This document provides an overview of a project that aims to compare the effectiveness of the Taguchi method and Shainin design of experiments (DOE) technique for optimizing surface roughness. The objectives are to compare the two methods and determine the applicability of the Taguchi method. The problem statement indicates the adoption of experimental design techniques can help a company improve cost and quality. The literature review discusses perspectives on the relative power and validity of different approaches. The methodology section indicates Taguchi and Shainin DOE approaches will be followed. The expected result is to identify optimum parameters for surface roughness measurement using the techniques and compare their effectiveness.

3. ABSTRACT
 The experimental study presented in this paper aims to highlight the
application of Taguchi and Shainin DOE
 It also to compare the effectiveness of Taguchi and Shainin DOE
experimental design processes as applied to surface roughness

4. PROJECT BACKGROUND
 Statistical quality improvement methods such as Taguchi and DOE
techniques form an essential part of the search for improved
product performance.
 The Taguchi method has been widely used in engineering analysis
and is a powerful tools to design a quality system.
 Design of experiments (DOE) or experimental design is the design of
any information-gathering exercises where variation is present,
whether under the full control of the experimenter or not.

5. OBJECTIVES
To compare effectiveness Taguchi method and Shainin
DOE experimental design processes in surface roughness.
To determine applicability Taguchi method in optimizing
accuracy of surface roughness.

6. PROBLEM STATEMENT
The adoption of the experimental design techniques
outlined in this paper and their application to a real
engineering problem will enable a company to apply the
techniques and to attain improvements in terms of cost
and quality.

Experimental Design for Quality Improvement. Quality and Reliability

“Classical DOE and Taguchi approaches are still much more powerful,
more statistically valid and more robust. Shainin methods could
perhaps have some applicability in medium-to-high volume
processes for which a high level of quality has already been
achieved. They can also be used when dealing with binary response
(for example, a machine work or not) and the reason behind the
response may be due to a huge amount of variables”

“The Taguchi approach provides for a powerful product/process
enhancement capability where system robustness can be created
through the identification of a wider range of influential variables that
can affect system output. The Taguchi techniques provides its strength
through being able to accurately identify main effects and
interactions through partial factorial experimentation”
