Inversion point in erosion on the path function?

If the commanded Z height is greater than the Z height of the starting point of orbiting or the commanded length is longer than the distance to the starting point of orbiting, the height or distance to go is traversed as the distance of the programmed path.

In this case, the electrode is first moved to the starting point of orbiting (see figure: even if the Z height of the starting point is smaller than the current Z height of the down channel) and then the distance to go on the path is traversed.

If no machining was programmed on the path, the starting point of orbiting is also the end point of the flushing process.
