2.2 Protection zones
2.2.1 General
Function
Protection zones are static or moveable in 2- or 3-dimensional ranges within a machine to
protect machine elements against collisions.
The following elements can be protected:
Permanent parts of the machine and attachments (e.g. toolholding magazine, swiveling
probe). Only the elements that can be reached by possible axis constellations are
relevant.
Moving parts belonging to the tool (e.g. tool, toolholder)
Moving parts belonging to the workpiece (e.g. parts of the workpiece, clamping table,
clamping shoe, spindle chuck, tailstock).
Protection zones are defined via part program instructions or system variables so that they
completely surround the element to be protected. The activation and deactivation of
protection zones also takes place via part program instructions.
Protection-zone monitoring by the NC is channelspecific, i.e. all the active protection zones
of a channel monitor one another for collisions.
Definition of a protection zone
It is possible to define 2dimensional or 3dimensional protection zones as polygons with a
maximum of ten corner points. The protection zones can also contain arc contour elements.
Polygons are defined in a previously defined plane.
Expansion in the third dimension can be limited between - ∞ bis + ∞.
The following four cases are possible:
Dimension of the protection zone from -1 to +1
Dimension of the protection zone from -1 to upper limit
Dimension of the protection zone from lower limit to +1
Dimension of protection zone from lower limit to upper limit.
Coordinate system
The definition of a protection zone takes place with reference to the geometric axis of a
channel in the basic coordinate system.
