ORICONTO Interpolation on a peripheral surface of the cone with tangential
transition
Also required:
A3=... B3=... C3=... or XH=..., YH=..., ZH=... End orientation
With POLY, PO[PHI] = ..., PO[PSI]=... can also be programmed in
these cases. This is a more generalized form of large circle
interpolation, whereby polynomials are programmed for the lead and
tilt angles. With cone interpolation, the polynomials have the same
significance as with large circle interpolation for the given start and end
orientations. The polynomials can be programmed with ORIVECT,
ORIPLANE, ORICONCW, ORICONCCW, ORICONIO, ORICONTO.
ORICURVE Orientation interpolation with specification of the tool tip motion and
that of a second point on the tool.
The path of the second point is defined via XH=... YH=... ZH=..., in
conjunction with BSPLINE as a control polygon with POLY as
polynomial:'
PO[XH] = (xe, x2, x3, x4, x5) PO[YH] = (ye, y2, y3, y4, y5)
PO[ZH] = (ze, z2, z3, z4, z5)
If the BSPLINE or POLY additional information is omitted,
straightforward linear interpolation will be performed accordingly
between the start and the end orientation.
ORISON Smoothing of the orientation characteristic ON. The "Smoothing the
orientation characteristic (ORISON)" function can be used to smooth
oscillations affecting orientation over several blocks. The aim is to
achieve a smooth characteristic for both the orientation and the
contour.
ORISOF Smoothing of the orientation characteristic OFF.
