Cutting Condition of Chemical-Wood in Lathe Turning
SHIMADA, Kazunori
Abstract
The purpose of this study is to explore the optimum cutting condition of chemical-wood in lathe turning. We conducted an experiment with the following cutting operations; straight turning and end-surface preparation. The results were, 1) From the experiment of straight turning, we found that the cutting speed has a low effect on surface roughness. On the other hand, the feed rate has a noticeable effect on it. We observed that the optimum feed rate is about 0.2mm/rev. 2) From the experiment of end-surface preparation, we grasped that there is no effect of the cutting speed within a range of about 57-226m/min on surface roughness. We also observed that surface roughness is more in accordance with the theoretical roughness value with a feed rate of 0.2 mm/rev than 0.1 mm/rev.
