Abstract in Portuguese
O objetivo deste trabalho é apresentar uma solução funcional de um mecanismo de corte de cerâmicas por abrasão, para possibilitar a construção de transdutores piezocompósitos de ultra-som através do método "Dice and Fill". Esse trabalho apresenta a teoria necessária para entender como funciona o desgaste por abrasão em cerâmicas e quais as variáveis que mais influenciam nesse desgaste. São apresentados também os requisitos e as características do corte que devem ser feitos nas piezocerâmicas, bem como os cálculos de dimensionamento da taxa de desgaste através da fórmula de desgaste de Archard. Através dos resultados experimentais e práticos essa dissertação mostra como regular o equipamento para funcionar em sua máxima eficiência.

Abstract in English
The objective of this work is to describe one great and simple mechanism that is capable of machining PZT ceramic by wear. That mechanism will be used to produce piezocomposites transducers more easily by the "Dice and Fill" method. This work also explains how the ceramic material can be worn and which variables are important in this wear. It is also presented the requirements and characteristics of the ceramic cuts to build an ultrasonic transducer and showed how to predict the wear in the ceramic by using the Archard's formula. Finally all parts of the cut mechanism are described and the practical results of the study are used to setup the mechanism to work in the maximum efficiency.
