what are the preferred rpm, feed rate, plunge rate so that i can configure my CAM software?

I use trial and error on tapered BN bits as the geometry varies from the tip as you move up the bit. For 3d carving I will run a roughing pass first, then change to the TBN and start at about 2 IPS for both feed and plunge and move towards 3.5. I will start my rpms at 12k and go up or down. Whatever tip size, I generally use 10% stepover. As I run test passes on the wood type I am using I listen for any stress or chatter. As I finish the run and the bit stops spinning, I verify that it is not hot to the touch and finally view the test carve for results. Again, this is my process for any size TBN.

Is there a SpeTool database?

Yes, there is just go to SpeTool website and you can download the database for Fusion 360, Vectric, and others there.

How many inches per minute do you run with this mill? my no load rpm available are 8,000-24,000 rpm. any suggestions appreciated

I do 18000rpm in my cnc and find it leaves a nice cut on hard woods

What are the general speeds, spm, and depth for this bit for oak carving, for fine detail ? I am just starting out. Thanks for any info. jc

I can't give any suggestions because I don't know what machine you have, spindle or router, horsepower nor it's rigidity.
