Estudo da usinabilidade das ligas de alumínio: uma avaliação com base no teste de propriedades físicas

Abstract

The machinability of the material is its intrinsic properties, on the tool material and is correlated by various cutting conditions and parameters, including tool life, cutting temperature, shear rate, surface finish the workpiece, cutting speed, etc. This study aims to present a theoretical framework on the machinability of metal materials. The objective of this study machinability of some metals is demonstrated by the results of machinability tests in speed units based on a test that does not require machining, the physical properties test. The various types of aluminum alloys were investigated , their characteristics, and variants of the machinability index linking them to the cutting parameters. The basis of testing the test was given based on studies of Henkin, following the line of the types of cataloged physical properties. The properties of selected metals and units being determined, was set up a database to compare them and thus use them in the test proposed in the study. The tests were developed by a data processing software program through reset by numerous spreadsheets re calculations based on the general equation machinability with formulas and optimization, for the input variables and the processing to generate expected values and representative graphics and thus obtain the machinability indexes for the selected aluminum and alloys
