Tungsten carbide tipped tools were introduced to
the woodworking industry in the early 1950s.
Circular saw blades, milling cutters and routers
account for the main share of carbide usage in this
industry. Figures 1-3 show some typical tools for
wood working. The cutting speed in industrial
wood machining ranges from 30 to 100 m s-J,
the feed being 1-2 mm tooth -~. The cutting
forces are comparatively low, but due to the
inhomogeneous structure of natural wood, the tools are subjected to high impact forces during
the intermittent machining of the wood. Tough-
ness is of utmost priority, not only due to the
impact forces but also due to the high centrifugal
forces during the high speed machining. Man
made woods, such as chipboard, contain a large amount of inorganic matter.
