Function
If there is an obstacle between 2 position patterns, it can be crossed.
The height of the obstacle can be programmed absolutely or
incrementally.
If all positions in the 1st pattern have been machined, the tool axis
travels in rapid traverse to a height corresponding to the obstacle
height + safety clearance. The new position is approached in rapid
traverse at this height. The tool axis then approaches a position
corresponding to Z0 of the position pattern + safety clearance.
Positions >
Obstacles are registered only 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.
