The Taguchi Philosophy Is a New Point of View In Thestatistical Decision Instead of Classical Dichotomic Type of Decision Good/Bad,With the Principal Goal of Improving Quality of Products In the Industrialpractice. In the Present Paper Are Introduced some New Adaptive Models Oftaguchi’S Loss Functions Using Statistical Software. We Propose Quality Losslaws, Which Are Symmetrical and Asymmetrical Distributions, and Therefore Moreadequate Models, Which Give a Better Approximation In the Real World. This Paper Presents a New Approach to Determiningeconomical Values For Manufacturer Lower and Upper Specification Limits Using Anewly Derived Hybrid Function For Expected Cost. the Identification and Use Ofspecification Limits Are Essential In Protecting the Producer from Shippingdefective Products That Pass Unnoticed Due to Measurement Error. This Costfunction Is Composed of Four Parts: a Generic Taguchi Loss Function, a Functionfor Rework Cost, a Function For Scrap Cost, and a Function That Describes Avariance to Cost Tradeoff. the Expected Cost Function Does Not Assume Theprocess Mean to Be Equal to the Target Value of the Process Nor Is Itrestricted to Being Symmetrical. the Cost Function Is Implemented Amongdifferent Production Systems and Optimal Values of Manufacturer Lower and Upperspecification Limits Are Determined For Each System. In This Study, the Taguchi Method Is Utilized to Discoverthe Optimal Cutting Parameters In Turning Operations. the Orthogonal Array, Thesignal-T ...
