Fanuc 18i Offset

[applic 0]

Hi,

I am writing a cnc program to Anderson's Exxact machine which works with FANUC 18i controller.

I am using a sample cnc program which has the following lines:

I understand that G10 means offset setting for G55 work coordinate system. However, I don't know where to take the X, Y and Z values from and what is the implications of the offset setting on the cutting process.

Not sure I right understand you but perhaps this pictures can help you

Its was taken from different manuals and as you can see with different explanation
