Smoothing orientation with OSD or OST
When blending with
G642, the maximum variance for the contour axes and orientation axes
cannot vary greatly. The smaller tolerance of the two determines the type of smoothing
motion and/or angular tolerance to smooth the orientation characteristic relatively strongly
without having to accept higher contour deviations.
OSD and OST can be activated to "generously" smooth very slight deviations from the
orientation characteristics with a specified smoothing distance and angular tolerance without
serious contour deviations.
Note
Unlike the process of rounding the contour (and orientation characteristics) with
G642, when
rounding the orientation with
OSD and/or OST, a separate block is not formed, instead the
rounding movement is added directly to the programmed original blocks.
With
OSD and/or OST, block transitions cannot be rounded if there is a change in the type of
interpolation for tool orientation (vector → rotary axis, rotary axis → vector). These block
transitions can if necessary be rounded with the standard rounding functions
G641, G642 and
G643.
