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
ORICURVE. In this
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 G1) or polynomials (using
POLY) for the two curves in space. Circles and involutes are not permitted. A BSPLINE spline
interpolation and the "Combine short spline blocks" function can also be activated.

(B1), chapter: Combine short spline blocks
The other spline types,
ASPLINE and CSPLINE, and compressor activation using COMPON,
COMPCURV or COMPCAD are not permitted.
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.
