Contour description for protection zone
The contour of a protection zone is described with traversing motions. These are not executed and have no
connection to previous or subsequent geometry descriptions. They only define the protection zone.
The contour of a protection zones is specified with up to eleven traversing movements in the selected working
plane. The first traversing movement is the movement to the contour. The last point in the contour description
must always coincide with the first point of the contour description. In the case of rotationsymmetrical contours
(e.g. spindle chuck), the whole contour must be described (not merely the contour to the turning center).
The valid protection zone is the zone left of the contour:
• Internal protection zone
The contour of an internal protection zone must described in the counterclockwise direction.
• External protection zones (permitted only for workpiece-related protection zones)
The contour of an external protection zone must be described in the clockwise direction.
Figure 2-11 Examples: External and internal protection zone
Toolrelated protection zones must be convex. If a concave protection zone is required, the protection zone must
be divided up into several convex protection zones.
