Machining planes
A plane is defined by means of two coordinate axes. The third coordinate axis (tool axis) is
perpendicular to this plane and determines the infeed direction of the tool (e.g. for 2½-D
machining).
When programming, it is necessary to specify the working plane so that the control system
can calculate the tool offset values correctly. The plane is also relevant to certain types of
circular programming and polar coordinates.

Working planes
Working planes are defined as follows:

Current planes in cycles and input screens
Each input screen has a selection box for the planes, if the planes have not been specified
by NC machine data.
●
Empty (for compatibility reasons to screen forms without plane)
●
G17 (XY)
●
G18 (ZX)
●
G19 (YZ)
There are parameters in the cycle screens that have names dependent on this plane setting
and that are displayed accordingly, e.g. Z0, Z1 or X0, Y0.
If the entry field remains empty, the parameters, the help screens and the broken-line
graphics are displayed in the default plane (can be set via machine data):
