Table Feed Formula

TF=FPTSSZ     (Table Feed)

FPT=TFSSZ

SS=TFFPTZ

Z=TFFPTSS

Symbol English Metric
TF = Table Feed in/min mm/min
FPT = Feed per Tooth in/tooth mm/tooth
SS = Spindle Speed rev/min rev/min
Z = Number of Teeth dimensionless dimensionless

Table feed is the linear speed at which the workpiece or cutting tool moves during a machining operation.  Table feed affects surface finish, material removal rate, and tool life.  Properly adjusting table feed helps in achieving the desired material removal rate, surface quality, and tool efficiency while avoiding tool breakage or workpiece damage.
