Fanuc 18Oi controller

[waqas]

Hi,

We currently have a turning machine with Fanuc 18Oi control. We have measured the positional error in the machine in each axis using laser interferometer. Now we want to do the pitch error compensation but the problem we are facing is that the pitch compensation table is not available in the controller. Pitch compensation parameters like 3620, 3621, 3622 etc are available in the controller but the pitch compensation table (which we normally access by pressing SYSTEM key followed by pressing next menu key and then followed by PITCH soft key) is not available.

Any help in this regard will be highly appreciable.

This is a Fanuc option. You must pay Fanuc to have this available to you. Call Fanuc and they will send a service man out to install the option.
Hope this helps.

Thanks drdos for your help.

Is there any other way to carry out the pitch error compensation?

One further thing which i want to inquire is that is it a possibility that the compensation table might be hidden due to some reason?
