Smoothing orientation with OSD or OST
When blending with
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
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
rounding the orientation with
rounding movement is added directly to the programmed original blocks.
With
interpolation for tool orientation (vector → rotary axis, rotary axis → vector). These block
transitions can if necessary be rounded with the standard rounding functions
