Utilização do método DMAIC para análise do comportamento do coeficiente de atrito em filmes flexíveis

Abstract

The Lean Six Sigma philosophy aims to increase productivity, eliminate waste, reduce costs and process variability through control tools. Ensuring product quality makes the production process more efficient and economical, in addition to improving customer relationships by providing products with fewer defects, aiming to achieve the goal of zero defects. The DMAIC cycle is a Lean methodology that consists of 5 steps, with the objective of defining, measuring, analyzing, improving and controlling the process, through the use of tools such as CTQ, Project Charter, 5W2H, SIPOC, Brainstorming, Ishikawa Diagram, 5 Whys, Hypothesis Testing, DOE, Control Chart, Training and Auditing. By applying the methodology to investigate the root cause of a technical divergence in the coefficient of friction of flexible polymeric packaging, it was possible to solve the problem, in addition to improving the process through continuous improvement plans, which can be practiced in other stages of production.
