Fanuc 18i - T "measure"

[chowquoe^]

Hi gang.

 

Having a problem on a Daewoo lathe w/ 18i control. When the measure button is used it is not outputting what one would expect. Example---

 

Z0 > measure = value entered in offset is "0"

Z0.100 > measure = -.100

Z-.100 > measure = .100

 

ant thoughts on how to correct this little PITA of a problem?

 

Thanks in advance.

Is there anything in your work shift offset? Is there an active G54-59 offset?

Yes, there was; I removed the offset and retried to "measure". I got the exact same result.

I think you are talking about work shift in Z. It took me awhile to get used to it but this is how our Hardinge lathe works . The number that goes into your work shift in Z is negative the distance that the stock is out from machine "0". The face of our spindle is Machine "0" so if the stock is sticking out 1" from there, the work shift offset is Z-1.000.

No, I'm talking about the tool offsets. Say I turn a piece of material to 1.00" go in to the geometry page to the tools number an type (X 1.) measure it give me a negative 1. If I use X (INP. C) then -1. (+INPUT) it will give me the disired result. It just the "long" way around IMHO. Hope that helps clear it up; sorry for not being a bit more detailed. I wish I was standing in front of an elite

Well, I'm not sure if I get your problem, but this is what it sounds like to me.

 

If you are at Z0 and you tell it Z-.100 measure, you are telling the machine that Z0 is -.100 from where you currently are, and you are currently at .100
