Detailed Description
2.4 Protection zones
Axis Monitoring, Protection Zones (A3)
2-30 Function Manual, 08/2005 Edition, 6FC5397-0BP10-0BA0
Reference
• Tool-related protection zones
Coordinates for toolrelated protection zones must be given as absolute values referred to
the tool carrier reference point F.
• Workpiece-related protection zones
Coordinates for workpiecerelated protection zones must be given as absolute values
referred to the zero point of the basic coordinate system.
Orientation
The orientation of the protection zones is determined by the plane definition
(abscissa/ordinate), in which the contour is described, and the axis perpendicular to the
contour (vertical axis).
The orientation of the protection zones must be the same for the tool and workpiecerelated
protection zones.
Note
During machining in operating modes JOG, MDI and AUTOMATIC, the control checks
whether the tool (or its protection zones) violate the protection zones of the workpiece.
2.4.2 Types of protection zone
Protection zones relating to machine or channel
• Machine-related protection zone
A machine-related protection zone is taken into account by all channels of the NC.
• Channel-related protection zones
A channel-related protection zone is taken into account within one channel only.
Example: Doubleslide turning machine
• The toolrelated protection zones are assigned to channel 1 or 2.
• The workpiecerelated protection zones are assigned to the machine.
• The coordinate system must be identical for both channels.
