displacement curve, cf. Fig. 6a. The experimental results are in good agreement to the analytical results, cf. Fig. 6b. Hence, work losses by channel depth are assumed to be low.
Figure 6: Straight reference channel; [...] method. Testing of spherical as well as cylindrical micro samples with initial diameters between 0.6 mm and 2.0 mm was successfully performed. As the forming energy was not transferred within one step [...] position of the part was measured through the optical access in situ with a digital microscope (Leica DVM6). Due to diffraction at the edge of the lid, the
