PS0041 Interference in G41/G42!

saurabh.salat — Wed, 09 Jun 2021 16:33:50 GMT

I am using generic Fanuc turning post and whenever I try chamfers and/or fillets for my parts my machine always gives me an error saying interference in G41/G42. I am sure I am a newbie at this but I wanted to learn and see why this is exactly not allowing me to put chamfers on my parts. If post it without keeping "In control" it runs beautifully with all the chamfers in places. Any help is appreciated.

Thanks!

HI @saurabh.salat ,

This could be due to following reasons,

Your tool corner radius more than the minimum radius
In the controller Tooloffset, the Imaginary tool Different than the CAM
Less distance error from engaging the G42 to the point of the first move

Thanks,

Hello @KrupalVala thanks for your input.

1). I am doing a chamfer which is on outer body so the minimum tool radius should not matter

2). I checked my controller and the data there seems to be fine meaning it is the same as in Fusion.

3). I am unsure what this is, can you please elaborate the minimum distance error?

Thanks!

Hi @saurabh.salat

Try with Lead in lead out distance. Keep it more than the Corner radius.

Thanks,

It is greater than Nose Radius, my lead in and lead out are set at 2mm while my nose radius is 0.8mm.

@KrupalVala, I checked again and there is only one operation which gives me this error. I tried giving tangential extension, I removed the chamfer and I also increased lead in and lead out distances but still it gave me that error.

Hi @saurabh.salat ,

Could Please share your Fusion360 CAM project here? So some CAM experts can guide you if needed.

Thanks,

@KrupalVala I can't in public forum but if you send me a private message I can surely share the file.

Thanks!

@KrupalValais there an email or any other way to share my file rather than sharing it on public forum?

Please let me know what can be done.

Thanks!

HI @seth.madore,

Could you please look it to this case? I think the error is related to toolpath or controller end.

Thanks,

seth.madore — Wed, 16 Jun 2021 09:57:23 GMT

@saurabh.salat could you email me the project?
seth dot madore at autodesk dot com

In your NC code, which toolpath was giving this error, and what post processor are you using?

Hello Seth,

I have emailed you the file a couple of days back and explained in which operation I am facing this particular issue.

Thanks!

@seth.madore and @KrupalVala is someone looking into this still?

It's been a month and I see no updates on this. Please solve this issue.

Thanks.

Hi @saurabh.salat ,

In this case they will guide you. I suggest you to contact the controller manufacturer. Please let us know if you find any interesting or need to implement in the postprocessor or CAM.

@seth.madore Did you find something in the given project that could cause an error?

Thanks,
