Introduction To Taguchi Method

8-STEPS  IN  TAGUCHI  METHODOLOGY : 

Taguchi method is a scientifically disciplined mechanism for evaluating and implementing improvements in products, processes, materials, equipment, and facilities. These improvements are aimed at improving the desired characteristics and simultaneously reducing the number of defects by studying the key variables controlling the process and optimizing the procedures or design to yield the best results.

The method is applicable over a wide range of engineering fields that include processes that manufacture raw materials, sub systems, products for professional and consumer markets. In fact, the method can be applied to any process be it engineering fabrication, computer-aided-design, banking and service sectors etc. Taguchi method is useful for 'tuning' a given process for 'best' results.

Taguchi proposed a standard 8-step procedure for applying his method for optimizing any process,

8-STEPS  IN  TAGUCHI  METHODOLOGY:

Step-1: IDENTIFY  THE  MAIN  FUNCTION, SIDE  EFFECTS,  AND  FAILURE  MODE

Step-2: IDENTIFY  THE  NOISE  FACTORS, TESTING  CONDITIONS,  AND  QUALITY  CHARACTERISTICS

Step-3: IDENTIFY  THE  OBJECTIVE  FUNCTION  TO  BE  OPTIMIZED

Step-4: IDENTIFY  THE  CONTROL  FACTORS  AND  THEIR  LEVELS

Step-5: SELECT  THE  ORTHOGONAL  ARRAY  MATRIX  EXPERIMENT

Step-6: CONDUCT  THE  MATRIX  EXPERIMENT

Step-7: ANALYZE  THE  DATA, PREDICT  THE  OPTIMUM  LEVELS  AND  PERFORMANCE

Step-8: PERFORM  THE  VERIFICATION  EXPERIMENT AND  PLAN  THE  FUTURE  ACTION
