ADVANCEMENTS AND CHALLENGES IN INCREMENTAL FORMING: A COMPREHENSIVE REVIEW OF PROCESS OUTPUTS

Abstract

This paper describes earlier studies on the advantages of the incremental sheet forming
process. Types of this process are Single-Point Incremental Forming (SPIF), Two-Point
Incremental Forming (TPIF), Multi-Point Incremental Forming (MPIF), Double-Sided
Incremental Forming (DSIF) and Incremental Sheet Folding with its advantages and
applications. It has been shown that the two types of single-point and two-point operations
are the most used by researchers, and this depends on the application. These processes are
characterized by the fact that they do not require mold or support, so they are considered
one of the best processes for manufacturing complex and small parts within a short period
of time compared to traditional forming processes. These processes are suitable for
different types of materials, including metals, polymers, and ceramics, but not alone, but
rather as a composite material with metals. As a literature review some of the process
parameters that affected on process output such as, formability, forming force, accuracy
and surface roughness were discussed. Final thoughts on the literature found through this
review will serve as the researchers' foundation for added investigation.
