Abstract: Friction drilling is the process wherein the bushings are formed in the sheet materials by the frictional heat generated between rotating conical tool and workpiece. The bushings are used for threaded connections or as bearing sleeves. The present study explores the application of standard geometry tungsten carbide friction drill tool on AISI 1015. The input parameters material thickness to tool diameter ratio (T/D ratio), spindle speed, feed have been varied to study the effect on the response variables maximum thrust force, maximum torque during the friction drilling cycle and surface roughness of the friction drilled holes. The analyses of the responses have been carried out using the analysis of variance and Taguchi methods. In an attempt to understand the relationship between process parameters and response variables the mathematical modelling using the regression has been proposed.
