碩士 === 南台科技大學 === 機械工程系 === 102 === This study tries to explore the effect of cutting conditions on the surface quality of wood, it mainly focuses on the effect of cutting time, different radial cutting width and cutting path on the surface roughness of wood samples after cutting operation. Generally speaking, the smaller the radial cutting width the better the surface quality of wood.On the other hand, the high speed coupled with low feed rate would also get better surface quality. Therefore, when we fix the tool diameter, spindle speed and feed rate, and change the operation parameters such as cutting path ( reciprocating cutting path, unidirectional cutting path and scroll cutting path ) and radial cutting width ( 0.1 mm, 0.3 mm and 0.5 mm ), we explore the effect of cutting conditions on the surface quality of wood.In order to measure the average surface roughness after cutting operation. It is measured in accordance with the parallel and perpendicular direction of wood grain, and with six replications measurement to get average value. The results show that the best quality of cutting surface is by scroll cutting path with 0.1 mm cutting width. The cutting time is 166 seconds.
