Abstract
This paper presents an experimental study on how to enhance the machining processes of the AISI H13 hot work tool steel by implementing a decent cooling and lubrication technic throughout the machining processes. Proper machining conditions and parameters for industrial applications are analysed namely; dry conditions, wet conditions of Boron and nano additive solutions. The flow rate is measured and calculated. The cutting fluid in different concentration is used in the hard-turning experiments. Different cutting speeds (100,150,200m/min), feed rates (0.03, 0.06, 0.09mm/rev), and a constant depth of cut (0.2mm) are considered. The assessments are equated against the machining forces and temperatures, using 12 pieces of PVD coated ceramic type turning insert-cutting tools. The results of experimental investigation show that the wet machining conditions have substantial effects across all the machining standards. It is indicated that the machining temperature is reduced tremendously during the both cases of wet machining conditions. Thus, wet machining by adding additives demonstrats enhanced machining conditions at the medium feed rates and lower cutting speeds by reducing the cutting force, which is a threat to the tool life.
