Fanuc Wear Compensation in NX CAM?
Fanuc Wear Compensation in NX CAM?
(OP)
Hi,
I would like to have the option for wear compensation for our Fanuc 3 Axis VMC.
I have my post almost finished but I can not figure this one out.
Any ideas?
Thank you
John

Be sure you turn it on in Non Cutting Moves, More, Cutter Compensation.

That gives me the following options:
None
Final Finish Pass
All Finish Pass
I don't see "wear"?
Sorry for not being more up to speed!
Thank you for any help you can offer!

Typically G41/G42 with a D word are used for Wear compensation.

RE: Fanuc Wear Compensation in NX CAM?
I am in the process of changing software so the learning curve is steep!
I want to know what to select within the tool path/ operation to have the wear option. Within my old software I had the compensation option of either:
Computer
Wear
Reverse Wear
Off
Any help is greatly appreciated!
Thank you
John

Repeating John's question - what output are you expecting in the G code?

RE: Fanuc Wear Compensation in NX CAM?
With my my old software I had the option of selecting the options listed in my last post, that in turn would dictate the compensation. So for "computer comp" it would offset the tool within the CAM file and post the code without a G41/G42. If I wanted to engrave a stick font I would post with "off comp" and it would follow the tip of the tool without any offsets within the CAM program or on the control of the machine tool. If I selected "wear comp" it would post the G41/G42 and the offsets would then be finalized on the machine control. Hopefully I am explaining this correctly.
Not sure if I am over thinking this or not.
Here is some code:

RE: Fanuc Wear Compensation in NX CAM?
Wear in NX is tool tangent, with cutter comp. You can choose left or right for wear or reverse wear

RE: Fanuc Wear Compensation in NX CAM?
On the tool dialog you can set the Tracking Point to the tool diameter and tip. Then on the non-cutting moves you can choose to output the Contact/tracking point data.
I think this is what your looking for.

RE: Fanuc Wear Compensation in NX CAM?
Yes I was using Mastercam, where do I make those adjustments in NX?
Many thanks for everybody's help!

RE: Fanuc Wear Compensation in NX CAM?
What you call "computer" is the norm in NX. The tool CL is programmed the tool radius away from the part.
What you call "wear" is Cutcom (Cutter Compensation) in NX. The operator can adjust the path left or right of the programmed path.
What you call "contol" is Cutcom with contact/tracking output in NX. The tool contact point (part edge) is output instead of the CL. The operator enters the full radius of the tool to adjust the path away from the part.
If this is right, now you know what to search for in the help :*)

Great guessing! LOL. Yes that is correct!
Thank you
