In this study effect of cutting parameters on thrust force, surface roughness and circularity are investigated during 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 TiAlNcoated solid 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 and circularity. S/N ratio is employed to determine the optimum combination of the control factor. From the result it is concluded that TiAlN coated tool lead all other tools for all responses.HSS gives better result than uncoated solid carbide tool for surface roughness. It is observed that surface roughness and thrust force value improves with increase in cutting speed and decrease in feed rate. Furthermore circularity deteriorates with increase in cutting speed and feed rate both. For thrust force cutting speed is most significant parameter while for surface roughness and circularity tool and feed rate is significant parameters respectively. The empirical relation between parameters and responses are developed using multiple regression analysis.
