Contour element 1
The contour starts with a chamfer (thread chamfer).
The starting point of the contour is defined in "XS, ZS"
when programming the first contour element. The
starting point, in this case, is the corner that is cut off
by the chamfer.
If you program a chamfer as the first contour element,
you must specify the position of the chamfer with the
parameter "element position J"—here: "J=1" (see
figure to the upper right).
The control does not know yet the next connecting
contour element. The chamfer is therefore regarded
as an "unsolved element." MANUALplus displays the
appropriate symbol below the graphics window (see
figure to the bottom right).
