Incremental forming of Titanium T40 sheet: experimental and numerical investigations
Abstract
Single point incremental forming process (SPIF) has a great potential to manufacture small series of customized products. During SPIF process, the sheet metal is clamped and locally deformed, in an iterative way, by a hemispherical tool that follows a specified trajectory. The use of industrial robots to implement this process aims to improve its flexibility (increased volumes of work and complexity of the formed parts) and to reduce its cost. For these mechanical systems, for which the structural rigidity is low, the prediction of forming forces associated to an elastic modeling of the robot is necessary to compensate tool path errors due to the robot compliance and to ensure the geometrical quality of the final part. The forming forces can be predicted from a finite element simulation of the process and used then as input data to the elastic modeling of the robot. However, the accuracy of the calculated loads depends strongly on the constitutive material behavior of the blank introduced in the simulation of the SPIF process. In this context, the aim of this study is to evaluate the ability of a simple elasto-plastic model, identified from conventional tensile tests carried out on a T40 titanium alloy, to predict the forming loads used to manufacture a truncated cone. The evaluation of the model is performed by comparing numerical predictions with the experimental results (efforts and geometry).
