There are some things to keep in mind when you define an exclusion zone (Insert | Move | Exclusion Zone menu option):
In the measurement routine, you need to have a MOVE/EXCLUSIVE_ZONE command before each section of commands that move either arm into the overlapping region of the dual arm volume. The MOVE/EXCLUSIVE_ZONE command should define a 3D box around all the motion that is about to be commanded in the overlapped area of the dual-arm CMM.
There must be a MOVE/EXCLUSIVE_ZONE=OFF command after the probe has been withdrawn from the overlapped part of the dual-arm CMM.
For example, if you want each arm to check a common sphere using automatic sphere commands, you should set up the measurement routine like this:
MOVE/EXCLUSIVE_ZONE=ON
(for Arm 1)
AUTO/SPHERE (for Arm 1)
MOVE/EXCLUSIVE_ZONE=OFF (for Arm 1)
MOVE/EXCLUSIVE_ZONE=ON (for Arm 2)
AUTO/SPHERE (for Arm 2)
MOVE/EXCLUSIVE_ZONE=OFF (for Arm 2)
The following steps describe how to define the exclusion zone.
