A change in tool orientation can be programmed by:

• Direct programming of round axes A, B, C (round 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).

8.6 Tool orientation (ORIC, ORID, OSOF, OSC, OSS, OSSE, OSD, OST)

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

Speed of the orientation change for activated

orientation smoothing in degrees per mm; applies to OSS

Rounding of orientation by specifying rounding length

with SD $SC_ORI_SMOOTH_DIST.

Rounding of orientation by specifying angle tolerance

in degrees for vector interpolation with

SD $SC_ORI_SMOOTH_TOL. With round axis interpolation,

the specified tolerance is assumed to be the maximum

variance of the orientation axes.
