With cone surface interpolation, during reori-
entation the tool moves on a programmable
peripheral surface of a cone located anywhere
in space.

Vector interpolation
Interpolation on a peripheral surface of a cone in the clockwise
direction
Interpolation on a peripheral surface of a cone in the counterclock-
wise direction.
Also required in both cases:
A3=... B3=... C3=... or XH=..., YH=..., ZH=... end orientation
Cone's axis of rotation: A6, B6, C6 Opening angle: NUT=...
Interpolation on a peripheral surface of a cone with an intermedi-
ate orientation specified via A7=... B7=..., C7=....
Also required:
A3=... B3=... C3=... or XH=..., YH=..., ZH=... end orientation
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
interpolation, whereby polynomials are programmed for the lead
and tilt angles.
With cone interpolation, the polynomials have the same signifi-
cance as with large circle interpolation for the given start and end
orientations. The polynomials can be programmed with
ORIVECT, ORIPLANE, ORICONCW, ORICONCCW, ORICONIO,
ORICONTO.
