Uso de chapa de zinco no processo de estampagem incremental variando o fluido lubri-refrigerante

Abstract

This study aims to evaluate the behavior of zinc sheets for the single point incremental sheet forming process under four different lubricants. This stamping technique has gained prominence because it allows forming in CNC machining centers, without the need of a specialized tooling, which allows the process of sheet forming at a relatively low cost. The tests were first carried out by the design of the geometry in a CAD / CAM software and later the execution of the sheet forming in a CNC machine. The results indicated zinc as a material of good formability. Roughness tests were conducted to evaluate surface quality, a slightly better surface quality has been observed for graphite lubrication.
