This functions for approaching and leaving a contour
are effective blockwise.
In the approaching block have to be determined:
the coordinates of the start point P0 of the contour
the value B (approaching distance without contour
touch)
In the leaving block must be determined:
the coordinates of the start point PE after leaving
the contour
the value B (leaving distance without contour touch)
In an approaching or leaving block no further
traverse movements must be programmed.
After an approaching or leaving block no block
must be programmed which contains only auxiliary
functions.
G41 or G42 must be active before an approaching
block.
In the leaving block G40 will be set automatically,
that means, G41 or G42 have to be programmed
again.
Soft approaching or leaving is not possible with
contours which were programmed with contour
drafts.
PA Start point before approaching the contour
PS Supporting point, will be calculated by the control
basing on B
