Application
In the Program Run, Single Block and Program Run, Full
Sequence operating modes as well as in the Test Run operating
mode, the TNC simulates the machining of the workpiece.
The TNC features the following views:
Plan view
Projection in three planes
3-D view
In the Test Run operating mode, you can also use
the 3-D line graphics.
The TNC graphic depicts the workpiece as if it were being
machined with a cylindrical end mill.
If a tool table is active, the TNC also considers the entries in the
LCUTS, T-ANGLE and R2 columns.
The TNC will not show a graphic if
the current program has no valid workpiece blank definition
no program is selected
if the BLK FORM block was not yet executed during the
workpiece blank definition with the aid of a subprogram
The simulation of programs with 5-axis machining or
tilted machining might run at reduced speed. With
the MOD menu Graphic settings you and decrease
the model quality and in that way increase the
speed of simulation.
