Abstract
In this paper, a systematic approach to investigate the effect of some relevant
process parameters on thickness variation aspect in incremental sheet metal forming
(ISMF) process has been studied. The thickness variation aspect was investigated by
disclosing the effects of four discrete process parameters: number of forming passesχ 1,
typology of forming speed χ2, direction of tool travel relative to the rolling direction χ3,
and typology of tool path χ4. The proposed systematic approach utilizes design of
experiment (DOE) and analysis of variance (ANOVA) as a base to study the effects of
four process parameters and different influential combinations. The analyses results
have shown that number of forming passes χ1, and direction of tool travel relative to
the rolling direction χ3 have greatest effect on the thickness variation. It is
demonstrated that the response table and response graph, main effect plot, analysis of
variance ANOVA and predictive model generation are powerful systematic procedure
to disclose the impacts of the process parameters on the thickness variation.
