ABSTRACT: The quality of product by drilling process depend on the cutting condition, like cutting speed, feeding and dept of cut. In research done to determine the value of parameters process cutting in order to minimize roundness. Parameters process which is taken in this research are cutting speed, feeding and dept of cut. The research using analysis of Varian (ANOVA) and respon surface methodology with approaching the smaller is better. Both of these analysis use to determine the value of parameters process above. The combination of parameter process value which is produce optimal response on tool modified are cutting speed 15 m/min, feeding 0.125 mm/cyc and dept of cut 8.48 mm . These parameter values wil produce roundness 64.74 µm.

Keywords : drilling proceses, roundness and tool modified
