Creating a G code program
7.4 Fundamentals
There are parameters in the cycle screens whose names depend on this plane setting.
These are usually parameters that refer to positions of the axes, such as reference point of a
position pattern in the plane or depth specification when drilling in the tool axis.
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.

Programming a tool (T)

Calling a tool
220
1.
You are in a part program
2.
Press the "Select tool" softkey.
The "Tool selection" window is opened.
3.
Position the cursor on the desired tool and press the "To program" soft-
key.
The selected tool is loaded into the G code editor. Text such as the fol-
lowing is displayed at the current cursor position in the G code editor:
T="ROUGHINGTOOL100"
- 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".
The selected tool is loaded into the G code editor.
6.
Then program the tool change (M6), the spindle direction (M3/M4), the
spindle speed (S...), the feedrate (F), the feedrate type (G94, G95,...),
the coolant (M7/M8) and, if required, further tool-specific functions.
