Starting point of contour elements
(3) = abscissa, (4) = ordinate of the current plane
Starting point of the contour elements
(5) = abscissa, (6) = ordinate of the current plane
Max/min indicator: Identifies local maximum and minimum values on the contour
Maximum value between contour element and abscissa (for longitudinal
machining) or ordinate (for face cutting). The angle depends on the type of
machining programmed.
(9) = abscissa, (10) = ordinate
