Average Cutting Edges per insert given Tool Changing Time Solution

STEP 0: Pre-Calculation Summary
Formula Used
Average Number of Cutting Edges used per Insert = (Time to Replace Index-Time to Insert Index)/(Time to Change One Tool-Time to Insert Index)
CEavg = (tr-ti)/(tc-ti)
This formula uses 4 Variables
Variables Used
Average Number of Cutting Edges used per Insert - Average Number of Cutting Edges used per Insert is the supposed count of cutting edges that engaged during insertion into the holder.
Time to Replace Index - (Measured in Second) - Time to Replace Index is the time required to replace the index itself.
Time to Insert Index - (Measured in Second) - Time to Insert Index is the time required to insert the tool in an index.
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.
STEP 1: Convert Input(s) to Base Unit
Time to Replace Index: 9 Minute --> 540 Second (Check conversion here)
Time to Insert Index: 4.45 Minute --> 267 Second (Check conversion here)
Time to Change One Tool: 5 Minute --> 300 Second (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
CEavg = (tr-ti)/(tc-ti) --> (540-267)/(300-267)
Evaluating ... ...
CEavg = 8.27272727272727
STEP 3: Convert Result to Output's Unit
8.27272727272727 --> No Conversion Required
FINAL ANSWER
8.27272727272727 8.272727 <-- Average Number of Cutting Edges used per Insert
(Calculation completed in 00.004 seconds)

Estimated Tool Changing Time for Disposable-Insert Tool
Go Time to Change One Tool = (Time to Insert Index*(Average Number of Cutting Edges used per Insert-1)+Time to Replace Index)/Average Number of Cutting Edges used per Insert
Time to Replace Insert given Tool Changing Time for Disposable-Insert Tool
Go Time to Replace Index = Time to Change One Tool*Average Number of Cutting Edges used per Insert-Time to Insert Index*(Average Number of Cutting Edges used per Insert-1)
Depreciation Rate of Machine Tool given Machining and Operating Rate
Go Depreciation Rate = (Machining and Operating Rate-(Wage Rate*(100+Operator's Overhead Percentage)/100))*100/(100+Machine Overhead Percentage)
Operator's Overhead Percentage given Machining and Operating Rate
Go Operator's Overhead Percentage = ((Machining and Operating Rate-(Depreciation Rate*(100+Machine Overhead Percentage)/100))*100/Wage Rate)-100
Machine Overhead Percentage given Machining and Operating Rate
Go Machine Overhead Percentage = ((Machining and Operating Rate-(Wage Rate*(100+Operator's Overhead Percentage)/100))*100/Depreciation Rate)-100
Average Cutting Edges per insert given Tool Changing Time
Go Average Number of Cutting Edges used per Insert = (Time to Replace Index-Time to Insert Index)/(Time to Change One Tool-Time to Insert Index)
Operator's Wage Rate given Machining and Operating Rate
Go Wage Rate = (Machining and Operating Rate-(Depreciation Rate*(100+Machine Overhead Percentage)/100))*100/(100+Operator's Overhead Percentage)
Machining and Operating Rate
Go Machining and Operating Rate = (Wage Rate*(100+Operator's Overhead Percentage)/100)+(Depreciation Rate*(100+Machine Overhead Percentage)/100)
Cutting Edges used during Life of Holder given Estimated Tool Costs
Go Cutting Edges used during Life of Holder = Cost of the Holder/(Tool Cost-(Cost of Insert/Average Number of Cutting Edges used per Insert))
Average Cutting Edges used per insert given Estimated Tool Costs
Go Average Number of Cutting Edges used per Insert = Cost of Insert/(Tool Cost-(Cost of the Holder/Cutting Edges used during Life of Holder))
Working Hours per year given Depreciation Rate
Go Number of Working Hours per Year = Initial Cost of the Machine/(Amortization Period*Depreciation Rate)
Amortization given Depreciation Rate
Go Amortization Period = Initial Cost of the Machine/(Number of Working Hours per Year*Depreciation Rate)
Depreciation Rate of Machine Tool
Go Depreciation Rate = Initial Cost of the Machine/(Number of Working Hours per Year*Amortization Period)
Average Number of Regrinds Possible, given Estimated Tool Costs
Go Average Number of Regrinds Possible = Cost of a Tool/(Tool Cost-Cost of Grinding)

Average Cutting Edges per insert given Tool Changing Time Formula

Average Number of Cutting Edges used per Insert = (Time to Replace Index-Time to Insert Index)/(Time to Change One Tool-Time to Insert Index)
CEavg = (tr-ti)/(tc-ti)

Tool-Changing Time

The Total Tool-Changing Time comprises the time required to remove the tool from the machine, place a new tool in the machine, set the new tool in its correct position, and restart the machining process.
