Abstract

This study presents tool wear characterization of carbide cutting tool inserts in a single point turning operation of AISI D2 steel. An experiment was conducted in a 20 set of experiment matrix of cutting speed, depth of cut and feed rate and performed on a CNC lathe without coolant. Surface roughness was measured by Mitutoyo profilometer (SJ-301) and flank wear was measured by Axioskop 40. The data was compiled into Design Expert 7 software for analysis. From the result, depth of cut was found to be the main factor to have significant result on surface roughness followed by cutting speed and feed rate. No interaction between the factors was found to give significant effect to surface roughness. The most significant factor for the flank wear is the feed rate while the other two factors did not affected the flank wear. Interaction between depth of cut and feed rate was found to be the factors affected the flank wear. At the end of this study, optimization was made to produce minimum surface roughness and to produce minimum flank wear by suggesting the most suitable sets of parameter settings. Suggestion for both output response was also obtained from the optimization.
