Case Study
•Mr John wants to determine the optimum setting for the wire diameter and winding tension.
•His goal is to achieve the target values of the two main responses, coil resistance and coil mass.
•Given spec are
–coil resistance, max spec is 5.985 ohm ,min spec is 5.415 ohm and target value is 5.80 ohm
–Coil mass, max spec is 0.4692 g , min spec is 0.4508 g and target value is 0.4650 g

How to optimize the setting for both inputs (wire diamtere and winding tension) in order to achieve the target values of responses?
Guideline (using Minitab):
•Stat>DOE>Factorial>Create Factorial Design
–2 factors, 2 levels
–Enter the data for both responses (Coil res & Coil mass)
•Stat>DOE>Factorial>Analyze Factorial Design
•Stat>DOE>Factorial>Response Optimizer
–Click Setup.
–Goal for both responses should be “target”.
