Formula Used

Cut Velocity = Machinability Index of A Material*Cutting Speed of Free-Cutting Steel/100
V_cut = I*V_s/100
This formula uses 3 Variables

Variables Used

Cut Velocity - (Measured in Meter per Second) - The Cut Velocity is the tangential velocity at the periphery of the cutter or workpiece (whichever is rotating).
Machinability Index of A Material - Machinability Index of A Material is used to compare the machinability of different materials by quantifying the relative machinability of a different materials.
Cutting Speed of Free-Cutting Steel - (Measured in Meter per Second) - Cutting Speed of Free-Cutting Steel is the speed of cutting used when operating on a standard workpiece made of standard cutting steel.

STEP 1: Convert Input(s) to Base Unit

Machinability Index of A Material: 125 --> No Conversion Required
Cutting Speed of Free-Cutting Steel: 0.666667 Meter per Second --> 0.666667 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

V_cut = I*V_s/100 --> 125*0.666667/100

Evaluating ... ...

V_cut = 0.83333375

STEP 3: Convert Result to Output's Unit

0.83333375 Meter per Second --> No Conversion Required

FINAL ANSWER

0.83333375 ≈ 0.833334 Meter per Second <-- Cut Velocity

Cutting Velocity for given Taylor's Tool Life

Go Cut Velocity = Taylors Intercept or Taylor's Constant/((Tool Life in Cutting Velocity^Taylors Tool Life Exponent in Cutting Velocity)*(Feed Rate in Cutting Velocity^Taylors Exponent For Feed Rate in Cutting Velocity)*(Cut Depth^Taylor's Exponent in Cutting Velocity))

Taylor's Exponent given Cutting Velocities, Tool Lives for two Machining Conditions

Go Taylors Tool Life Exponent in Cutting Velocity = (-1)*ln(Cut Velocity/Reference Cutting Velocity in Cutting Velocity)/ln(Tool Life in Cutting Velocity/Reference Tool Life in Cutting Velocity)

Reference Cutting Velocity given Tool Lives, Cutting Velocity under Machining Condition

Go Reference Cutting Velocity in Cutting Velocity = Cut Velocity/((Reference Tool Life in Cutting Velocity/Tool Life in Cutting Velocity)^Taylors Tool Life Exponent in Cutting Velocity)

Cutting Velocity given Tool Lives and Cutting Velocity for Reference Machining Condition

Go Cut Velocity = Reference Cutting Velocity in Cutting Velocity*(Reference Tool Life in Cutting Velocity/Tool Life in Cutting Velocity)^Taylors Tool Life Exponent in Cutting Velocity

Taylor's Intercept given Cutting Velocity and Taylor's Tool Life

Go Taylors Intercept or Taylor's Constant = Taylor Cutting Velocity*(Tool Life in Cutting Velocity^Taylors Tool Life Exponent in Cutting Velocity)

Cutting Velocity using Taylor's Tool Life and Intercept

Go Taylor Cutting Velocity = Taylors Intercept or Taylor's Constant/(Tool Life in Cutting Velocity^Taylors Tool Life Exponent in Cutting Velocity)

Cutting Velocity for given Tool Life and Volume of Metal Removed

Go Cut Velocity = Volume of Metal Removed/(Tool Life in Cutting Velocity*Feed Rate in Cutting Velocity*Cut Depth)

Resultant Cutting Velocity

Go Resultant Cutting Velocity = Cutting Velocity/cos((Cutting Speed Angle))

Cutting Speed of Free-Cutting Steel given Cutting Velocity of Tool and Machinability Index

Go Cutting Speed of Free-Cutting Steel = Cut Velocity*100/Machinability Index of A Material

Cutting Velocity using Machinability Index

Go Cut Velocity = Machinability Index of A Material*Cutting Speed of Free-Cutting Steel/100

Machinability Index

Go Machinability Index of A Material = Cut Velocity*100/Cutting Speed of Free-Cutting Steel

Feed for Sintered-Carbide Tools using Crater Depth

Go Feed Rate in Cutting Velocity = (Tool Wear Crater Depth-0.06)/0.3

Crater Depth for Sintered-Carbide Tools

Go Tool Wear Crater Depth = 0.06+0.3*Feed Rate in Cutting Velocity

Cutting Velocity using Machinability Index Formula

Cut Velocity = Machinability Index of A Material*Cutting Speed of Free-Cutting Steel/100
