Adhesion of dust particles to cutting edges while wood processing I. Identification of adhesion

Some dust particles produced by the cutting of wood and wood-based material s adhere to the surfaces of the cutting edges. The reason for adhesion, the characteristics of the adhered particles, and the effects of them on the m achining conditions or on the manufactured surfaces have not been a theme o f research. For this report, we examined to reveal the particle distributio n attached on the router bit and the relationship of particle size on the a dhesive power. The following results became clear after the examination: 1. The size of the major part of the dust particles produced by the routing of plywood and particleboard was small compared with those of wood materia l. 2. The force of adhesion increases in power when the size of a particles be come small. Experimental results on aodamo (Fraxinus Sp.) particles showed that the adhesion power of 250-mesh particles is greater than that of 200-m esh particles.
