Orientation programming
Interpolation of the orientation vector on the peripheral surface of a taper ORICONxx
Four different types of interpolation from G-code 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 counterclockwise 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.
7.2.9 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. It is also possible
to activate a spline interpolation with BSPLINE. Other types of splines (ASPLINE and
CSPLINE) and the activation of a compressor using COMPON, COMPCURV or COMPCAD
are not permissible.
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.
