Abstract
The purpose of this article is to present a comparison of the SPIF conformation with heating between the aluminum alloy sheets 1050 and 6063, with 1.0 mm and 1.2 mm thickness respectively, in order to verify the processing parameters for alloys and thickness of different sheets thus validating the process of SPIF with heating. The hot forming is due to the type of geometry to be used, complex geometry, using a high combined rotation heating and halogen lamps, thus exceeding a temperature of 210 ° C. Also, tests with low rotation were carried out to verify the influence of rotation in the incremental forming process with heating. As a result, it was observed the possibility of conformation of complex pieces with rich detail in both materials. However, for aluminum sheets 6063 of 1.2 mm thickness due to its higher tensile strength, it was necessary to pay special attention to the lubrication of the process to avoid rupturing of the sheets due to lack or inadequate lubrication of the process. It was also verified that it is important to verify the relationship between the size of the tool and the details to be conformed in the part, as this directly influences the quality of lubrication necessary to conformation of these small details.
