Adding a dish carving bit to CC

[nathan32935 (Nathan Duval)]

Good afternoon,

I had done a search and found this information regarding adding a dish cutting bit from March 2021.

The answer back in March '21, was that I could add it as an end mill, but how do you calculate the feeds and speeds of a 1/2 inch bit…DOC, feed rate, spindle speed, etc.

It is for hardwood, walnut.

Origin/consistency of chipload recommendations

I’ve been going back to the basics of the whole feeds and speeds thing for a minute, and this time I want to focus on chipload values only, not the infinite number of associated RPM/feed combinations. I collected a small sample of feeds and speeds below from: usual recommand values from 3 or 4 different web sites what CarbideCreate uses the Shapeoko feeds and speeds chart for the #201, 1/4" endmills Will’s [Tableau] (https://public.tableau.com/profile/willadams#!/vizhome/Carbide3DCNCFeedsand…
