Tool Life for Minimum Production Cost when High-Speed Steel Tool is used Solution

STEP 0: Pre-Calculation Summary
Formula Used
Tool Life = 7*(Time to Change One Tool+(Cost of a Tool/Cost of a Tool))
T = 7*(tc+(Ct/Ct))
This formula uses 3 Variables
Variables Used
Tool Life - (Measured in Second) - Tool Life is the period of time for which the cutting edge, affected by the cutting procedure, retains its cutting capacity between sharpening operations.
Time to Change One Tool - (Measured in Second) - Time to Change One Tool is the measure of time it takes to change one tool during machining.
Cost of a Tool - The Cost of a Tool is simply the cost of one tool being used for machining.
STEP 1: Convert Input(s) to Base Unit
Time to Change One Tool: 1.5 Minute --> 90 Second (Check conversion here)
Cost of a Tool: 100 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
T = 7*(tc+(Ct/Ct)) --> 7*(90+(100/100))
Evaluating ... ...
T = 637
STEP 3: Convert Result to Output's Unit
637 Second -->10.6166666666667 Minute (Check conversion here)
FINAL ANSWER
10.6166666666667 10.61667 Minute <-- Tool Life
(Calculation completed in 00.004 seconds)

10+ Tool Life for Minimum Production Cost Calculators

Machining and Operating Rate if cost of changing tool is also considered
Go Machining and Operating Rate = ((Cost of a Tool+Cost of changing each Tool)/Time to Change One Tool)*((1-Taylor's Tool Life Exponent)/(2*Taylor's Tool Life Exponent-1))
Tool Life for Minimum Production Cost given Tool Changing Cost
Go Tool Life = (1-Taylor's Tool Life Exponent)*(Cost of changing each Tool+Cost of a Tool)/(Taylor's Tool Life Exponent*Cost of a Tool)
Cost to change One Tool given Tool Life
Go Cost of changing each Tool = Cost of a Tool*(Tool Life*Taylor's Tool Life Exponent/(1-Taylor's Tool Life Exponent))-Cost of a Tool
Tool Changing Time for each Tool given Tool Life and tool cost
Go Time to Change One Tool = (Tool Life*Taylor's Tool Life Exponent/(1-Taylor's Tool Life Exponent))-(Cost of a Tool/Cost of a Tool)
Tool Life for Minimum Production Cost
Go Tool Life = (1-Taylor's Tool Life Exponent)*(Time to Change One Tool+(Cost of a Tool/Cost of a Tool))/Taylor's Tool Life Exponent
Machining and Operating Rate using Min Production Cost and Min Production time
Go Machining and Operating Rate = (Cost of a Tool/Time to Change One Tool)*((1-Taylor's Tool Life Exponent)/(2*Taylor's Tool Life Exponent-1))
Cost of One Tool for Minimum Production Cost given Tool Changing Cost
Go Cost of a Tool = Machining and Operating Rate*Time to Change One Tool*((2*Taylor's Tool Life Exponent-1)/(1-Taylor's Tool Life Exponent))
Cost of One Tool given Tool Life
Go Cost of a Tool = Machining and Operating Rate*Time to Change One Tool*((2*Taylor's Tool Life Exponent-1)/(1-Taylor's Tool Life Exponent))
Tool Life for Minimum Production Cost when High-Speed Steel Tool is used
Go Tool Life = 7*(Time to Change One Tool+(Cost of a Tool/Cost of a Tool))
Tool Life for Minimum Production Cost when Carbide Tool is used
Go Tool Life = 3*(Time to Change One Tool+(Cost of a Tool/Cost of a Tool))

Tool Life for Minimum Production Cost when High-Speed Steel Tool is used Formula

Tool Life = 7*(Time to Change One Tool+(Cost of a Tool/Cost of a Tool))
T = 7*(tc+(Ct/Ct))

Taylor's Tool Life Equation

This relationship is credited to F. W. Taylor (~1900). It gives the relation between cutting speed and tool life. VTn = C where V= Cutting Velocity, T= Tool Life, n and C are Taylor's Constant.
The Taylor's Tool Life Exponent for High-Speed Steel Tool is approximately 0.125
