3.11 Orientation vectors
Programming
ORIPLANE
ORICONCW
ORICONCCW
Programming of the direction vector is carried out using the identifiers A6, B6, C6 and is
specified as a (normalized) vector.
Note
Programming of an end orientation is not absolutely necessary. If no end orientation is
specified, a full outside cone with 360 degrees is interpolated.
The opening angle of the taper is programmed with NUT= <angle>, where the angle is specified
in degrees.
Note
An end orientation must be specified. A complete outside cone with 360 degrees cannot be
interpolated in this way. The sign of the opening angle defines whether the traversing angle is
to be greater or less than 180 degrees.
The identifiers have the following meanings:
NUT = +...
NUT = -...
A positive sign can be omitted when programming.
Settings for intermediate orientation
ORICONIO
If this G command is active, it is necessary to specify an intermediate orientation with A7, B7,
C7 which is specified as a (normalized) vector.
Note
Programming of the end orientation is absolutely necessary in this case.
The change in orientation and the direction of rotation is defined uniquely by the three vectors
Start, End and Intermediate orientation.
