How many feet per minute in a meter per minute: If v m/min = 1 then v ft/min = 3.2808399 × 1 = 3.2808399 ft/min. Sign up for our eNewsletter now to stay in-the-know. (in.

When the diameter (of part or tool) is 3.82". 66 Granby Street, Bloomfield, CT 06002 Surface Feet Per Minute to Revolutions Per Minute Calculator : Fill in Two Items and Press the Button to Find the Third. (IIRC, 4 is just an approximation used for Pi) SFM is close to the formula your programmer gives, but is actually: diameter x .2618 x RPM = SFM

Go until your snap it off and then back off just a touch. browsing data or IP addresses) and use cookies or other identifiers, which are necessary for its functioning and required to achieve the purposes illustrated in the cookie policy. It is expressed in units of distance along the workpiece surface per unit of time, typicallysurface feet per minute(sfm) ormetersperminute(m/min). Resulting Surface Feet Per Minute: SFM m per min . The Revolutions Per Minute formula is correct, but not for Surface Feet per Minute as you say: 4 x Cutting Speed / work diameter = RPM. How to convert meters per minute to feet per minute [m/min to ft/min]: How many feet per minute in a meter per minute:If  vm/min = 1  then      vft/min = 3.2808399 × 1 = 3.2808399 ft/min, How many feet per minute in 74 meters per minute:If  vm/min = 74  then      vft/min = 3.2808399 × 74 = 242.7821526 ft/min.

Surface Speed is the speed difference (relative velocity) between thecutting tooland the surface of the workpiece it is operating on.

Its most common use is in the measurement of cutting speed (surface speed) in machining. Speed – Surface Feet per Minute (SFM) Feed – Inches per Minute (IPM) Feed per Tooth (FPT) Adjusted Feed per Tooth – Chip Thinning (AFPT) Feed per Revolution (FPR) Depth of Cut (DOC) Width of Cut (WOC) Tool Diameter (D) # of Teeth in Cutter (Z) Metal Removal Rate – Cubic Inches per Minute (MRR) Actually, there is ONE case where SFM=RPM. Its most common use is in the measurement of cutting speed (surface speed) in machining. The latest industry news—straight to your inbox.
