# Finishing path question

How to run a finishing path on this example?

Using the rough pass, say I create 3 squares cut into stock. Each square is at a different depth.

Say I use a 3mm bit to rough and choose to leave 0.1mm stock for the finish pass on all squares.
For the finish say I use a 1mm bit.

When running the finish pass, do I select all 3 squares and run them at once, or should I run them individually because they were cut at different depths during the rough pass?

When selecting a square to run a finish pass, my guess is that the software is reading the depth of that square, then telling it to cut 0.1mm more. If this is true then each square I select will be telling the software what the depth is on each oneâ€¦ so I would select all the squares to run the finishing pass at onceâ€¦ correct?

Thanks

For efficient machine movement youâ€™ll want 3 separate toolpaths, each starting at the appropriate depth.

Thanks for the reply.

So, a separate finish pass for each square? (there is already a separate rough pass to get the different depths),

My guess is that the software reads what is selected, then cuts the amount that particular rough pass told it to leave. â€¦ but it can only read one selection at a time, or one calculated finish amount to cut (in this example 0.1mm)

thanks

If youâ€™re using 3D toolpaths, then the finish path is just cutting to the finish depth. It doesnâ€™t know what depth or how much stock the rough path left. Thatâ€™s up to you.
The rough path just adds the â€śStock to Leaveâ€ť to whatever the 3D model depth is.

If using 3D Finish, I see no reason why you need to separate them. Itâ€™s getting the depth from the model, and should cut each square to itâ€™s finish depth.

If youâ€™re 2D machining, I totally read this wrong & youâ€™ll want separate paths for each depth.
The software still has no idea what the previous depth was, so you need to set the start & max depth accordingly.

Ahhhâ€¦ OK
That seems rightâ€¦ the model determines the depth, A single pass with the rough or finish would work (using 3D only)
thanks
