On my mid 90s cincinatti arow it runs out of contouring accuracy at elevated feedrates before it runs out of rpm with a 12 coated carbide end mill, anyway.I let gwizard calculate the speed and feed ratio required to maintain chip thickness for cutter longevity too thin of a chip promotes rubbing and tool edge wear then scale back the.

View AllThe 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.
View AllThrough my experiences, ive found that sticking to the manufacturers sfpm and cranking up the feed is normally the way to go.I use a lot of 18 ball nose end mills 12k rpm and upwards of 150 - 200 ipm.Since the finish shouldnt be taking a lot of material off, you still need to produce a chip.Hence the high feedrates.
