Abstract
The proper parameters of sanding with abrasive sanding machine are significant to reduce energy consumption and to improve processing efficiency and quality. The parameters sanding speed, feed speed, and granularity have been investigated in terms of the sanding force (sF) and normal force (nF) for particle board (PB) and medium-density fiberboard (MDF). For PB, the sF and nF show decreasing trends of second power with increasing sanding speed and linear increase when feed speed increases. The sF and nF are almost constant when granularity increases from 40 to 80, but these forces show increasing trends of second power when granularity increases from 80 to 150. For MDF, the sF and nF change as trends of second power with increasing sanding speed and increase in trends of second power with increasing feed speed. The sF and nF force decrease when granularity increases from 40 to 80, but these forces present linear increasing trends when granularity increases from 80 to 150.
