Roughing vs. Finishing End Mill: How Do They Differ?
Roughness on the surface is caused by scallop marks similar to saw teeth. The feed rate is the only factor directly responsible for surface roughness other than tool geometry. The surface finish of a product can be negatively affected by a higher feed rate. A higher depth of cut also degrades surface finish and machining accuracy.

The milling process – definitions Cutting speed,v c Indicates the surface speed at which the cutting edge machines the workpiece. Effective or true cutting speed, v e Indicates the surface speed at the effective diameter (DC ap).This value is necessary for determining the true cutting data at the actual depth of cut (a p).This is a particularly important value …
Finish pass speed and RPM?
That heats the tool and radically reduces tool life. Too many rpms (too much surface speed) and you'll kill tool life as well. The chart is from my course on feeds and speeds: CNC Milling Feeds and Speeds Cookbook and Tutorial Lots more there to help figure out these simple cases as well as much more complex cases. Best, BW

What is Cutting Speed,Feed,Depth Of Cut in Machine tools
The depth of cut is the distance that the tool bit moves into the work. usually measured in thouhs of an inch or millimeters. General machine practice is to use a depth of cut up to five times the rate of feed, such as rough cutting stainless steel using a feed of 0.020 inches per revolution and a depth of cut of 0.100 inch. which would reduce the diameter …

Teflon Machining: Tolerances, Speeds, Feeds & Is PTFE Easy …
– Cutting speed: The cutting speed for machining Teflon should be relatively slow, typically around 200 to 400 surface feet per minute (sfm). This helps to avoid excessive heat buildup and melting of the material. – Feed rate: The feed rate for machining Teflon should be relatively low, typically around 0.001 to 0.004 inches per …
Feeds and Speeds for cutting graphite?
I need to cut 264 inches, that's 22 feet, of slot .010" wide in Poco 3 graphite. Normally I cut details on a CNC mill using miniature carbide end mills, but the thought of trying to cut that much slot with a .010" end mill leaves me cold, so I plan to use a slotting saw. I have no idea what to use for feed and speed.
Machining Guide for Engineering Plastics
Two flute end mills, face mills and shell mills with inserts as well as fly cutters can be used. Climb milling is normally recommended to help reduce heat by dissipating it into the chip, and melting and poor surface finishes are minimised. See table below for tool geometry, cutting speeds and feeds. Drilling
