Micro drilling operation for Ti6Al4V alloy to investigate the effects of cutting conditions

In this study, the size of burrs occurring in the hole after drilling operations conducted in different conditions of cooling and cutting, hole surface roughness, cutting force and torque 's changes are investigated in detail. For this purpose, especially in the aerospace and biomedical sectors commonly used Ti-6Al-4V material is chosen as the workpiece. The four different cooling methods used in this study, the amount of burr holes occurring in the input and output were determined by 3D profilometer. Also the cooling process influence the surface quality of the hole and the tool damage occurring in the types have been identified. Obtained results; the cooling techniques used in the micro drilling operation, to reduce the burr, showed to have a significant not effect. But to say that the cryogenic cutting burrs less than the amount obtained as a result. The tool wear of the used cooling method would not be wrong to say that significant influence. Flooded, and in particular oil drilling holes with MQL significant change has occurred in the tool diameter. But dry cutting and wear occurring on the team in cryogenic drilling operation has been found to occur as a result of the more abrasive wear mechanism.
