Test Condition:
• Work Piece: Aluminum block
• Tool: Carbide end mill with 8 mm diameter
• Roatating speed: 1400rpm
• Feeding speed: 100mm/min
• Milling depth: 5 mm
• Process: Continuous milling without repointing
• CTQ: Top flute wear
After Test:
After 2 hours of milling with uncoated Carbide End Mill
With Uncoated End Mill
Surface Morphology of Al Block
Severe wear is observed
Texture line on surface is damaged
Surface becomes rough
After 4 hours of milling with ta-C coated Carbide End Mill
With ta-C coated End Mill
Surface Morphology of Al Block
Minimum wear
Texture line on surface remains intact
Surface is still smooth
Conclusion :
ta-C coating helps to prolong lifespan of end mills significantly and improve finished milling surface.
ta-C coated cutters are capable of performing dry cutting operations.
