Abstract

The point of this study is to optimize the cutting force and surface roughness during flood drilling of austenitic stainless steel AISI 316L. The trials are conducted using machining centre MAHO-DMC 835V at different levels of spindle speed (12, 18 and 24 mmin-1) and feed rate (0.025, 0.040 and 0.055 mmrev-1) based on a set of central composite design (CCD) experiments. Face centred CCD matrix generated using Design Expert software. Results were collected using kistler dynamometer and accretech handysurf surface roughness tester. Analysis and discussion are focused on the surface roughness and thrust force. Combination of lower cutting speed and lower feed using uncoated solid carbide twist drills gives best result in terms of roughness value, while lower cutting force can be gained using lower feed and high cutting speed. To estimate the cutting performance for practical applications dealing with corresponding drill bit, empirical predictive models have been proposed. The models have been assessed quantitatively and showed good agreements with the experimental data
