Abstract

TPIF-RL method is a new method that gives better wall thickness in incremental forming. In this method, the sheet is not fixed at the edges. Like the deep drawing process, it is compressed with a certain pressure. During the forming process, the sheet flows under the blankholder. Thus, more homogenous wall thickness is ob-tained.
In this study, Titanium Grade 2 sheet is formed as a cone via TPIF-RL method. Optimum forming parameters were determined by Signal/Noise analysis. In addi-tion, finite element analysis of the process was performed. Using 2 bar clamping pressure, 1000 mm/min feedrate, 0.75 mm increment and 15 mm forming tool di-ameter optimum result was obtained. With these optimum parameters, 6% thin-ning occurs on sheet thickness. This new method ensures a homogeneous wall thickness distribution.
