7.3 Orientation polynomials (PO[angle], PO[coordinate])
Parameters
PO[PHI]
PO[PSI]
PO[THT]
PHI
PSI
THETA
PO[XH]
PO[YH]
PO[ZH]
Description
Orientation polynomials cannot be programmed:
• If ASPLINE, BSPLINE, CSPLINE spline interpolations are active.
• If the orientation is interpolated using ORIAXES axis interpolation. In this case,
Type 1 orientation polynomials with ORIVECT, ORIPLANE and ORICONxx
Only type 1 orientation polynomials are possible for large-radius circular interpolation and
interpolation outside of the taper with ORIVECT, ORIPLANE and ORICONxx.
Type 2 orientation polynomials with ORICURVE
If interpolation with the additional curve in space ORICURVE is active, the Cartesian
components of the orientation vector are interpolated and only type 2 orientation polynomials
are possible.
7-34
Type 1 polynomials for orientation angles are possible for every type of interpolation
except spline interpolation, that is, linear interpolation with rapid traverse G00 or with
feedrate G01
with polynomial interpolation using POLY and
circular/involute interpolation G02, G03, CIP, CT, INVCW and INCCCW.
However, type 2 polynomials for orientation coordinates are only possible if
linear interpolation with rapid traverse G00 or with feedrate G01 or
polynomial interpolation with POLY is active.
polynomials can be programmed directly with PO[A] and PO[B] for orientation
axes A and B.
Angle in the plane between start and end orientation
Angle describing the tilt of the orientation from the
plane between start and end orientation
Angle of rotation created by rotating the rotation
vector of one of the G codes of group 54 that is
programmed using THETA
Lead angle LEAD
Tilt angle TILT
Rotation about the tool direction in Z
X coordinate of the reference point on the tool
Y coordinate of the reference point on the tool
Z coordinate of the reference point on the tool
