ANALYZING THE EFFECT OF PROCESS PARAMETERS ON THE DRILLED HOLES IN FRICTION DRILLING PROCESS USING TAGUCHI METHOD

Abstract

The main purpose of this paper is to present a study on the influence of process parameters on the friction drilling process on SS400 steel using high-speed steel drilling tools, employing the Taguchi experimental design method to determine the optimal parameter combination. The three main factors investigated are: spindle rotation speed, tool taper angle, and material thickness. Through analysis of variance (ANOVA) and signal-to-noise (S/N) ratio, the parameters signifcantly affecting the length and wall thickness of the pipe were identifed. The experimental results demonstrating that the optimal parameter combination signifcantly improves the quality of the hole profle post-drilling.
