Function
In automatic mode you can display your program graphically in the
"Program test" function before machining, without traversing the
machine axes.
The simulation graphic shows a representation of a workpiece being
machined by a cylindrical tool. You can select different views via
softkey, e.g.
• Top view
• Representation in three planes
• 3D representation (volume model)
The status displays in the simulation graphic contain information
• about the actual axis coordinates and
• the block currently being processed.
This function is an option and is only available with a color display.
Milling simulation is only possible in the 1st channel.
Operating sequence
• You select the program in automatic mode "Auto".
• In the Machine operating area under "Program control," the
functions "Dry run feedrate" and "Program testing" (the machine is
not moved while the program is run) are selected. If the "Dry run
feedrate" function is active, the programmed feedrate is replaced
by a defined dry run feedrate.
• Tool T0:
• Tool not identical with T0:
Select a program of your choice and open it.
Press the "3D sim" softkey.
The program is started.
You can follow program execution on the screen.
