Abstract
The objective of this study is to investigate proper cutting conditions of cellulose acetate(CA) for eyewear frames. Various cutting experiments with variation of spindle speeds and feed rates are conducted to evaluate the machinability of CA. The machinability of CA materials were discussed in terms of the cutting forces, surface roughnesses and chip formations. The cutting conditions of high spindle speeds and the feed per tooth of less than 0.05mm are recommended considering the surface roughnesses and chip formations. Also, the correlation between the surface roughness and the chip formation is investigated. These results are able to be applied to design the high-speed machine tool of CA frame.
