Frames

Example 1
The channel axis is to become a geometry axis through geometry axis substitution.
The substitution is to give the programmable frame a translation component of 10 in the X axis.
The current settable frame is to be retained:
FRAME_GEOX_CHANGE_MODE = 1
$P_UIFR[1] = CROT(x,10,y,20,z,30) ; Frame is retained after geo axis substitution.

TRANS a10
GEOAX(1, a)
Several channel axes can become geometry axes on a transformation change.
Example 2
Channel axes 4, 5 and 6 become the geometry axes of a 5axis orientation transformation. The
geometry axes are thus all substituted before the transformation.
The current frames are changed when the transformation is activated.
The axial frame components of the channel axes, which become geometry axes, are taken
into account when calculating the new WCS. Rotations programmed before the transformation
are retained. The old WCS is restored when the transformation is deactivated.
The most common application will be that the geometry axes do not change before and after
the transformation and that the frames are to stay as they were before the transformation.
Machine data:
$MN_FRAME_GEOAX_CHANGE_MODE = 1
$MC_AXCONF_CHANAX_NAME_TAB[0] = "CAX"

Comment
; The NCU global basic frame is also active in second chan-
nel.
; Activate basic frame
; Current frame of second channel is activated with an off-
set.
; Settable frame becomes active.
; Axial offset of a is also substituted.
; a becomes x axis.
; $P_ACTFRAME= CROT(x,10,y,20,z,30):CTRANS(x10)
