This formula uses 7 Variables
Variables Used
Batch Size - Batch Size is the count of similar kinds of products to be manufactured.
Number of Tools Used - The Number of Tools Used is the total number of tools used for manufacturing a batch of products.
Reference Tool Life - (Measured in Second) - Reference Tool Life is the Tool Life of the tool obtained in the reference Machining Condition.
Reference Cutting Velocity - (Measured in Meter per Second) - Reference Cutting Velocity is the Cutting Velocity of the tool used in the reference Machining Condition.
Cutting Velocity - (Measured in Meter per Second) - The Cutting Velocity is the tangential velocity at the periphery of the cutter or workpiece (whichever is rotating).
Taylor's Tool Life Exponent - Taylor's Tool Life Exponent is an experimental exponent that helps in quantifying the rate of Tool Wear.
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.
STEP 1: Convert Input(s) to Base Unit
Number of Tools Used: 3 --> No Conversion Required
Reference Tool Life: 1200 Minute --> 72000 Second (Check conversion here)
Reference Cutting Velocity: 5 Meter per Minute --> 0.0833333333333333 Meter per Second (Check conversion here)
Cutting Velocity: 550 Meter per Minute --> 9.16666666666667 Meter per Second (Check conversion here)
Taylor's Tool Life Exponent: 0.55 --> No Conversion Required
Machining Time: 0.5 Minute --> 30 Second (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Nb = Nt*(Tref*((Vref/V)^(1/n)))/tm --> 3*(72000*((0.0833333333333333/9.16666666666667)^(1/0.55)))/30
Evaluating ... ...
Nb = 1.39865123293204
STEP 3: Convert Result to Output's Unit
1.39865123293204 --> No Conversion Required
FINAL ANSWER
1.39865123293204 1.398651 <-- Batch Size

What is Batch Size? What is an Ideal Batch Size?

Batch size is the number of units manufactured in a production run at a time. A batch in production usually comprises identical or at least similar products. An Ideal Batch Size is the one that can cover up the total production cost of the batch including setup and overhead costs and can yield more profit to the firm.
