Explanation
Nano smoothing for 5-axis machining
Three basic axes (and their parallel axes) and two rotary axes are interpolated
independently in Nano smoothing for 5-axis machining.
Correct insertion point
At the interpolation for Nano smoothing for 5-axis machining, insertion points
are generated firstly, then the insertion points are corrected, and smooth curve is
generated with the corrected insertion points. This method is same as that of the
conventional Nano smoothing. In three basic axes (or their parallel axes)
interpolation, an insertion points are corrected so that the difference (compound
difference of three axes) between the insertion points and the corrected insertion
points are less than the tolerance which is set in parameter.
In two rotary axes interpolation, an insertion point is corrected so that the both
differences (elements for each axis) between the insertion point and the corrected
insertion point are less than each tolerance which is set in parameter for each
axis.
