Is there a code to do this?

[MIL-TFP-41]

One of the lathe guys just asked me a question....Is there a code that will stop the machine but leave the spindle on? They want to sue it to deburr & polish threads.

 

All the machines are Mori's with various Fanuc controls.

[Mgrenier]

Can you just dwell the machine for a specified amount of time usine G04 P...?

 

Or you could try putting a feed of F0.

 

I have not tried any of these but it might work.

Does M1 Stop the spindle?

[MIL-TFP-41]

Both M1 & M0 stop the spindle. The problem I see with the F0 would be that you would have to hit reset to stop the machine. Dwell could work....however not every operator deburrs/polishes in the same amount of time.

Keep the manual spindle start/stop in the hands

of the operator. Trying to mix cnc and manual ops

is a dangerous game to play with someones life.

Yep. Been there and tried to do it. It just doesn't work. I still have all my digits, they're just really scarred up now.

This is what I've always done. Put in a M00, then let the operator turn the machine to manual, then when their finish turn back to automatic and carry on.

 

Just whatch those fingers when deburring that way

[Mic6]

What does the de-burring entail? Filing an edge, or wrapping their hand with scotch bright around the part?

[MLS]

Build a loop macro with dwell so it cycles the dwell in a closed loop without the block delete on.

 

As soon as they are done, they can turn on block delete and cycle out of the dwell loop then carry on.

[Bruce Caulley]

Don't want to sound like an arse, but that is a practice that is not only dangerous, but with the right tools is not necessary.

+1 to hardmill and Bruce. Don't do it.

What would the coroner say about this?

Hey you asked

[Rob @ Target Machine]

I have to agree with Bruce.

 

Don't ask operators to do manual finishing in a lathe.

 

Program using some burr-less machining practices. Bench polishing is exactly that, a "bench" operation.

 

A couple years ago, I had to bring one of my operators to the ER. The owner wanted him to polish parts in the lathe manually, and without a doubt, it only took 2 weeks for him to get bored, lazy, tired, or whatever.

 

The end result was a slip, 4 severed fingers, a lawsuit, and a workman's comp claim.

[Dave.L]

I agree it's a bad idea. For the time that polishing is required (and a rotating part) their are other ways, like collet chuck polishing lathes that make it difficult to get caught on anything that will hurt you.
