Thanks mate, I`m gonna bookmark that one for future reference

Hmm, watched a couple of vids on the 'tube, played about a bit and managed to recreate the back plate for the Z-Axis drive on my bridgeport conversion project, previously made via 2d cad.



With a couple of years practice, i might just get the hang of F360 after all ;)

This took me about 2 hours.

Ok, simple task, used to do it manually by guesswork mainly ;)

I have a block of metal, rough-sawn on two edges, say i need to make this exactly 50mm wide from these two edges.

Square and clean up one edge by doing a facing pass on it but remove just enough to clean it,
Zero the Z axis on the base of the vise or whatever the part is held in,
Rotate the part and run a pass or passes to arrive at Z50.00

Is that a reasonable plan for a seemingly simple task?

Rotate the part and run a pass or passes to arrive at Z50.00

Do you mean Z-50?

Do you mean -Z50?

No, he means Z+50.

His reference for Z0 is the base of whatever holds the work piece, i.e. the bottom of the work piece. First time surfacing only, after that turning the work piece around and referencing Z0 to the surfaced side (now the bottom of the work piece) and lifting the Z to Z+50 to get the work piece exactly 50 wide. If he needs to cut far too much then he lifts Z over 50 and uses as many passes as necessary to arrive and stop at Z+50. At least if he is doing it the way I do, and the way I interpreted his words.

[Davek0974]

Excellent, yes it would be Z50 as ref is the base on the last setup.

Thanks again :)

How many feed rates do we all use for the same tool?

Using my freed-rate calculator i get different feeds for slotting or profiling, even though the tool may do both types of cut in the same part.

So, set different feed rates for each process or take the worst case (usually slotting) and stick with that rate??

That's the way I do it as well, but I am just an amateur.
