Depth cuts are similar to Multi Passes. With multi passes you are working top down, with depth cuts you’re working from outside to inside. The roughing passes are located above the finishing passes. So if you have much material to mill, activate roughing passes. If you are closer to the final surface and you want to make thinner cuts activate the finishing passes.
The infeed from one pass to another pass is done in direction of the tool side tilt angle.
"Number" is the amount of cuts and "spacing" is the distance between the cuts
"Sort by passes" means that the machining is in layers.
"Sort by slices" means machining is in slices.
The following picture shows a machining sorted by passes. As you can see the tool moves on the same level against the drive surface.
The following picture shows a machining sorted by slices. As you can see the tool slices against the drive surface step by step.
