EFFECT OF CUTTING PARAMETERS ON DUST EMISSION AND SURFACE ROUGHNESS DURING HELICAL PLANING RED OAK WOOD

Cutting parameters can influence the chip thickness and resulting dust emission and surface quality during wood machining. The purpose of this study was to evaluate the effect of cutting parameters on the airborne dust emission (0.1-15 μm) and surface roughness produced by helical planing red oak wood. Two cutting depths (0.5 and 1.0 mm) and eight feed speeds (from 6 to 20 m/min) were combined to obtain four average chip thicknesses (from 0.10 to 0.22 mm). The results showed that dust emission decreases as average chip thickness increases. Dust emission also increased for the higher cutting depth but for thinner chips (0.10 mm thick). For thicker chips, dust emitted was similar for the two studied cutting depths. Regression models for estimating dust emission for each particle size fraction as a function of average chip thickness and cutting depth were developed. Furthermore, higher values of average chip thickness produced higher surface roughness. The best helical planing condition was obtained when using 0.5-mm cutting depth, 0.18-mm average chip thickness, and 16 m/min feed speed. This condition was the fastest feed speed allowable to obtain the best surface quality while minimizing dust production.
