Nov 01, 2003 · The ballnose end mill is a special sort of tool. Its ability to mill up and down the contours of complex surfaces makes it invaluable to mold shops and other makers of 3D forms. And yet, the tool is lacking in a capability one might take for granted in other cutters: the ability to machine a flat surface. Because the ballnose tool cuts along a ball instead of a straight profile, it has distinctive characteristics

Wet Ball Mill = kg kWh = 0.16(A i-0.015) 0.33; Dry Ball Mill = kg / kWh = 0.023A i 0.5; Replacement Ball Size. Rowland and Kjos proposed the use of their equation for the determination of the initial and replacement media size. Azzaroni (1981) and Dunn (1989) recommended the use of the following expression for the size of the makeup media:

The first one takes an end mill with a corner radius milling up a slope and outputs the radius of the scallop that it creates. This phenomenon is better explained on the actual web page. This method of machining is very sensitive to runout so if your end mill has more than a few tenths of runout it will be cutting with one tooth the whole time and create a choppy non-uniform finish
Milling Formulas. Speed (RPM) = (SFM x 3.82) / D. Feed (IPM) = RPM x FPT x Z. SFM (Surface Feet per Minute) = (RPM x D) / 3.82. IPT (Inches per Tooth) = (IPM / RPM) / Z. MRR (Cubic Inches per Minute) = IPM * WOC * DOC. AFPT (@ less than 1/2 dia. WOC) = IPM x sqroot of (D / WOC) HP (Horsepower Consumption) = MRR x mf. mf - steel = 1
