Programming a orientation change:
A change in tool orientation can be programmed by:
● Direct programming of rotary axes A, B, C (rotary axis interpolation)
● Euler or RPY angle
● Direction vector (vector interpolation by specifying A3 or B3 or C3)
● LEAD/TILT (face milling)
The reference coordinate system is either the machine coordinate system (ORIMKS) or the
current workpiece coordinate system (ORIWKS).

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 interpo‐
lation 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.
