Element information
At the bottom left of the screen, the TNC displays information
about the contour element that you last selected via mouse click in
the left or right window.
End point of the straight line, and the starting point is grayed
out.
Circle center point, circle end point, and direction of rotation.
Grayed out: the starting point and circle radius
Select a contour for a turning operation
You can also use the DXF converter to select contours for turning.
Before you enter a milling contour, you must set the datum to the
rotation center. If you select a turning contour, it is saved with Z
and X coordinates. In addition, all X coordinate values in turning
contours are transferred as diameter values, i.e. the drawing
dimensions for the X axis are doubled. All contour elements below
the center of rotation are not selected and are saved in gray.
Select the mode of a turning contour: The TNC
shows only the selectable elements above the
rotation center
Use the left mouse key to select the desired
contour elements: The TNC displays the selected
contour elements in blue and shows the selected
element with a symbol (circular or straight) in the
left window
Selecting and saving machining positions
You must use the touchpad on the TNC keyboard or a
mouse attached via the USB port in order to select a
machining position.
If the positions to be selected are very close to one
another, use the zoom function.
If required, configure the basic settings so that the
TNC shows the tool paths, See "Basic settings",
page 232.
Three possibilities are available in the pattern generator for defining
machining positions:
Individual selection: You select the desired machining position
through individual mouse clicks (See "Single selection",
page 242)
Quick selection of hole positions in an area defined by the
mouse: By dragging the mouse to define an area, you can
select all the hole positions within it ("Rapid selection of hole
positions with the mouse area").
Quick selection of hole positions by entering a diameter: By
entering a hole diameter, you can select all hole positions with
that diameter in the DXF file ("Rapid selection of hole positions
by entering a diameter").
