ORICONTO: Interpolation on the peripheral surface of a taper with tangential tran‐
sition
A6= B6= C6=: Programming of a rotary axis of the taper (normalized vector)
NUT=angle: Opening angle of taper in degrees
NUT=+179: Traverse angle less than or equal to 180 degrees
NUT=-181: Traverse angle greater than or equal to 180 degrees
ORICONIO: Interpolation on the peripheral surface of a taper
A7= B7= C7=: Intermediate orientation (programming as normalized vector)
PHI: Angle of rotation of the orientation about the direction axis of the taper
PSI: Opening angle of the taper
Possible polynomials
PO[PHI]=(a2, a3, a4, a5)
PO[PSI]=(b2, b3, b4, b5)
Apart from the different angles, polynomials can also be programmed
up to the
5th degree
Example: Different changes to orientation

N10 G1 X0 Y0 F5000
N20 TRAORI(1) ; Orientation transformation ON

tor.

N40 ORIPLANE ; Select large-circle interpolation.
N50 A3=0 B3=0 C3=1
N60 A3=0 B3=1 C3=1 ; Orientation in the Y/Z plane is rota-
ted through 45 degrees, orientation (0,1/
√2,1/√2) is reached at the end of the
block.
…
N70 ORICONCW ; Orientation programming on the outside
of the taper:
N80 A6=0 B6=0 C6=1 A3=0 B3=0 C3=1 The orientation vector is interpolated
on the outside of a taper with the direc-
tion (0,0,1) up to the orientation (1/
√2,0,1/√2) in the clockwise sense, the
angle of rotation is 270 degrees.
N90 A6=0 B6=0 C6=1 ; The tool orientation goes through a
full revolution on the outside of the
same taper.
Further information
If changes of orientation along the peripheral surface of a taper anywhere in space are to be
described, the vector about which the tool orientation is to be rotated must be known. The start
and end orientation must also be specified. The start orientation results from the previous block
and the end orientation has to be programmed or defined via other conditions.
