Abstract
The titanium alloy Ti-6Al-4V is one of the most frequently used materials for biomedical applications due to its biocompatibility and excellent mechanical properties. However, wide usage of Ti-6Al-4V sheet is limited by its poor room-temperature formability. Therefore, hot Single Point Incremental Forming (SPIF) has been used to improve its formability. This paper aims at proving the feasibility of the hot incremental forming of an acetabular component of hip prosthesis by Finite Element simulations. The effect of process parameters, namely the forming temperature and the punch diameter on the geometric accuracy and the failure of the final product are investigated.
Highlights
Single Point Incremental Forming (SPIF) is a variant of incremental forming suitable for prototyping and small batch production due to its flexibility and low tool effort
The research included two different materials: carbon and stainless steel. They concluded that the new procedure enabled an additional mass reduction of the dental base which is highly desirable from viewpoint of patient and comfort of wear
The present paper aims to provide a preliminary numerical study of hot single point incremental forming technology using the commercial finite element computer program ABAQUS
Summary
Single Point Incremental Forming (SPIF) is a variant of incremental forming suitable for prototyping and small batch production due to its flexibility and low tool effort. Fiorentino et al [7] manufactured a plate prosthesis using a titanium alloy and Polycaprolactone (PCL). Their results were promising, an optimization of the process parameters should be done in order to increase the accuracy of the part. The research included two different materials: carbon and stainless steel. They concluded that the new procedure enabled an additional mass reduction of the dental base (the final sheet thickness is 0.5mm instead 0.8mm of the original thickness) which is highly desirable from viewpoint of patient and comfort of wear
