Variables Used

Time Proportion of Cutting Edge For Minimum Cost - Time Proportion of Cutting Edge For Minimum Cost is the minimum fractional portion of machining time during which the Cutting Edge of the tool is engaged with the workpiece.
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.
Taylor's Tool Life Exponent - Taylor's Tool Life Exponent is an experimental exponent that helps in quantifying the rate of Tool Wear.
Time to Change One Tool - (Measured in Second) - Time to Change One Tool is the measure of time it takes to change one tool during machining.
Cost of A Tool - Cost of A Tool is simply the cost of one tool being used for machining.
Machining And Operating Rate - Machining And Operating Rate is the money charged for processing on and operating machines per unit time, including overheads.

STEP 1: Convert Input(s) to Base Unit

Tool Life: 4500 Second --> 4500 Second No Conversion Required
Taylor's Tool Life Exponent: 0.032362 --> No Conversion Required
Time to Change One Tool: 75 Second --> 75 Second No Conversion Required
Cost of A Tool: 478575 --> No Conversion Required
Machining And Operating Rate: 101 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_min = T*n/((1-n)*(t_c+(C_t/M))) --> 4500*0.032362/((1-0.032362)*(75+(478575/101)))

Evaluating ... ...

Q_min = 0.0312669872012381

STEP 3: Convert Result to Output's Unit

0.0312669872012381 --> No Conversion Required

FINAL ANSWER

0.0312669872012381 ≈ 0.031267 <-- Time Proportion of Cutting Edge For Minimum Cost

Advantages of Constant-Cutting-Speed Operation

Constant Surface Speed provides at least four advantages:
1. It simplifies programming.
2. It provides a consistent workpiece finish.
3. It optimizes Tool Life - Tools will always machine at the appropriate speed.
4. It optimizes Machining Time - Cutting conditions will always be properly set, which translates to minimal machining time.
