The surface quality is dependent on certain cutting process parameters that can vary, causing variations on the surface roughness. The main subject of this paper focuses on the experimental research management applied to a technological process whose final purpose was to determine an equation of the surface roughness depending on the process parameters, obtained by the Al7136 end milling process. The research method used in this paper is the Taguchi’s method. According to the research management steps, in order to perform the experimental determination of the surface roughness, an experimental stand used to determine the objective function was presented. The surface roughness equation was determined using the Minitab 17 software. The regression equation allows to calculate the surface roughness at any point in the established experimental field.

Introduction

Genichi Taguchi has developed a method that bears his name, in order to improve the quality of the manufactured products, with applications in engineering, biotechnology, marketing and advertising. The Taguchi method is a method that applies to experimental research, and is often used in processes, products and services modeling and optimizing in certain situations.
