ABSTRACT: Surface
roughness is one of the most important evaluation indexes in machine cutting.
In order to analyze how the tool path affects the roughness of the surface
after milling, series of simulations are implemented in MasterCAM. We set up
the same processing conditions with same parameters such as speed, material and
feed rate etc. in these simulations, but different processing paths are used. We
choose three paths: the parallel milling along the X-Y axis direction, the
parallel milling along the Z-X or Z-Y axis direction and the streamline
processing in the simulations. At the same time, end miller, arc miller and
ball miller are respectively selected in the software. So there are totally 9
simulations of the milling process that are performed. Then the experimental
cutting processes are performed correspondingly and the surface roughness and the
accuracy are measured. The results show that the milling effect of the arc is
better and the waste is minimal in the parallel milling along the Z-X or Z-Y
axis direction with the end mills.
