Cutting Velocity using Machinability Index Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

Cutting Velocity - (Measured in Meter per Second) - The Cutting 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: 40 Meter per Minute --> 0.666666666666667 Meter per Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

V = I*V_s/100 --> 125*0.666666666666667/100

Evaluating ... ...

V = 0.833333333333334

STEP 3: Convert Result to Output's Unit

0.833333333333334 Meter per Second -->50 Meter per Minute (Check conversion here)

FINAL ANSWER

50 Meter per Minute <-- Cutting Velocity

(Calculation completed in 00.004 seconds)

Cutting Velocity for given Taylor's Tool Life

Go Cutting Velocity = Taylor's Intercept or Taylor's Constant/((Tool Life^Taylor's Tool Life Exponent)*(Feed Rate^Taylor's exponent for Feed Rate)*(Depth of Cut^Taylor's exponent for Depth of Cut))

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

Go Taylor's Tool Life Exponent = (-1)*ln(Cutting Velocity/Reference Cutting Velocity)/ln(Tool Life/Reference Tool Life)

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

Go Reference Cutting Velocity = Cutting Velocity/((Reference Tool Life/Tool Life)^Taylor's Tool Life Exponent)

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

Go Cutting Velocity = Reference Cutting Velocity*(Reference Tool Life/Tool Life)^Taylor's Tool Life Exponent

Cutting Velocity for given Tool Life and Volume of Metal Removed

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

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

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

Cutting Velocity using Taylor's Tool Life and Intercept

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

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 = Cutting Velocity*100/Machinability Index of a Material

Cutting Velocity using Machinability Index

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

Machinability Index

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

Feed for Sintered-Carbide Tools using Crater Depth

Go Feed Rate = (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

Cutting Velocity using Machinability Index Formula

Cutting Velocity = Machinability Index of a Material*Cutting Speed of Free-Cutting Steel/100
V = I*V_s/100
