Factors Analysis Affecting the Roughness at Side Milling

Abstract

The study deals with evaluation of side milling factors, which influence the surface roughness parameter Rz. Four factors (diameter of milling cutter, spindle speed, feed per tooth and depth of cut) which enter into technological process of side milling of slots have been evaluated by means of full factorial analysis. The surface roughness has been evaluated by static quality characteristic from the peak to valley Rz parameter. The multiple linear regression equation ob- tained after analysis of variance gives the level quality Rz as a function of the significant factors. The main effect of dif- ferent factors and their interaction significance has been found, which generated surface profile under defined conditions by side milling.
