9 Coordinate Systems, Plane Selection

The local coordinate system will be offset in each work coordinate system.

Fig. 9.3-2

Programming instruction G92 will delete the offsets produced by instruction G52 on the axes specified inG92 - as if command G52 v0 had been issued.

Whenever the tool is at point of X=200, Y=120 coordinates in the X, Y work coordinate

system, instruction

G52 X60 Y40

will shift its position to X'=140, Y'=80 in the X', Y' local coordinate system.

Now instruction

G92 X110 Y40

will establish the tool position to X"=110, Y"=40 in the new X", Y" work coordinate system. Thus the X', Y' local coordinate system

will be deleted by command G92 as ifFig. 9.3-3command G52 X0 Y0 had been issued.

LNote:

–The offset of the local coordinate system will be deleted by execution of commands M2, M30 and/or by resetting the program.

9.4 Plane Selection (G17, G18, G19)
The plane in which
– circular interpolation,
– specification of polar coordinate data,
– rotation of coordinate system,
–cutter radius compensation,
– positioning of drilling cycles
will be performed can be selected with the following G
codes:
G17............XpYp plane
G18............ZpXp plane
G19............YpZp plane,
