Desenvolvimento de uma mesa de coordenadas XY CNC para corte a plasma

Abstract

The sheet metal cutting process is widely used in industrial processes, being classified as mechanical, thermal or abrasive. In recent decades was large used the manual cutting of sheet metal which is being replaced by automated cutting, thus, increasing production, dimensional quality and finish. This paper approach a thermal cutting system, known as plasma cutting, making an adaptation of a manual plasma torch to a xy computerized numerical control (CNC) table. The aim of this work is to design and build a CNC table to meet the lack of equipment that provide this type of working in the welding laboratory of the university UTFPR -PB. In this study, was conducted a literature search regarding the main devices that make up a CNC machine and plasma cutting. The development of the xy table, was followed a machine design methodology identified in literature which is based on ten stages of development. Finally, was built a prototype of numerically controlled xy coordinate table and some tests such as speed and accuracy test with positive results were achieved in these aspects.
