Note
Thread turns not displayed
For thread and drill thread milling, the thread turns are not displayed in the simulation and for
simultaneous recording.
Display variants
You can choose between three variants of graphical display:
• Simulation before machining of the workpiece
Before machining the workpiece on the machine, you can perform a quick run-through in
order to graphically display how the program will be executed.
• Simultaneous recording before machining of the workpiece
Before machining the workpiece on the machine, you can graphically display how the
program will be executed during the program test and dry run feedrate. The machine axes do
not move if you have selected "no axis motion".
• Simultaneous recording during machining of the workpiece
You can follow machining of the workpiece on the screen while the program is being
executed on the machine.
Views
The following views are available for all three variants:
• Top view
• 3D view
• Side views
Status display
The current axis coordinates, the override, the current tool with cutting edge, the current
program block, the feedrate and the machining time are displayed.
In all views, a clock is displayed during graphical processing. The machining time is displayed in
hours, minutes and seconds. It is approximately equal to the time that the program requires for
processing including the tool change.
Determining the program runtime
The program runtime is determined when executing the simulation. The program runtime is
temporarily displayed in the editor at the end of the program.
