Dynamic spindle-speed and feed-rate for ball
For example, using a 2-flute, .250" ball end mill at 980 sfm with a .002" ipt chip load, and a .020" DOC (axial and radial): When the endmill is parallel to the surface (cutting with the side), I get a 15,000 rpm spindle speed, and 111 ipm feed rate.

Mill (grinding) - Wikipedia
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

how can we calculate the rpm of ball mill
Dynamic spindle-speed and feed-rate for ball end mill 3D finishing Finishing 3D surfaces with a 3-axis machine and a ball end-mill can be challenging. In a single op you can have the ball engaged near the tip where the SFM is much lower and other times engaged near the side where it behaves more like a straight endmill -- and anywhere in between.
