HSS (high-speed-steel) tools. For carbide-tipped tools, speeds can be twice those given. Carbide-tipped tools do not operate properly at low speeds; operate at or above the minimum speed if possible. To calculate rpm from sfpm: rpm = 3.8×speed d ∼ 4×speed d where speed is given in sfpm and d is the diameter of the tool (mill or drill) or

The Speeds and Feeds Calculator uses the following formulas: RPM = (12 * Surface Speed) / (PI * Tool Diameter) [revs/min] Feed Rate = RPM * Chip Load * Number of Teeth (Flutes) [in/min] Where PI is the constant (3.141592654). Reference: Erik Oberg, et.al. (2008).
NOTE: Varying conditions can easily require adjustments. • Feed equals .001" per revolution for every 1/16" of drill diameter, plus or minus .001" on the total. • Speed equals 80 surface feet per minute in 100 Brinell hardness material and the speed should be reduced 10 surface feet per minute for each additional 50 points Brinell hardness.
The rules and principles of cutting speeds and RPM calculations apply to all of the operations being performed on drilling machines. An example of this would be reaming. Reaming is done at half the speed and twice the feed as drilling. This rule still applies on the drill press as it does on the milling …

To do this, we'll need to add some material data to come up with realistic feed rates. Let's say that we're cutting 4140 HTSR. We'll use a cutting speed of 400 SFM for standard machining. Let's see what that stock removal looks like. For conventional machining, the RPM works out to 3200 RPM.

Feeds and speeds. The constant question that will never die. It's hard to answer this in a simple blog post. Don't take this as the end all, be all, but more of a starting or reference point. There's a whole lot of math that goes into finding the perfect feed and speeds.
Feed rate: Reduce feed rate by 50% when entering and exiting a cut to reduce the shock of the interupted cut. Effective cutting edges: When calculating feed rate, use the effective number of inserts specified for the cutter. For staggered tooth slotting, this is 1/2 the total number of inserts.
