Obstacle

Function
If there is an obstacle between 2 position patterns, it can be crossed. The height of the obstacle
is programmed in absolute terms.
If all positions in the 1st pattern have been machined, the tool axis travels with rapid traverse
to a height corresponding to the obstacle height + safety clearance. The new position is
approached with rapid traverse at this height. The tool axis then approaches a position
according to Z0 of the position pattern + safety clearance with rapid traverse.
Procedure
Note
Obstacles are only taken into consideration if they lie between 2 position patterns. If the tool
change point and the programmed retraction plane are positioned below the obstacle, the tool
travels to the retraction plane height and on to the new position without taking the obstacle
into account. The obstacle must not be higher than the retraction plane.

Description
The tool travels in the programmed direction from the circle starting point to its end
point. You can program this direction as clockwise (right) or counter-clockwise (left).
