Tool Path Strategies for Single Point Incremental Forming
In the last few years the interest in Incremental Sheet Forming (ISF) has considerably grown due to the possibility of obtain small production batches and high customized products. Despite the increasingly knowledge of this processing technique, there are still some important process parameters that require further development. One of the most important parameters when experimental or numerical studies of ISF are carried out is the tool path programming. The decision of the strategy that will be followed can affect the accuracy, the surface finishing, the forming forces, etc. The analysis of these relationships has been studied for several authors using different tool path. In the present paper different tool path strategies for the same geometry are compared. The geometry has two inclination wall angles. Also, different commercial softwares are employed to develop the tool path of the desired geometry. The main objective of the paper is to identify some indicators that can assist in the choice of which strategy is the best, not only depending on the complexity of the geometry or the software used but also on qualitative criteria. With all this work it is possible to provide some useful guidelines that permit to establish a selection criterion of the tool path, which will be very interesting before developing an experimental work.
