The following icons are displayed by the TNC only in certain modes.
Icon Setting
Contour assumption mode:
The tolerance specifies how far apart
neighboring contour elements may be from
each other. You can use the tolerance to
compensate for inaccuracies that occurred
when the drawing was made. The default
setting is 0.0001 mm
Point assumption mode:
Specify whether the TNC should display the
tool path as a dashed straight line during
selection of machining positions
Path optimization mode:
The TNC optimizes the tool traverse movement
to give the shortest traverse movements
between the machining positions. Optimization
is reset with repeated actuations
Please note that you must set the correct unit of
measure, since the DXF file does not contain any
such information.
If you want to generate programs for older TNC
controls, you must limit the resolution to three
decimal places. In addition, you must remove the
comments that the DXF converter inserts into the
contour program.
The TNC displays the active basic settings in the
footer of the screen.
