Definition via part program instruction
General
A protection-zone definition must contain the following information:
• Protection zone type (workpiece- or tool-related)
• Orientation of the protection zone
• Type of limitation in the third dimension
• Upper and lower limits of the protection zone in the third dimension
• Activation type ("Protection zone immediately active": only possible via system variable)
• Contour elements
Definition of protection zones
The following systematics must be maintained in the definition of protection zones:
• Definition of the working plane:
G17
,
G18
or
G19
• Definition beginning
- Channel-specific protection zones:
CPROTDEF(...)
- Machine or NC-specific protection zone:
NPROTDEF(...)
• Contour description for protection zone
• End of definition:
EXECUTE(...)
Definition of the working plane
The desired working plane to which the contour description of the protection zone refers must be selected with
G17
,
G18
,
G19
before start of the definition. It may not be changed before the end of the definition. Programming
of the applicate is not permitted between start and end of the definition.
Definition beginning
The definition start is defined by the corresponding subroutine:
•
CPROTDEF(n, t, applim, appplus, appminus)
•
NPROTDEF(n, t, applim, appplus, appminus)
Parameters Type
