Answer:
A) 1.111
B) 0.889
Explanation:
given data :
outer diameter of connecting rods = 1 ± 0.01 inch
sample mean outer diameter = 1.002 inches
standard deviation = 0.003 inches
A) Calculating the Cp of the process
mean = 1.002
Standard deviation = 0.003
LSL = 1 - 0.01 = 0.99
USL = 1 + 0.01 = 1.01
=
= 1.111
B) calculate Cpk
mean = 1.002, LSL = 0.99, USL = 1.01 , deviation = 0.003
= min [(0.012/0.009) , (0.008/0.009) ]
= min [ 1.333, 0.889 ]
hence Cpk = 0.889
