The process of sanding on wood ensures a better surface finish improving the visual aspect, the sensitive and allowing a better use of paints and varnishes. This process is used when the primary machining requirements does not guarantee quality. Thus, further studies are needed involving the sanding process that is widely used in wood industries.In this work, we studied the influence of grain size of abrasives and wear of abrasive grains in plan sanding of Pinus elliottii anda Corymbia citriodora, made parallel to the fibers. Was used in this experiment three different particle size abrasives - P80, P100 and P120 - which material is silicon carbide (SiC) and also three different situations of wear of the abrasive material. The analysis was performed using as parameters power, vibration, the noise emissions measured during the process and the roughness to conclude if the treatments have produced significant effect. The results showed that the grain size of abrasives influence on all output variables and the wear of the grains just not influenced the vibration. The tests were done based on both ANOVA and Tukey's test (a = 0.05)
