Part program in first channel

Code (excerpt)

N100 $P_NCBFR[0] = CTRANS( x, 10 )

N130 $P_NCBFRAME[0] = CROT(X, 45)

Part program in second channel

Code (excerpt)

N100 $P_NCBFR[0] = CTRANS( x, 10 )

N510 G500 X10

N520 $P_CHBFRAME[0] = CTRANS( x, 10 )

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)

Several channel axes can become geometry axes on a transformation change.

Activation of the NC global basic frame

Activation of the NC global basic frame with rotation =>

alarm 18310, since rotations of NC global frames

are not permitted

The NCU global basic frame is also active in second

Activate basic frame

Current frame of second channel is activated with an

; Frame is retained after geo axis substitution.

; 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)
