Issue with some Feed Mill designs
Open full view...Categories: Troubleshooting MillMax
Because they exploit the b-LIM unlimited speed range (very low DOC), normally, you should see an all green dashboard. However High Feed Mills, by their design, redirect cutting forces axially so the cutting force coefficient setting for a particular material may be off. Change to Generic Materials-5 and reselect the material again. If the dashboard is all red, lower the axial depth of cut until one or more green stable speed zones appear. Select that speed.
If the tool manufacturer does not provide optimized feed rates you can use this calculator to determine the axial chip thinning feed rate:
