in this study effect of cutting parameters on thrust force, surface roughness and circularity are investigatedduring drilling of INCONEL 625 on VMC. For experiment cutting speed (10m/min,12.5 m/min and 17.5 m/min), feed rate(0.05 mm/rev, 0.075mm/rev and 0.1 mm/rev) and different twist drill(HSS, Uncoated solid carbide tool and TiAlN coatedsolid carbide tool) of 5mm diameter are used as parameter. For experiments full factorial experimental design is used.ANOVA is employed to determine most significant control factor affecting the thrust force, surface roughness andcircularity. S/N ratio is employed to determine the optimum combination of the control fac tor. From the result it isconcluded that TiAlN coated tool lead all other tools for all responses.HSS gives better result than uncoated solidcarbide tool for surface roughness. It is observed that surface roughness and thrust force value improves with increase incutting speed and decrease in feed rate. Furthermore circularity deteriorates with increase in cutting speed and feed rateboth. For thrust force cutting speed is most significant parameter while for surface roughness and circularity tool andfeed rate is significant parameters respectively. The empirical relation between parameters and responses are developedusing multiple regression analysis.
