Note
All commands for smoothing the tool orientation (OSOF, OSC, OSS, OSSE, OSD, and OST) are

7.6 Tool orientation (ORIC, ORID, OSOF, OSC, OSS, OSSE, ORIS, OSD, OST)
Significance
Orientation and path movement in parallel
Orientation and path movement consecutively
No orientation smoothing
Orientation constantly
Orientation smoothing only at beginning of block
Orientation smoothing at beginning and end of block
Velocity of the orientation change with orientation smoothing activated in
degrees per mm (valid for OSS and OSSE)
Smoothing of orientation by specifying smoothing distance with setting data:
SD42674 $SC_ORI_SMOOTH_DIST
Smoothing of orientation by specifying angular tolerance in degrees for
vector interpolation with setting data:
SD42676 $SC_ORI_SMOOTH_TOL
With rotary axis interpolation, the specified tolerance is assumed to be the
maximum variance of the orientation axes.
