The TNC also transfers two workpiece-blank
definitions (
BLK FORM
) to the contour program. The
first definition contains the dimensions of the entire
DFX file. The second one, which is the active one,
contains only the selected contour elements, so that
an optimized size of the workpiece blank results.
The TNC only saves elements that have actually
been selected (blue elements), which means that
they have been given a check mark in the List View
window.
Dividing, extending and shortening contour elements
Proceed as follows to modify contour elements:
The Graphics window is active for the contour
selection
To select the starting point: Select an element or
the intersection between two elements (using the
shift key). A red star is displayed as the starting
point.
To select the next contour element: Click the
desired element with the mouse. The TNC
displays the machining sequence as a dashed
straight line. When the element is selected the
TNC displays it in blue. If the elements cannot be
connected the TNC displays the selected element
in gray.
If further contour elements in the selected
machining sequence are selectable, the TNC
highlights these elements in green. With
divergences, the element with the lowest angle
distance is selected. Click on the last green
element to assume all elements into the contour
program
You select the machining sequence of the contour
with the first contour element.
If the contour element to be extended or shortened
is a straight line, then the TNC extends/shortens the
contour element along the same line. If the contour
element to be extended or shortened is a circular arc,
then the TNC extends/shortens the contour element
along the same arc.
