Terms

IPM = Inches Per Minute I PR = Inches Per Revolution RPM = Revolutions Per Minute SFM = Surface Feet Per Minute D IA = Tool Diameter

Formula

Inches( decimal)
mm( metric)
RPM = SFM x 3.82
DIA
RPM = M / min x 318.47
DIA
IPM =
RPM x IPR
mm / min = RPM x mm / REV
SFM = RPM x DIA
3.82
M / min =
RPM x DIA
