Abstract

The characteristic segmented chip formation of titanium alloy Ti6Al4V leads to a periodic excitation and therefore to vibrations during the process. One way to avoid these chip formation induced vibrations is to position a counter element, the constraint, in front of the primary shear zone which suppresses the segmentation mechanism. In this paper, the simulative design of the geometry and position of the constraint, which are decisive for the successful suppression of the segmented chip formation, is shown. The most promising design is then manufactured and used in experimental investigations and the results are compared with those from the simulations.
