How to set this tool up in Fusion360?

[kamil.malec94]

Hello,

I'm trying to set up a new turning tool in Fusion360. 

Tool link: EDP: 6211513 - Part Number: SFXCN16-4.9D - Series: SFXCN (ingersoll-imc.com)

I struggle to get the insert correctly aligned. It's currently 90 degrees "off".

Also, the usable length of this tool is 1.26", how do I adjust the holder type to work correctly. I'm roughing some 2.50" deep pockets, and need the holder to be correct geometry. 

Is there a way to manually import this tool? I'm not sure if I can get a step file though; the website do not show step file available. Would probably need to sketch it. 

Thanks in advance, 

Kamil.

Sadly, the tool library is extremely limited in regards to lathe tooling. A couple of the limitations, as they apply here;

1) Not possible to import a solid model of lathe tooling at this time

2) Not possible to define that tool exactly as it is, but we can get close:

Seth, appreciate this a lot! 

How close are we with this tool (+/-) to the original geometry?

The good thing is that we only use this tool for roughing operation with finish stock allowance.

Truthfully, I'm not sure. I looked at the image of the tool and did some quick calculations to determine angles and sizes, and that's what I came up with. I suggest double checking my math and confirming for yourself 🙂

Seth @seth.madore , I'm trying to rough out the cavity, but this tool is not letting me cut what I want it to cut. Any suggestions? 

[seth.madore]

Could you share your most recent Fusion file?

[kamil.malec94]

there you go. It's a file for a part I programmed 2 years ago. We're trying new roughing tools now and want to do additional toolpaths. Not sure if that is why it's not generating correctly.

At the moment, I don't think there's going to be a solution in Fusion. I'll send this along to one of the developers and see if they have any thoughts on how to overcome this...

[kamil.malec94]

Got it. usually in situations like this I just modify my model to allow tool geometry to access the spots I want to machine. I manually sketch out a point and select that as my zero. 

Also, I think if this tool was set up as a grooving tool, we would be able to machine these cavities, however I don't think it's possible to apply this geometry for a grooving tool. 

Thanks for help and I'll be on the lookout for any possible updates from your developers. 

Best,

"Also, I think if this tool was set up as a grooving tool, we would be able to machine these cavities, however I don't think it's possible to apply this geometry for a grooving tool. "

You can set it as a Grooving tool, but it will not perfectly generate the stock removal in simulation

Think of it like a high feed milling cutter, they have a similar geometry that cannot be replicated in Fusion(or most other cam software)

instead the inserts have a "Programming radius" and you set them up as a Bullnose cutter in Fusion.

You could do similar with this tool as a Grooving tool with a large radius.

I cant find any reference to the "programming Radius" on the Ingersoll website, maybe your tooling Rep can help you out

@a.laasW8M6T thanks for the idea. It's the only possible solution that I can think of. The geometry is quite a bit off though. I sketched the actual insert geometry and then overlapped it with the geometry of the tool that I set up (grooving, square, with corner radius). 

Let me know if you think there's a better way to set this tool up. 

I attached the tool file as well. 

[a.laasW8M6T]

Yea I think that should work correctly, If you are only using it for roughing it should be fine, you will end up with a little extra material than what is shown(in simulation)in sharp corners.

Just like with a High feed mill, you may need to take some semi finishing passes with the finishing tool to remove those bits.

I would still test it out on a scrap piece of material to make sure your not getting any over cutting anywhere, I dont think you will but just to be safe.

@a.laasW8M6T Thanks a lot for your help on this. We'll be running this tool later this month. I will come back and give you an update on how the tool performed.
