Types Of Protection Zone - Siemens SINUMERIK 828D Function Manual

A3: Axis Monitoring, Protection Zones
2.3 Protection zones
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.
Note
If no tool­related protection zone is active, the tool path is checked against the workpiece-
related protection zones.
If no workpiece-oriented protection zone is active, protection-zone monitoring does not
take place.
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.
2.3.2

Types of protection zone

Machine-defined and channel-defined protection zones
• Machine-defined protection zone
Data for machine-related protection zones are defined once in the control. These protection zones can be
activated by all channels.
• Channel-defined protection zones
Data for channel-related protection zones are defined in a channel. These protection zones can be activated
only by this channel.
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.
