Specification Of Orientation For Two Contact Points (Oricurve, Po[Xh]=, Po[Yh]=, Po[Zh]=) - Siemens SINUMERIK 840D sl Programming Manual

Programming in the ORIPLANE plane corresponds to ORIVECT
The programming of large-radius circular interpolation together with angle polynomials
corresponds to the linear and polynomial interpolation of contours. The tool orientation is
interpolated in a plane that is defined by the start and end orientation. If additional polynomials
are programmed, the orientation vector can also be tilted out of the plane.
Programming of circles in a plane G2/G3, CIP and CT
The extended orientation corresponds to the interpolation of circles in a plane. For information
about the programming options for circles with centerpoint data or radius data, such as G2/G3,
circle via intermediate point CIP and tangential circles CT see Chapter "Circular interpolation
(Page 188)".
Orientation programming
Interpolation of the orientation vector on the peripheral surface of a taper ORICONxx
Four different types of interpolation from G group 51 can be selected for interpolating
orientations on the peripheral surface of a taper:
1. Interpolation on the outside of a taper in the clockwise direction ORICONCW with
specification of end orientation and taper direction, or opening angle. The direction vector
is programmed with identifiers A6, B6, C6 and the opening angle of the taper with identifier
NUT= value range in interval 0 degrees to 180 degrees.
2. Interpolation on the outside of a taper in the counter-clockwise direction ORICONCCW with
specification of end orientation and taper direction, or opening angle. The direction vector
is programmed with identifiers A6, B6, C6 and the opening angle of the taper with identifier
NUT= value range in interval 0 degrees to 180 degrees.
3. Interpolation on the outside of a taper ORICONIO with specification of end orientation and
an intermediate orientation, which is programmed with identifiers A7, B7, C7.
4. Interpolation on the outside of a taper ORICONTO with tangential transition and
specification of end orientation. The direction vector is programmed with identifiers A6, B6,
C6.

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.
