A multi-axial electromagnetically actuated punch for cutting micro-components

In this paper a multi-axial electromagnetically actuated punch is presented. This punch can apply forces up to 60 kN and has a maximum stroke of 4 mm. Especially, the punch is qualified for manufacturing micro-components demanding high accuracy and high stroke rates. Due to its multi-axial drive concept, the punch is able to compensate the tilt of the ram during the cutting process. Thus, abrasion at the die is reduced and the punching quality is improved. Therefore, two multiaxial control concepts are introduced and compared based on experimental results.
