Programming A Tool (T) - Siemens SINUMERIK 840D sl Turning Operating Manual

For G17, reference points in the plane are called X0 Y0, for G18 they are called Z0 X0 - and for
G19, they are called Y0 Z0. The depth specification in the tool axis for G17 is called Z1, for G18,
Y1 and for G19, X1.
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):
● Turning: G18 (ZX)
● Milling: G17 (XY)
The plane is transferred to the cycles as new parameter. The plane is output in the cycle, i.e.
the cycle runs in the entered plane. It is also possible to leave the plane fields empty and thus
create a plane-independent program.
The entered plane only applies for this cycle (not modal)! At the end of the cycle, the plane from
the main program applies again. In this way, a new cycle can be inserted in a program without
having to change the plane for the remaining program.

- OR -
4. Press the "Tool list" and "New tool" softkeys.
5. Then select the required tool using the softkeys on the vertical softkey
bar, parameterize it and then press the softkey "To program".
