Total Tool Changing Time using Average Production Cost Solution

STEP 0: Pre-Calculation Summary
Formula Used
Total Tool Changing Time = (Batch Size*(Production Cost of Each Component-Cost of A Tool*(Setup Time+Machining Time))-Number of Tools Used*Cost of A Tool)/(Cost of A Tool)
TTCT = (Nb*(Cpr-Ct*(ts+tm))-Nt*Ct)/(Ct)
This formula uses 7 Variables
Variables Used
Total Tool Changing Time - (Measured in Second) - Total Tool Changing Time is the average time required by the operator or automation system to change the tool.
Batch Size - Batch Size is the count of similar kinds of products to be manufactured.
Production Cost of Each Component - Production Cost of Each Component is the total amount that it takes to produce a single component from scratch.
Cost of A Tool - The Cost of a Tool is simply the cost of one tool being used for machining.
Setup Time - (Measured in Second) - Setup Time of each component is the time required to load/unload the workpiece and position the tool for production for one component.
Machining Time - (Measured in Second) - Machining Time is the time when a machine is actually processing something. Generally, machining time is the term used when there is a removal of unwanted material.
Number of Tools Used - The Number of Tools Used is the total number of tools used for manufacturing a batch of products.
STEP 1: Convert Input(s) to Base Unit
Batch Size: 2 --> No Conversion Required
Production Cost of Each Component: 15000 --> No Conversion Required
Cost of A Tool: 80 --> No Conversion Required
Setup Time: 0.9 Minute --> 54 Second (Check conversion here)
Machining Time: 1.15 Minute --> 69 Second (Check conversion here)
Number of Tools Used: 3 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
TTCT = (Nb*(Cpr-Ct*(ts+tm))-Nt*Ct)/(Ct) --> (2*(15000-80*(54+69))-3*80)/(80)
Evaluating ... ...
TTCT = 126
STEP 3: Convert Result to Output's Unit
126 Second -->2.1 Minute (Check conversion here)
FINAL ANSWER
2.1 Minute <-- Total Tool Changing Time
(Calculation completed in 00.004 seconds)

3 Tool Changing Time Calculators

Tool Changing Time for Each Tool given Average Production Cost
Go Time to Change One Tool = (Batch Size*(Production Cost of Each Component-Cost of A Tool*(Setup Time+Machining Time))-Number of Tools Used*Cost of A Tool)/(Cost of A Tool*Number of Tools Used)
Total Tool Changing Time using Average Production Cost
Go Total Tool Changing Time = (Batch Size*(Production Cost of Each Component-Cost of A Tool*(Setup Time+Machining Time))-Number of Tools Used*Cost of A Tool)/(Cost of A Tool)
Total Tool Changing Time given Total Production Cost
Go Total Tool Changing Time = (Total Production Cost-(Total Cost of Tools Used+Total Machining And Operating Cost+Total Non-Productive Cost))/(Number of Tools Used*Cost of A Tool)

Total Tool Changing Time using Average Production Cost Formula

Total Tool Changing Time = (Batch Size*(Production Cost of Each Component-Cost of A Tool*(Setup Time+Machining Time))-Number of Tools Used*Cost of A Tool)/(Cost of A Tool)
TTCT = (Nb*(Cpr-Ct*(ts+tm))-Nt*Ct)/(Ct)

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.

How to Calculate Total Tool Changing Time using Average Production Cost?

Total Tool Changing Time using Average Production Cost calculator uses Total Tool Changing Time = (Batch Size*(Production Cost of Each Component-Cost of A Tool*(Setup Time+Machining Time))-Number of Tools Used*Cost of A Tool)/(Cost of A Tool) to calculate the Total Tool Changing Time, The Total Tool Changing Time using Average Production Cost is a method to determine the maximum time that can be spared to be spent for changing the tool. Total Tool Changing Time is denoted by TTCT symbol.

How to calculate Total Tool Changing Time using Average Production Cost using this online calculator? To use this online calculator for Total Tool Changing Time using Average Production Cost, enter Batch Size (Nb), Production Cost of Each Component (Cpr), Cost of A Tool (Ct), Setup Time (ts), Machining Time (tm) & Number of Tools Used (Nt) and hit the calculate button.
