Average Number of Regrinds Possible, given Estimated Tool Costs Solution

STEP 0: Pre-Calculation Summary
Formula Used
Average Number of Regrinds Possible = Cost of a Tool/(Tool Cost-Cost of Grinding)
Ng = Ct/(TC-Cg)
This formula uses 4 Variables
Variables Used
Average Number of Regrinds Possible - Average Number of Regrinds Possible is the number of times a Tool is supposed to be grindable to give a sharp edge.
Cost of a Tool - The Cost of a Tool is simply the cost of one tool being used for machining.
Tool Cost - Tool Cost is the amount of money spend on the purchase, maintenance and changing of tools.
Cost of Grinding - Cost of Grinding is the amount spent on grinding of a given tool.
STEP 1: Convert Input(s) to Base Unit
Cost of a Tool: 80 --> No Conversion Required
Tool Cost: 200 --> No Conversion Required
Cost of Grinding: 180 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Ng = Ct/(TC-Cg) --> 80/(200-180)
Evaluating ... ...
Ng = 4
STEP 3: Convert Result to Output's Unit
4 --> No Conversion Required
FINAL ANSWER
4 <-- Average Number of Regrinds Possible
(Calculation completed in 00.004 seconds)

15 Estimation for Optimal Conditions Calculators

Time to Index Insert given Tool Changing Time for Disposable-Insert Tool
Go Time to Insert Index = (Time to Change One Tool*Average Number of Cutting Edges used per Insert-Time to Replace Index)/(Average Number of Cutting Edges used per Insert-1)
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 Number of Regrinds Possible, given Estimated Tool Costs Formula

Average Number of Regrinds Possible = Cost of a Tool/(Tool Cost-Cost of Grinding)
Ng = Ct/(TC-Cg)

Ideal Capacity of a Machine Tool

The desired characteristics of a Machine Toole are:
1. Powerful and high Strength
2. Rigid and Stable
3. Tools allows much higher Cutting Velocity, if required and permissible
4. Low wear
