Resumen:
Over time the process of incremental deformation of sheet metal without
matrix in its variant (SPIF), has been developed in different countries
with the aim of meeting the needs of flexible production with no
investment in tooling and low production costs. As in any manufacturing
process is important to obtain a surface quality of the part that meets
customer needs, this variable is evaluated by the average roughness
(Ra). For this reason the purpose of this study is to investigate the
influence of the variation of three process parameters and determine
which of them contributes in greater proportion to the change in the
average roughness (Ra) measured parallel and perpendicular to the path
followed by the tool. Besides this, it wants to validate the impact that
has the spindle speed in the analyzed variable and the orange peel
defect. To this end, a full multifactorial design of experiments with
three factors and two levels () and three replicates were performed, in
order to obtain greater reliability in the model. Subsequently, an
analysis of variance is executed and the results are formalized, finding
which parameters influence more than others in changing roughness and
how the orange peel defect depends on the spindle speed. Additionally,
the results are compared with the authors cited. The aspects developed
in this study highlight the importance of improving quality variables in
any field of sheet metal processing in the international industrial
environment.
