4.2 Protection zones
4.2.1 Definition and activation of protection zones
Requirement
The following internal protection zones are to be defined for a turning machine:
• One machine- and workpiecerelated protection zone for the spindle chuck, without
limitation in the third dimension
• One channelspecific protection zone for the workpiece, without limitation in the third
dimension
• One channelspecific, toolrelated protection zone for the toolholder, without limitation in
the third dimension
The workpiece zero is placed on the machine zero to define the protection zone for the
workpiece.
When activated, the protection zone is then offset by 100mm in the Z axis in the positive
direction.
