Example
Possible collision of a milling cutter with the measuring probe is to be monitored on a milling
machine. The position of the measuring probe is to be defined by an offset when the function
is activated. The following protection zones are defined for this:
● A machine-specific and a workpiece-related protection zone for both the measuring probe
holder (n-SB1) and the measuring probe itself (n-SB2).
● A channel-specific and a tool-oriented protection zone for the milling cutter holder (c-
SB1), the cutter shank (c-SB2) and the milling cutter itself (c-SB3).
The orientation of all protection zones is in the Z direction.
The position of the reference point of the measuring probe on activation of the function must
be X = -120, Y = 60 and Z = 80.
