F2: Multi-axis transformations
1.7 Generic 5-axis transformation and variants
Orientation
1. Orientation with axis interpolation
If the 7th axis should have no influence on the programmed orientation, the G codes of
Groups 25 and 51 must be set accordingly:
G code group 25: ORIMKS
G code group 51: ORIAXES (if MD 21104 $MC_ORI_IPO_WITH_G_CODE = 1 is set).
The programmed positions of the rotary axes are not changed by the position of the 7th
axis in this case, but approached directly. The orientation is programmed in relation to the
machine.
Example
Program code
TRAORI(1)
ORIAXES
ORIMKS
G1 X500 Y300 Z800 C15 A5 C1=10 E1=120
1. Orientation and large circle interpolation
If traversing is to be done with large radius circular interpolation, the end orientation is
rotated with the 7th axis.
G code group 25: ORIWKS
G code group 51: ORIVECT (if MD 21104 $MC_ORI_IPO_WITH_G_CODE = 1 is set).
In this case the orientation must be programmed in relation to the workpiece. The
programmed orientation is thus related to the fixed workpiece. The position of the 7th axis
is thus not contained in the programmed orientation.
