Need Help!- Machine Face + OD, Flip part around, face to length and machine the rest.

Machine Face + OD, Flip part around, face to length and machine the rest.

I have been wondering how do you guys program and set-up this flip part around thing using the same work shift.

I found some difficulties, I figure that if the part projection is the same on both sides it will work with the Z0.0 but when one side sticks out more than the other it won’t work.


Any inputs please

You could try and program the whole thing from the "stop" out, and all of your Z's (I'm assuming a lathe) will be positive, and your Z zero is the stop face.

hum!!! Yes a lathe, fanuc...
That could work yes indeed but I'm afraid that system would create some difficulties to some of the operators.

Any ideas on how to using a imaginary work shift on the lathe?

Thanks

You could also use 2 sets of geometry offsets: T0101 for the first side, T0121 for the second side. Of course that's assuming you have geometry offsets.

Hi, We turn both ends of component frequently. Why not have 2 offsets ie G54=1st end, G55= 2nd end.

Both are good ideas,
Using G54 and G55 is not an option; my machines [Nakamura-tome fanuc] do not have that option, only one work shift…
for what I know.

I was wondering that I could create some sort of an imaginary work shift, like a macro location.

Any ideas?

Thanks

I believe you could use G10 to set the work shift at the start of each half of the program - if you have the option. You don't say what model Fanuc you are running.

I do have 18-t, 21-tb, o-t, m5

I have other machines with live tooling that allow me to use G54 etc...

How would the G10 work?

As I look through the 21T-B manual, I can't find a command for setting the Work Shift. Could be I was mistaken about that.

Let's try the User Macro route. Just for the heck of it, try this command in MDI:

#2601=9.9999

See if the Work Shift value changes to 9.9999, or if you get an alarm.

Dcoupar, looks like I got it to work, with your help of course..

I went to this Fanuc 18-T
MDI / #2601=9.999 / start and the Z value on the work shift changed to 9.9990

So I can use this User Macro route to flip parts around and etc..
Nice going Dcoupar

Thanks
Have a good weekend

Glad it worked out. Enjoy the weekend.
