Effect of the sand-blasting of edge peeling tools on the cutting forces and wear resistance
TypeCommunications avec actes
One of the major problems concerning tools of wood industry is nicks occurrence on the cutting edge. This phenomenon is accentuated by the small tool angle of most of the wood machining tools. The aim of this present study is to look if the geometry modifications of the cutting edge permit to decrease the weakness of the tools, especially in peeling process. For this, different sand-blasted tools were tested in laboratory peeling of beech. In addition, the adhesion of CrAlN hard coating deposited on a modified cutting edge was also explored. The results obtained showed that the artificial wear by sand-blasting permits to increase the shocks resistance, coatings anchoring and changes the wear mechanism of the tools.
