Generating a G code program

8.4 Fundamentals

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

You are in the part program.

Press the "Select tool" softkey.

The "Tool selection" window is opened.

Position the cursor on the desired tool and press the "To program" softkey.

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"

Press the "Tool list" and "New tool" softkeys.

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.

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.
