2D/3D protection areas

2D/3D protection areas

Function

For the elements to be protected, 2D or 3D protection areas are defined in the part program or via system variables. These protection areas can be activated and deactivated in the part program. Protection areas must always be divided into workpiece-related and tool-related areas. During machining in JOG, MDI or AUTO CNC operating mode, a check is always made to see whether the tool or its protection areas violate the protection areas of the workpiece.

Monitoring of the protection areas is channel-based, that is, all active protection areas for a channel are mutually monitored for collisions (protection areas not channel-specific with NCU system software for 2/6 axes). A maximum of 10 protection areas and 10 contour elements are available for describing a protection area.

The 3-dimensionally programmed protection areas are displayed in 2D. This display also applies to the programmed working area limitations.

Benefits

Protection areas can be used to protect various elements on the machine and its equipment, as well as the workpiece to be created, against incorrect movements.

Some of the elements that can be protected are, for example:

• Fixed machine components and built-on accessories
  Tool magazines, swiveling probes
• Moving parts belonging to the tool
  Tool carriers
• Moving parts belonging to the workpiece
  Mounting tables, clamps, spindle chucks, tailstocks
