You can graphically display the execution of the program on the
screen, in order to easily control the programming result without
moving the machine axes. In this way, you can detect incorrectly
programmed machining steps early on and prevent erroneous
machining of the workpiece.
In addition, you can conveniently track the machining of the workpiece
on the machine via the graphical display, if the view of the working
area is blocked by coolant, for example.
In this graphical display, ShopTurn shows the workpiece, the tools, the
counter spindle and the headstock on the screen in the correct
proportions, i.e. the programmed blank dimensions from the program
head are used for the workpiece and the tools are variously
symbolized according to the tool type and size. For displaying the
counter spindle and headstock, the dimensions are taken from the
"spindle" input screen form (see Sec. "Spindles").
For the graphical display of G-code programs, ShopTurn displays a
pre-defined blank shape, which you can modify as you wish.
If you have programmed turning machining processes in the main
program, ShopTurn displays the corresponding finished-part contour
for them at the start of the graphical display. Thus, you can easily
compare the current contour with the finished-part contour, and also
detect where possible residual material might remain when machining.
You can choose between three variants of graphical display:

Simulation before machining the workpiece
Before machining the workpiece on the machine, you can
graphically display the execution of the program in a quick run-
through. The machine axes do not move.

Parallel drawing before machining the workpiece
Before machining the workpiece on the machine, you can
graphically display the execution of the program with a test run
feedrate. The machine axes do not move. In contrast to the
simulation, you can use the functions for program control, i.e. you
can stop the graphical execution or have it run block-by-block.

Parallel drawing during machining of the workpiece
While the program is being executed on the machine, you can
track the machining of the workpiece on the screen as well.
