It seems like the speeds and feeds page has totally changed format and really reduced the aggressiveness of suggested cuts. That’s fine but I’d like to have a file that reflects Sienci labs recommendations…
100% agreed!! I would like to buy some Sienci bits but I’m hesitant to do so until there is complete recommendations for LM and Altmill for DOC, step over, and feeds and speeds and also reviews by those who have purchased and used the bits. Tool Libraries are needed.
@thankjun I could write reviews of Sienci bits, Joe, but I suspect that they would not satisfy your request. Stepover depends entirely on not only the material that I am cutting, but the project that I am working on. For example, if I am simply doing a rough pocket in maple using a 1/4" DC end mill, my DOC, stepover, feed and speed will be completely different from doing the same roughing pocket in MDF or acrylic. Similary, if I am then cleaning up that pocket with the same end mill, all those specs will vary depending on how much material I left with the roughing pass.
Add in the question of direction of travel vs grain direction and there are simply too many variable for any review of mine to be of any use to you.
I was about to suggest that, until you gain experience and confidence in setting these variables, you stick with bit suppliers like Amana or Whiteside. However, a quick look on their sites this morning showed that they don’t provide the specs you want, either.
Having told you that I can’t help, I’ll try anyway. IMHO, a good place for you to start will be to find a good chip load calculator. There are dozens on the net. Using that, you will easily to be able to plug in the variables that you want. Over time, and with successful projects under your belt, you will be able to enter these values without outside help.
Thank you four your responses.
The primary reason for my post is that for bits, Sienci is competing with other companies which, it seems to me, are doing a better job of promoting their bits. Amana, Whiteside, SpeTool, Jenny Bits (Cadence Manufacturing), IDC Woodcraft, CIC Workshop, etc all have Tool Databases for Vectric software. For Whiteside bits, it at Whitesiderouterbits.com under Downloads. Amana’s is at https://www.amanatool.com/cnc-tool-databases-for-fusion-360tm-vectric and so on. At least one of these companies has an app that gives feeds and speeds for various wood species. Many of these companies make it possibly for bit buyers to post their evaluation or opinion of the bits. I know that some are not buying Sienci bits because such information is not available for Sienci bits.
There is for some bits significant variation in recommended feeds and speeds between the bit selling companies. Examples include roughing bits and V bits. I may be wrong but I expect that many buyers look to see what the specifications are for bits they want to buy. Personally, I’m looking for an extended length roughing bit and a new 60 degree V bit. I will likely buy from another company than Sienci because I can read reviews from others experience, even though I know my experience may be very different. I don’t know how Sienci’s V-bit compares to Whiteside’s or CMT’s that is what Vectric uses in some of the projects I want to make, or how Sienci’s roughing bits compare to IDC Woodcrafts which is both cheaper than Sienci’s and offers a 90 day replacement. I very likely would be buying some Sienci bits if there was more information and favorable reviews. Maybe I’m different from others.
I do appreciate that in the Feeds and Speeds Sienci does provide, they give different values for a pocket pass vs a profile full width pass.
Thank you again for your suggestions. I will be doing more bit testing and evaluation.
I readily admit that I have not done a systematic or detailed evaluation of many of my bits or comparisons for same bit type, but I do check the built in chipload calculator in VCarve Pro.

@thankjun This thread was started over a year ago and the OP was asking about a tool library for Fusion 360.
For my clarification, you are not using Fusion. You are using VCarvePro, so your interest is in a tool library for that application, correct?
Also, to follow up on my advice to find a chip load calculator, I should have been more clear. In of itself, the chip load calculator, like the one built into VCarvePro is not the answer to your question. You also need to find a chart that you trust that tells you the chip load range that is optimal for the material you are cutting.
As this is a user forum, I suggest that you contact Sienci directly to suggest that they develop what you are looking for.
Correct regarding Vectric vs Fusion 360. I searched for tool library and if I recall correctly this was the only one that was found within the last year.
I just realized that Sienci does have a tool library not only for Vectric software but also Fusion 360 and CarveCo and have had it for years. It’s under Resources for the Longmill MK2. However, it does not have data for the new bits such as roughing bits. Recommendations appear very conservative compared to other tool databases.
@thankjun My apologies. I assumed that you knew about that one as it has been on the site for some years now.
As for being conservative, they say that on the page. That’s the problem with publishing these things. There will always be those who says that they are too conservative or too agressive. I suggest that, if you decide to the Sienci chart, take it as a starting point. Experience will tell you what works best for your bits, your material and your projects.
Edit. I’ve changed the title of this thread to something more relevant as it no longer has any relevance to Fusion 360 and the original post has gone unanswered for over a year.
I’ve also moved it to the Vectric category in software.
