Sažetak
This paper investigates the possibility of finishing miiling of titanium alloy TiAl6V4 compressor gas turbine blades with polycrystalline cubic diamond PCD cutter that can be used successfully for milling slim, low stiffness, blades. The tool life of PCD cutter was very long, 381 minutes while surface roughness of the machined surface was low and the geometrical accuracy was satisfactory. A suitable inclination of the cutter axis to the surface has been determined. A basic consideration of milling titanium based alloy with PCD cutter and an analysis and discussion of the chip formation are presented. Better results are obtained when cooling refrigerant was applied. Finishing miiling of titanium alloy TiAl6V4 slim blades with PCD cutter is promising.
