T. Morita et al., EFFECTS OF WORK MATERIALS ON CUTTING PERFORMANCE OF DIAMOND-COATED CEMENTED CARBIDE TOOLS, Forest products journal, 48(5), 1998, pp. 43-50
Diamond-coated cemented carbide tools, a new type of woodcutting tool,
were made by the hot-filament chemical vapor deposition method. Conti
nuous milling tests with coated and uncoated tools were carried out on
five kinds of work materials: particleboard, medium-density fiberboar
d, plywood, and air-dried and wet melapi (Shorea spp.). Tool-edge appe
arance, edge recession, cutting-surface roughness, and cutting-power c
onsumption are discussed. The results showed that for all of the work
materials, the coated tools were superior to the uncoated tools in red
ucing edge recession, and differences in surface roughness produced by
the coated and uncoated tools were not significant. Power cutting con
sumption for the coated tools, however, was higher than for the uncoat
ed in cutting MDF and in surface milling particleboard. With further s
tudy and improvements in the coating method, diamond-coated tools coul
d find application in the cutting of various wood and wood-based mater
ials.
