Average Cutting Edges used per insert given Estimated Tool Costs Solution

STEP 0: Pre-Calculation Summary
Formula Used
Average Number of Cutting Edges used per Insert = Cost of Insert/(Tool Cost-(Cost of the Holder/Cutting Edges used during Life of Holder))
CEavg = Ci/(TC-(Ch/CEhl))
This formula uses 5 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.
Cost of Insert - Cost of Insert is the amount spent on inserting a tool in its specified holder.
Tool Cost - Tool Cost is the amount of money spend on the purchase, maintenance and changing of tools.
Cost of the Holder - Cost of the Holder is the amount required to get a new holder for a tool.
Cutting Edges used during Life of Holder - Cutting Edges used during Life of Holder is the total number of Cutting Edges engaged with the holder until it wears off beyond use.
STEP 1: Convert Input(s) to Base Unit
Cost of Insert: 900 --> No Conversion Required
Tool Cost: 200 --> No Conversion Required
Cost of the Holder: 2000 --> No Conversion Required
Cutting Edges used during Life of Holder: 110 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
CEavg = Ci/(TC-(Ch/CEhl)) --> 900/(200-(2000/110))
Evaluating ... ...
CEavg = 4.95
STEP 3: Convert Result to Output's Unit
4.95 --> No Conversion Required
FINAL ANSWER
4.95 <-- Average Number of Cutting Edges used per Insert
(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 Cutting Edges used per insert given Estimated Tool Costs Formula

Average Number of Cutting Edges used per Insert = Cost of Insert/(Tool Cost-(Cost of the Holder/Cutting Edges used during Life of Holder))
CEavg = Ci/(TC-(Ch/CEhl))

The Importance of Tool Holders

A tool holder is very important in mechanized processes that require high levels of accuracy because they are the interface between a tool and a machine. An imbalance between a high-speed tool and a machine could damage the final product by providing an undesired finish, or it could shorten the lifespan of a machine by wearing down the spindle. The right tool holder, when properly installed and cared for, makes sure cutting processes are performed accurately and safely.
