Orientation types relative to the path

Function
By using this expanded function, relative orientation is not only achieved at the end of the
block, but across the entire trajectory. The orientation achieved in the previous block is
transferred to the programmed end orientation using large-circle interpolation. There are
basically two ways of programming the desired orientation relative to the path:
1. Like the tool rotation, the tool orientation is interpolated relative to the path using
2. The orientation vector is programmed and interpolated in the usual manner. The rotation
Syntax
The type of interpolation of the orientation and the rotation of the tool is programmed using:
N... ORIPATH
N... ORIPATHS
N... ORIROTC
