Question 1

Gauge R&R is used to determine the consistency and thickness of materials.

Accepted Answer

Gauge R&R (Repeatability and Reproducibility) is a statistical tool used to evaluate the amount of variation in a measurement system arising from the measurement device and the operator, not specifically for determining consistency and thickness of materials.

Question 2

The Pitman arm on a car costs $105 to repair. Compute the quality loss function for losses incurred as a result of deviation from a target where a tolerance of 10 mm plus or minus 0.15 mm is required and the mean squared deviation from the target is (0.16)².

Accepted Answer

The quality loss function L = k * (mean squared deviation), where k = cost / tolerance^2. Here, k = 105 / (0.15)^2 = 4666.67. Thus, L = 4666.67 * (0.16)^2 = 119.04, approximately 119.

Question 14

What is the Taguchi constant for a device that costs $500 to repair and a tolerance of plus or minus 2 mm with a mean squared deviation from the target of 3?

Accepted Answer

The Taguchi loss function is calculated as L = k * (y - T)^2, where L is the loss, k is the Taguchi constant, y is the actual value, and T is the target value. The constant k can be found using k = cost / (tolerance)^2. Here, k = 500 / (2^2) = 500 / 4 = 125.

Question 15

The process of developing specification limits is known as ________.

Accepted Answer

Tolerance design is the process of developing specification limits to ensure that products meet quality standards and function as intended.
