Purpose - To study the influence of process and product parameters on the properties of products in incremental sheet metal-forming; to create models for process optimisation and to introduce an approach to incremental forming process optimisation. Design/methodology/approach - A new flexible sheet metal-forming technique, incremental forming, has been studied. The technique can be viewed as a rapid prototyping/manufacturing technique for sheet metal parts. To analyse the process, an experimental study and finite element analysis were performed. For the optimal design of incremental forming process non-linear mathematical programming was used. To estimate the limitations and main parameters of the process, a complex model was developed. Findings - Introducing optimisation procedures for the incremental forming process allows users to increase productivity and to assure quality. Research limitations/implications - As finite element analysis of the process is time-consuming in real life situations, a future study should include creating analytical models for process modelling. Practical implications - The described approach can be used in practice to improve competitiveness of companies producing sheet metal prototypes. Originality/value - This paper offers guidelines for shortening processing time of sheet metal prototypes for engineers and researchers. The optimisation that is based on experimental/theoretical/numerical models of incremental forming process has not been covered before in the scientific literature. [ABSTRACT FROM AUTHOR] |
