| Summary: | The high speed milling of silicon carbide was discussed by using flat end-mill 2 mm in
diameter diamond coated tool. Ultra-precision high speed spindle attachment was used to achieve
cutting tool rotation speed as high as 50,000 rpm. Special fixture was designed to minimize the
chatter on work-piece surface during the machining process. Three cutting parameters were selected
as independent variables of the experiments. They were spindle speed, depth of cut and feed rate.
The arithmetic mean value of roughness (Ra) was measured on the work-piece surface as the
response of the experiment. Result of the experiment shows that the value of surface roughness can
be achieved as low as 0.150 μm. Statistical analysis was provided to study the significant of the
model, interaction among the cutting parameters and their effects to the surface roughness value. |
