Tungsten Carbide Woodcutting Tool Cutting Forces (2)

For the tungsten carbide woodcutting tool, the inclination of knife in its holder has an impact on the magnitude of the cutting forces applied as well.


The inclining the knife to the work piece advanced in input energy quantity control, which results in a lower transfer of stress from tool face to wood, hence causing smaller deformation zones in the contact zone. Some researchers measured the normal cutting force for a range of cemented carbides when cutting particleboard and found that the edge recession increased with increasing cutting force for the range of materials tested. The cutting forces measured were dependent on the binder content of the hard metal, with higher forces being recorded with increasing binder content.
