using a thermocouple wire. Both the synthetic ester and palm oil present comparable performance in terms of tool wear. In addition, palm oil outperformed synthetic ester in terms of cutting forces and workpiece surface integrity due to its ability to reduce the temperature during the drilling process.
