One of the key application areas of Single Point Incremental Forming is in the
manufacture of parts for bio-medical applications. This paper discusses the challenges associated
with the manufacture of cranio-facial implants with extreme forming angles using medical grade
titanium sheets. While on one hand, the failure wall angle is an issue of concern, the parts also need
to be manufactured with accuracy at the edges where the implants fit into the human body.
Systematic steps taken to overcome these challenges, using intelligent intermediate part design,
feature analysis and compensation, are discussed. A number of case studies illustrating the
manufacture of accurate parts in aluminium, stainless steel and titanium grade-2 alloy are discussed.
