Automatic drilling improvement and standardization by design-of-experiments (DOE)

Abstract

Na manufactura aeroespacial,para um dado intervalo de tempo imposto,os requisitos de qualidade têm de ser cumpridos.O custo operacional tem um pesado impacto,especial mente em operações repetidas,como a operação de furação decompósitos na indústria aeroespacial.É realizado um estudo da furação em compósitos,em particular dos bordos de ataque dos Estabilizadores dos jatos executivos Embraer Legacy 450/500 e Praetor 500/600. Este estudo consiste na análise do desempenho das máquinas pneumáticas e introdução de máquinas semi-automáticas com parâmetros programáveis.Os dados recolhidos nas operações de furação com diferentes parâmetros e aplicação do conceito de Planeamento de Ensaios(hiper cubos Latinos)para uma análise eficiente,visam in crementar o conhecimento sobre a furação,e de terminar os parâmetros mais adequados para cada geometria de ferramenta.Neste contexto,aumentou-se a vida útil da broca; ABSTRAT: In aerospace manufacturing, for a given imposed time interval, quality requirements must be met. Operating costs have a significant impact, especially on repeated operations, such as the drilling of composites in the aerospace industry. A composite drilling study is carried out, in particular the leading edges of the Embraer Legacy 450/500 and Praetor 500/600 Executive Jet Stabilizers. This study is accomplished by a performance analysis of pneumatic machines and the introduction of semi-automatic machines with programmable parameters. The data collected in drilling operations with different parameters and the application of the concept of Design of Experiments (specifically Latin hypercubes) for an efficient analysis, aim to increase the knowledge about drilling, and to determine the most appropriate parameters for each tool geometry. In this context, the operational life of the drill was increased
