# Monitoring the work space and protection space

The use of control areas prevents specific axis configurations from causing collisions between the tool and parts to be protected. A control area may be a work space or a protection space.

Control areas can be defined as three dimensional objects in cylindrical or polygonal form. The third dimension is defined by constant minimum and maximum values. Axes are assigned dependent on the currently active working plane (e.g. G17).

It is not possible to move out of a work space and into a protection space. Current tool data are included and the tool tip can be checked for validity within the control area.

Work and protection spaces are defined, activated and de-activated in the NC program. Several control areas may be active at the same time. Control areas can be redefined in de-activated state.

Work space and protection space monitoring with tool centre point monitoring is possible with

- automatic mode in conjunction with:

- Linear motion blocks
- Circular motion blocks (irrespective of their orientation G17/G18/ G19).
- Kinematic transformations
- Polynomial contours (contouring, HSC)
- Helical motions
- Reference point offsets with G92, G54
- Cartesian transformations #(A)CS available as of CNC Build V2.11.2015:

- active manual mode available as of CNC Build V3.1.3068.9: in conjunction with:

- Exclusive (G200) or inclusive mode (G201/G202)
- Kinematic transformations
