FANUC robocut - user points ?

[WEDDLETON]

I am a long time Sodick wire EDM user.
My new place of employment has all Fanuc Wire EDM`s

For years I have been using G54 - G55 - G56 - etc. for work coordinates.

Now I must conform to my new companys policy of using something called
measured points or user points.

I am told that its really the same thing , just the FANUC`s terminology,
but I don`t get it.

Can someone give me a concise explanation of this point thing.

Thanks in advance , TOM
