Minimizing dust emission during routing operation of rubberwood
ABSTRACT The study evaluated airborne dust emission (0.1–10µm) during the routing operation
of Rubberwood (Hevea brasiliensis) in the furniture industry in South
East Asia. It was found that the average chip thickness of 0.1mm and wood moisture content of 12–14%
minimized dust emission, while the cutting tool rake angle had little influence on dust emission. The study
shows that adverse economic implications due to health hazards posed by airborne dust emissions during wood
machining can be reduced by manipulating the average chip thickness and work-piece moisture content.
