Contour selection from an imported DXF fi le Part program on the basis of the imported DXF fi le
You can defi ne the following locations as
reference point:
• The beginning, end or mid-point of a line
• The beginning, end or mid-point of a
circular arc
• Quadrant transitions or center point of a
circle
• Intersection of two lines, regardless of
whether it is located inside or outside
the programmed segments
• Intersection of a line and a circular arc
• Intersection of a line and a circle
If multiple intersections result between
two elements (e.g., between a straight line
and a circle), you can select the correct
intersection with a mouse click.
Contour selection is exceptionally user
friendly. You select any element by clicking
it with the mouse. As soon as you select a
second element, the TNC detects your
desired direction of machining, and starts
the automatic contour detection. The
TNC automatically selects all clearly
identifi able contour elements until the
contour closes or branches out. There you
click the immediately following contour
element. In this way you can defi ne even
extensive contours with just a few mouse
clicks. If desired you can also shorten,
lengthen or interrupt the contour elements.
But you can also select machining
positions and save them as point fi les,
particularly in order to use drilling positions
or starting points for pocket machining.
This can be done very easily: Using the
mouse, simply select the desired area. In a
pop-up window with fi lter function, the
TNC displays all hole diameters that are
within the area you have selected. To select
the desired hole diameters and restrict the
number of hole positions, simply click the
corresponding fi lter symbol to change the
fi lter limits.
A zoom function and various possibilities
for settings round out the functionality of
the DXF converter. Moreover, you can
defi ne the resolution of the contour
program to be uploaded in case you want
to use it on older TNC controls, or a
transition tolerance if occasionally the
elements do not quite adjoin.
