Tool Changing Time for 1 Tool given Tool Life for Minimum Machining Cost Solution

STEP 0: Pre-Calculation Summary

Formula Used

Time to Change One Tool = (Tool Life*Taylor's Tool Life Exponent/((1-Taylor's Tool Life Exponent)*Time Proportion))-(Cost of a Tool/Machining and Operating Rate)
t_c = (T*n/((1-n)*t_q))-(C/R)
This formula uses 6 Variables

Variables Used

Time to Change One Tool - (Measured in Second) - Time to change one tool refers to the duration required to remove a worn-out or depleted cutting tool from the machine tool's spindle and install a new or reconditioned tool.
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.
Taylor's Tool Life Exponent - Taylor's Tool Life Exponent is an experimental exponent that helps in quantifying the rate of Tool Wear.
Time Proportion - (Measured in Second) - Time Proportion the fractional portion of machining time during which the Cutting Edge of the tool is engaged with the workpiece.
Cost of a Tool - Cost of a tool is a multifaceted consideration that includes the initial purchase price, maintenance costs, tool life, and the impact on overall production costs.
Machining and Operating Rate - Machining and Operating Rate is the money charged for processing on and operating machines per unit time, including overheads.

STEP 1: Convert Input(s) to Base Unit

Tool Life: 3000 Second --> 3000 Second No Conversion Required
Taylor's Tool Life Exponent: 0.125 --> No Conversion Required
Time Proportion: 0.5 Second --> 0.5 Second No Conversion Required
Cost of a Tool: 100 --> No Conversion Required
Machining and Operating Rate: 7 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

t_c = (T*n/((1-n)*t_q))-(C/R) --> (3000*0.125/((1-0.125)*0.5))-(100/7)

Evaluating ... ...

t_c = 842.857142857143

STEP 3: Convert Result to Output's Unit

842.857142857143 Second --> No Conversion Required

FINAL ANSWER

842.857142857143 ≈ 842.8571 Second <-- Time to Change One Tool

< Minimum Machining Cost Calculators

Machining and Operating Rate given Minimum Production Cost

LaTeX Go Machining and Operating Rate = Production Cost of Each Component/(Setup Time+(Constant For Machining Condition*((Tool Life/Reference Tool Life)^Taylor's Tool Life Exponent)/(Reference Cutting Velocity*(1-Taylor's Tool Life Exponent))))

Minimum Production Cost per Component

LaTeX Go Production Cost of Each Component = Machining and Operating Rate*(Setup Time+(Constant For Machining Condition*((Tool Life/Reference Tool Life)^Taylor's Tool Life Exponent)/(Reference Cutting Velocity*(1-Taylor's Tool Life Exponent))))

Non-Productive Time per component given Minimum Production Cost

LaTeX Go Setup Time = Production Cost of Each Component/Machining and Operating Rate-(Constant For Machining Condition*((Tool Life/Reference Tool Life)^Taylor's Tool Life Exponent)/(Reference Cutting Velocity*(1-Taylor's Tool Life Exponent)))

Constant for Machining Operation given Minimum Production Cost

LaTeX Go Constant For Machining Condition = (Production Cost of Each Component/Machining and Operating Rate-Setup Time)*Reference Cutting Velocity*(1-Taylor's Tool Life Exponent)/((Tool Life/Reference Tool Life)^Taylor's Tool Life Exponent)

Tool Changing Time for 1 Tool given Tool Life for Minimum Machining Cost Formula

LaTeX Go

Time to Change One Tool = (Tool Life*Taylor's Tool Life Exponent/((1-Taylor's Tool Life Exponent)*Time Proportion))-(Cost of a Tool/Machining and Operating Rate)
t_c = (T*n/((1-n)*t_q))-(C/R)

Significance of Total Tool Changing Time

The Total Tool Changing Time denotes the time being spent on an important but non-profitable process that is changing the Machining tool. This results in extra cost factors being accounted for as the operators are usually waged per hour or day. It is preferred that the Total Tool Changing Time in a Production Line is low so as there is a low expense on these non-profitable tasks.
