Projeto, manufatura e validação de um sistema de medição de altura por perfilômetro a laser

Abstract

This work carries out the design of a system for measuring the relative height of a component using methods of problem solving. Initially, the analysis of a system for measuring height by camera with the aid of the Ishikawa Diagram was performed to identify the root causes of approval of parts outside the tolerance range. Then a CAD (Computer Aided Design) model of the new system was created, which uses a laser profiler to solve the vulnerabilities of the other method and contains parts designed to be produced by additive manufacturing of extrusion of thermoplastic material. Needed parts are manufactured, the new system assembled and than subjected to statistical analysis of process quality and means of measurement using the SixSigma methodology. Scatter, frequency and amplitude graphs were obtained with results of Cg, Cgk and %GRR being better than expected, validating the process and the system as capable.
