17.1 Graphics
Application
In the program run modes of operation as well as in the Test
Run mode, the TNC graphically simulates the machining of the
workpiece. Using soft keys, select whether you desire:
Plan view
Projection in three planes
3-D view
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, you can
also simulate the machining operation with a spherical cutter. For
this purpose, enter R2 = R in the tool table.
The TNC will not show a graphic if
the current program has no valid workpiece blank definition
no program is selected
The TNC graphic does not show a radius oversize
DR
that has been programmed in the
TOOL CALL block.
A graphic simulation is only possible under certain
conditions for program sections or programs in which
rotary axis movements are defined. The graphic may
not be displayed correctly by the TNC.
The simulation of programs with 5-axis machining or
tilted machining might run at reduced speed. Press
the RESOLUTION soft key in order to reduce the
resolution of the graphics, thereby increasing the
simulation speed. Pressing the RESOLUTION soft
key cycles the graphics resolution through
High ,
Medium and Low.
