4.6 Robust Design
The loss function
loss varies with the square of the deviation of the quality characteristics from the target value L(Y) = k(Y-M)^2
Taguchi methodology based on precept that...
lowest cost to society represents product with highest quality which is achieved by reducing variation in product characteristics
Robust design creates
performance characteristics that are insensitive to variations in the manufacturing process
Taguchi tolerance design
performance characteristics that are insensitive to variations in the manufacturing process design of product/process that results in functionally acceptable products with economic tolerances improves product quality by reducing the effects of variability
Robust is the design of a...
product or process that results in functionally acceptable products with economic tolerances
Robust design improves
product quality by reducing the effects of variability
Issues with Taguchi's method
quality loss function not related to any physical relationship between a critical parameter and any quality aspect difficult to determine l
