Basic settings
The third soft-key row has various possibilities for settings:
Setting Soft key
Show/hide rulers: The TNC shows the rulers at
the left and top edges of the drawing. The values
shown on the ruler are based on the drawing
datum.
Show/hide status bar: The TNC shows the status
bar at the bottom edge of the drawing. The
following information is shown in the status bar:
„ Active unit of measurement (MM or INCH)
„ X and Y coordinates of the current mouse
position
„ In the SELECT CONTOUR mode, the TNC
shows whether the selected contour is open
(open contour)
or closed (closed contour).
Unit of measure MM/INCH: Enter the unit of
measurement of the DXF file. The TNC then
outputs the contour program in this unit of
measurement.
Set 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.
Set resolution: The resolution specifies how
many decimal places the TNC should use when
generating the contour program. Default setting:
4 decimal places (equivalent to resolution of
0.1 µm when the unit of measure MM is active)
Mode for point assumption with circles and arcs:
The mode determines whether the TNC
automatically assumes 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
Do show additional points on the circle.
Assume each desired point by clicking it.
