ORICONTO Interpolation on a peripheral surface of a 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 interpola-
tion, 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 polyno-
mial:'
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, straightfor-
ward linear interpolation will be performed accordingly between the
start and the end orientation.
