Lathe canned problem

[Don S at Barefoot CNC South]

Hi

I am getting an erroe mesage:

Canned finish profile does not match canned rough profile. Pattern recall is not possible.

I am using MC 9 all latest updates. This comming up with all post proceesors, I thought it was a post problem. The only time I don't get it is when I use the exact same tool for rough and finish cycle. Has anyone else seen this?

Thanks

Are you sure your posts support canned cycles?

Also,do you have the misc integer set correctly?

[Don S at Barefoot CNC South]

Hi

Yes post supports it tird MPLFAN post as well

And misc values are set right it is happening on all jobs I try to use canned cycles since the last update to ver. MR0904

Thanks

I maybe off here, but make sure the tool nose radii are EXACTLY the same value, MC won't allow you to use different radii between rough and finish when using contour roughing cycles (G71,G72 for rough and G70 for finish)

Hi

Radius on both tools are the same.

Don S,

 

Also make sure the chain for the cycles is exactly the same. If the chain isn't using the same entities, you'll get the error message you've described. HTH

Hi

It is using the rough op NCI for the finish pass.

Thanks

Hi

I think I figured it out. You can not use the plunge parameters in canned rough, because that option is not on canned finish tool path. I don't understand why if its on the rough it should be on the finish cycle as well. Maybe someone could verify that this is whats causing the problem?

Thanks

Hi

Are there any lathe people that can verify this problem?

 

Thanks

Hey Don

 

I turn parts with MC all day but I don't use this toolpath option. If you want to email me your file and tell me what the problem ops are I'll run it here to rule out a .dll problem or something on your box

Hi

Has anyone tried to verify that you can not use plunge parameters when using canned rough and finish paths on MC lathe?

 

Thanks

CNC Lathes won't plunge turn in canned cycles, at least none that I've seen; they want steadily increasing or decreasing numbers

Don S,

I did a quick path with different plunge choices and it seemed to work fine. (no error on finish pass)

Don S.

I did the something as JG

Different plunge cut parameter, different radius, and different insert (80deg for roughing & 35deg for finish)

 

It works fine no error

 

(If you use an 80deg insert and set your plunge cut parameter to no plunging allowed and try to finish with a 35deg insert even do the insert might have clearance to do an under cut

The tool will follow the no plunging allowed profile from the roughing pass.)

Guess I misunderstood the question; D'oh!
