"Quality Improvement of Medical Wire Manufacturing Process," Quality Improvement, Vol. 25, pp. 151-163 Description: Fractional factorial experiment relating 4 factors to Yield Strength/Ultimate Tensile Strength (%) in Medical Wire. Run in 3 Blocks with 5 replicate measurements per wire spool. Factors: Drawing Machine, Die Reduction Angle, Die Bearing Length, Supply Diameter. Each factor at 2 levels. Experiment run as 2^(4-1) in each block, with I=ABCD Variables/Columns Spool ID 7-8 Block 16 Factor A Level 24 /* 0=Low, 1=High */ Factor B Level 32 /* 0=Low, 1=High */ Factor C Level 40 /* 0=Low, 1=High */ Factor D Level 48 /* 0=Low, 1=High */ YS/UTS (percent) 50-56
