Description 502-508
Incremental Sheet Metal Forming (ISMF) is an innovative manufacturing technique for producing prototypes and
manufacturing of complex shaped sheet metal parts. Manufacturing of implants and prosthesis for biomedical applications is
a challenging task, because it demands the fabrication of complex intricate structures replicating the shapes of human body
parts. An attempt has been made to clearly describe the capabilities and limitations of a new manufacturing technology to
fabricate low cost, specific design medical implants. This study aims to fabricate an implant for medial tibial condyle using
single point incremental forming and thereby improve the suitability of the single point incremental forming process. This
investigation reports the fundamental knowledge on mechanical behavior of titanium grade 2 sheet metal to design and
fabrication of knee implants with rigid hemispherical and roller ball forming tools by means of single point incremental
forming process. Influence of major process parameters such as forming force, deformation of sheet, sheet thickness and
profile accuracy of part have been identified by experimental work and Finite Element (FE) simulations. The result has
shown that surface finish of the part formed by the roller ball forming tool is better than hemispherical rigid tool.
