In this study, tool direction was a significant factor when machining the end and flat grain surfaces.
Further analysis found significant differences due to tool wear for the conventionally machined end grain and climb cut flat grain surfaces (Table 3) for samples machined at 18,000 rpm.
In climb cutting flat grain surfaces, increasing the feed per knife had no significant impact on quality (Table 4 and Fig.
On flat grain surfaces, climb cutting produced a higher quality surface compared to conventional cutting.
Quality machining of flat grain surfaces can be accomplished with ease, as evidenced by the lack of differences in surface quality with increasing feed per knife on flat grain surfaces with either sharp or dull knives.
This dweller of the small intestine regularly sheds segments, which look like little, mobile, flat grains
of rice, each of which contains about 20 eggs.
