Setting Button
Contour transfer mode, set the tolerance: 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 depends on the
extent of the entire DXF file
The mode for point transfer on circles and
circle segments determines whether the TNC
automatically loads the circle center point
when selecting machining positions via mouse
click (OFF), or if additional points on the circle
should be shown as well.
OFF
Do not show
additional points on
the circle. Assume the circle center point
directly when a circle or arc is clicked
ON
Show
additional points on the circle.
Assume each desired circle point by clicking
it
Mode for point assumption: Specify whether
the TNC should display the tool path during
selection of machining positions.
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.
