COORDINATE TRANSFORMATION
·M· & ·EN· MODELS
SOFT: V02.2X
Case –A–
No transformation has been done and the spindle is spinning.
If a Z axis movement is programmed (G01 Z), this axis will move according to the part coordinate
system which, in this case, coincides with machine coordinates.
Now, to move the tool according to the tool coordinate system, function G47 must be used when
programming the movement of the Z axis (G01 G47 Z).
In this type of movements, when the tool coordinate system does not coincide with the machine
coordinate system, the CNC moves several axes in order to move the tool according to the part
coordinates. In the example, the X and Z axes move.
Function G47 is not modal and only affects the programmed movement.
In order for the jog movements, to be carried out according to the tool coordinate system, the CNC
general logic input "TOOLMOVE (M5021" must be activated at the PLC.
