Özet

In this study, the effects of different cutting conditions on the cutting performance were investigated in the micro milling of Inconel 718. In this context, dry cutting, minimum quantity lubrication and cryogenic pre-cooling were considered as the cutting conditions. Tool wear, surface roughness and burr formation were determined as performance criteria in the cutting processes carried out using an AlCrN-coated tool. At the end of the study, cryogenic pre-cooling led to increased tool wear. In contrast, a significant reduction in surface roughness as well as burr formation was observed in the cutting process with cryogenic pre-cooling. However, the minimum quantity lubrication process increased tool life, but it was not seen as the clear effect for decreasing surface roughness and burr formation.
