A comparison of tool materials, coatings, and treatments related to tool wear during wood machining

The machining of dry wood and reconstituted wood products such as medium-density fiberboard (MDF) involves high temperatures and pressures in the cutting edge zone. Turning tests on MDF with selected tool materials, coatings, and treatments were undertaken to determine their effect on tool wear during wood machining. The results show that tool wear can be reduced by selecting tool materials, coatings, or treatments that are relatively inert at high temperatures and/or can conduct heat away from the cutting zone.
