Check Tic-coated Tungsten Carbide Tool Wear in Machining Steel
In industrial production systems, including the most important factors in the economic field machining operations, reduce tool wear due to abrasive nature of the phenomenon on many factors, including temperature Lathe tool, influences, machining conditions (cutting speed, speed losses, forcing to rebuild parts of the manufacturing tolerances disassemble tool wear is caused by the phenomenon, as...
متن کاملModelling and Numerical Simulation of Cutting Stress in End Milling of Titanium Alloy using Carbide Coated Tool
Based on the cutting force theory, the cutting stress in end milling operation was predicted satisfactorily through simulation of using finite element method. The mechanistic force models were introduced in high accuracy force predictions for most applications. The material properties in the simulations were defined based on the cutting force theory, as a function of strain and strain rate wher...
متن کاملWear and tool life of tungsten carbide, PCBN and PCD cutting tools
The wear mechanisms of cutting tools made of tungsten-carbide (WC), PCBN and PCD were investigated using the tool life and temperature results available in the literature. For tool/work combinations WC/steel and PCBN/hardened-steel, under practical conditions, tool wear was found to be greatly influenced by the temperature. It was concluded that the most likely dominant tool wear mechanism for ...
متن کاملSingle Point Diamond Turning of CVD coated Silicon Carbide
Scratching experiments, using diamond styli and single point diamond tools, were performed to simulate Single Point Diamond Turning (SPDT). The results of these experiments were used to determine if a ductile response is possible, and then to determine the critical depth of cut or penetration depth for the ductile to brittle transition (DBT). The depths of the scratches produced at different lo...
متن کاملControl of eta carbide formation in tungsten carbide powders sputter-coated with (Fe/Ni/Cr)
Composite powders of tungsten carbide with variable coating contents of Fe/Ni/Cr based alloys (1–15 wt.%) were prepared by sputtering. The coated powders have revealed a good performance to shape-forming and sintering. However, the presence of nanocrystalline coatings could enhance the formation of a brittle phase during sintering, named g-phase, (M,W)6C. To investigate this effect, the powders...
