In a tolerance design process,a _____ is needed to account for engineering uncertainty regarding the maximum variation allowable and compatibility with satisfactory product performance.
A)process variation limit
B)covariance factor
C)factor of safety
D)capacity variance

Question

Quizplus · Accepted Answer

A factor of safety is necessary in a tolerance design process to account for any uncertainties that arise due to variations in the manufacturing process or materials. This factor provides a cushion to ensure that the final product will meet performance requirements even in the presence of these uncertainties. A covariance factor is used to take into account the correlation between two variables, and is not directly related to tolerance design. A process variation limit and capacity variance are not directly related to accounting for engineering uncertainty in a tolerance design process.
