Machinability of UMCo50 Cobalt Superalloy

Original language description

Testing of machinability of the UMCo50 superalloy was carried out within the project fol-lowing the actual production of the semi-finished product by casting. Turning was chosen asthe machining method to minimize the effect of an interrupted cut. Considering the machin-ability of a hard-to-machine alloy, the cutting material with the fine-grained WC-Co carbidewith the TiN/TiAlN gradient PVD coating was selected. The progression of cutting forces,chip formation and tool wear were evaluated. Images of the material structure of the semi-finished product and the resulting chips were taken. From the measured values, graphs of thedependence of the chip thickness ratio on the cutting speed and the Taylor ́s dependence ofthe tool durability on the cutting speed were obtained. The aim of the experiment was selec-tion and verification of suitable cutting conditions for efficient machining of this superalloy,especially the appropriate value of the cutting speed. The recommended value of the cuttingspeed was 50-70 m.min-1, while the tangential component of the cutting force was in thevalues usual for corrosion-resistant steels.
