Investigations on cutting force, surface quality and
dimension accuracy etc. are ongoing considering the feed rate
and cutting speed despite the development of new drill qualities
in terms of the material and geometry in drilling. In this study,
the drillability of AISI 430 ferritic stainless steel used in many
industrial environments such as automobile chassis parts, hot
water tanks, kitchen utensils and decorative applications was
investigated. The effects on thrust force, torque and surface
quality of cutting speed and feed rate was evaluated in the
drilling of workpiece prepared in sheet form. Experiments were
performed with three different cutting speeds and feed rate with
the uncoated carbide drill bit. Variance analysis was applied to
determine the effect levels of the drilling parameters on the
machining outputs. According to the experimental results, it was
determined that as the feed rate increases, thrust force, torque
and surface roughness increases. On the other hand, it has been
observed that as the cutting speed increases, the machining
outputs tends to decrease.
