Specification Of Orientation For Two Contact Points (Oricurve, Po[Xh]=, Po[Yh]=, Po[Zh]=) - Siemens SINUMERIK 828D Programming Manual

Transformations
6.2 Three, four and five axis transformation (TRAORI)
6.2.9 Specification of orientation for two contact points (ORICURVE, PO[XH]=,
PO[YH]=, PO[ZH]=)
Function
Programming the change in orientation using the second curve in space ORICURVE
Another way to program changes in orientation, besides using the tool tip along a curve in
space, is to program the motion of a second contact point of the tool using
way, changes in tool orientation can be defined uniquely, as when programming the tool
vector itself.
Machine manufacturer
Please refer to the machine manufacturer's notes on axis identifiers that can be set via
machine data for programming the second orientation path of the tool.
Programming
This type of interpolation can be used to program points (using
POLY
interpolation and the "Combine short spline blocks" function can also be activated.

The motion of the two contact points of the tool can be predefined up to the 5th degree when
programming the orientation polynomials for coordinates.
