Safe — The tool moves to the safe area before making the link move.
Incremental — The tool descends at rapid feed from the safe area to the specified incremental distance above the target point, and then plunges the remaining distance. If you have a multi-axis toolpath, the tool retracts a set distance along the tool axis and then retracts to the safe area. It comes down from the safe area and completes the approach along the tool axis. The distance moved along the tool axis is controlled by the Incremental plunge distance on the Moves and clearances tab of the Toolpath connections dialog.
Skim — The links traverse clear of the part by the specified incremental distance, descend at rapid feed to the specified incremental distance above the contact point, and then plunge the remaining distance.
On surface — The links follow the surface of the triangulated model, and so prevent gouging.
Stepdown — The links traverse clear of the part by an amount, so that with the specified stepdown the vertical descent will reach the next contact point.
Straight — Straight-line moves are used. These straight moves between raster paths could cause gouging over curved areas of the model.

Circular arc — the tool moves are circular.
