Tool change point, which must be approached by the revolver with its zero point.
WCS (Workpiece Coordinate System)
•
MCS (Machine Coordinate System)

Notes
The tool change point must be far enough outside the retraction area that it
•
is not possible for any tool to protrude into the retraction area while the
revolver is moving.
Ensure that the tool change point is relative to the zero point of the revolver
•
and not the tool tip.
