Tungsten Carbide Woodcutting Tool Cutting Edge Profiles (1)

During the wood machining, as the energy is passed from the tungsten carbide woodcutting tool edge to the wood, so the cutting tool performance could be generally evaluated by the cutting edge profile.



Although the sharper the edge is, the more efficient in focusing the energy will be, it indicates a fast edge deterioration as the same time.Typical cutting edge wear, when cutting wood, is progressive tool nose rounding, which is different from that found when metals are machined in which crater and flank wear often predominate. This typical wear profile consists of a rounded edge joining the rake and clearance faces such that negative rake and clearance angles are produced. The profile has been found to be independent of the tool used or the wood being cut.
