Variables Used
Taylor's Tool Life Exponent - Taylor's Tool Life Exponent is an experimental exponent that helps in quantifying the rate of Tool Wear.
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).
Reference Cutting Velocity - (Measured in Meter per Second) - Reference Cutting Velocity is the Cutting Velocity of the tool used in the reference Machining Condition.
Tool Life - (Measured in Second) - Tool Life is the period of time for which the cutting edge, affected by the cutting procedure, retains its cutting capacity between sharpening operations.
Reference Tool Life - (Measured in Second) - Reference Tool Life is the Tool Life of the tool obtained in the reference Machining Condition.
STEP 1: Convert Input(s) to Base Unit
Cutting Velocity: 10 Meter per Second --> 10 Meter per Second No Conversion Required
Reference Cutting Velocity: 5 Meter per Minute --> 0.0833333333333333 Meter per Second (Check conversion here)
Tool Life: 75 Minute --> 4500 Second (Check conversion here)
Reference Tool Life: 1200 Minute --> 72000 Second (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
n = (-1)*ln(V/Vref)/ln(T/Tref) --> (-1)*ln(10/0.0833333333333333)/ln(4500/72000)
Evaluating ... ...
