Best way to create tool library

[jeffescott]

I have a spindle that is good for 24000rpm.  I recently learned that the Fusion Tool Library has an artificial cutoff of 12000 rpm.  This of course mostly affects tools 1/4 in and down, which is shat I mostly use.   Up until now I have been working mostly aluminum, i am familiar with the feeds and speeds I need.

Now I am starting to use various materials 6061, 7075, Steel, O1, titanium g5, UHMW, Teflon with 1/4 inch and down bits.

I am relying on the fusion suggested feeds and speeds.

But really i need to update a tool library that includes, the uprated speeds, for small tools.

What is the best way to make this happen, and where and how do I store this updated library.

Hi @jeffescott,

I'm not totally sure what artificial cutoff you're referring to. You can enter any value that you like into the Spindle Speed parameter, including 24000 🙂 

This area of the tool edit page, the Cutting Data tab, is where you can manage multiple sets of feeds and speeds per tool, as makes sense for the kinds of tooling that you have. You can create many presets per tool, and you can even copy and paste them across tools. 

I might recommend checking out the product documentation for Presets which will get into some more detail about what you can do here: https://help.autodesk.com/view/fusion360/ENU/?guid=MFG-CREATE-TOOL-PRESET

The Fusion Sample tools have much better starting points that the default feeds and speeds when you create a tool. I would also suggest looking at the site of the vendor you got the tool from, as they can offer tables or calculators with which you can get starting feeds and speeds that are more specific.

In terms of making the tool library accessible for reuse, creating a new library in the Local or Cloud area will make it available no matter what document you are working on. If it's important to you for it to show up across multiple computers, I would recommend putting it in the Cloud section which will store it in Fusion Team like your CAD designs. 

Hope that all helps!

I guess what i am asking is 

say i have 1/4 bit and the speed in the selected material is say 7600 rpm.   When i go to the 1/8 bit the speed is 11999 rpm.  If you were to maintain the sfm the same as the 1/4 inch bit the speed should be 14200 rpm.   So i increase the rpm.   But for that rpm.  I should have an increased feed.   I guess i should maintain a constant feed per tooth.  
Is this the proper math.

So then i do this for say each bit and material manually. That is may be 30 times.

So i  save each tool to my personal library and then upload that to the cloud?

Are you referring to the generic tools that are included with Fusion? When those were created, a decision needed to be made as to what parameters would be observed. Given that most (common) commercial machines do have a spindle cap of 10 or 12k, it was decided to cap the speed at 12k. 
Yes, technically, the SFM is a constant that should be observed. However, when one runs into the spindle cap, the SFM needs to drop accordingly.

The tools that are in those libraries are guidelines and should most certainly be viewed as such (copied over into your cloud library, or created anew)
