Aplicação da técnica de delineamento de experimentos para criação de um padrão para avaliação da vida útil de pastilhas de corte utilizadas em processos de usinagem

Abstract

The present project had as objective define an internal performance standard for machining inserts (cutting tools) with specific test parameters and minimum acceptance criteria for suppliers. The evaluation was performed in turning machining operations using different cutting speeds. Critical factors of direct influence on the inserts lifetime, such as quantity consumed, volume of machined parts and manufacturing costs were considered. It was evaluated in a practical way through the design of experiment technique using as a single factor the cutting speed. In this way, the project allowed the development of internal performance standards for machining metal insert, defining specific test parameters among different manufacturers, establishing minimum acceptance criteria.
