Question

The specifications for a manifold gasket that installs between two engine parts calls for a thickness of 2.500 mm t.020 mm. The standard deviation of the process is estimated to be 0.004 mm. 28. What are the upper and lower specification limits for this product? A) LSL 2.492 mm, USL 2.508 mm B LSL= 2.408 mm, USL 2.502 mm C) LSL 2.480 mm, USL-2.520 mm D) LSL 2.488 mm, USL -2.512 mm E) LSL- 2.496 mm, USL 2.504 mm 29. The process is currently operating at a mean thickness of 2.50 mm. What is the Cp for this process? A. 3.910 B. 1.000 C. 0.667 D. 0.333 E. 1.667 30. If the process mean were to drift from its setting of 2.500 mm to a new mean of 2.497. What is the Cpk for this process? A. 1.917 B. 0.417 C.0.75 D. 1.417 E. 0.083
