Sep 24, 2012· Through my experience''s, I''ve found that sticking to the manufacturer''s sfpm and cranking up the feed is normally the way to go. I use a lot of 1/8 ball nose end mills 12k rpm and upwards of 150 200 ipm. Since the finish shouldn''t be taking a lot of material off, you still need to produce a chip. Hence the high feedrates.
Milling Speed and Feed Calculator Determine the spindle speed (RPM) and feed rate (IPM) for a milling operation, as well as the cut time for a given cut length. Milling operations remove material by feeding a workpiece into a rotating cutting tool with sharp teeth, such as an end mill or face mill.

Jun 26, 2017· For ball nose optimization (and in addition to tilting the tool), it is highly recommended to feed the tool in the direction of the incline and utilize a climb milling technique. To properly employ a ball nose end mill with a tool angle and gain the most optimal tool life .
Milling operations remove material by feeding a workpiece into a rotating cutting tool with sharp teeth, such as an end mill or face mill. Calculations use the desired tool diameter, number of teeth, cutting speed, and cutting feed, which should be chosen based on the specific cutting conditions, including the workpiece material and tool material.
For example, using a 2flute, .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.
