Electromagnetic punching (EMP) is a new type of high-speed punching technology. In the existing EMP method, the blank has no initial loading velocity, so the punching force can only be increased by boosting the discharge energy, which greatly reduces the energy utilization and limits its application in high-strength thin sheet punching. To this end, this paper proposes and validates an EMP method with adjustable initial collision velocity based on the inner-field uniform pressure actuator (UPA) for manufacturing punched parts of TA1 pure titanium foil sheet. The results show that with the increase of collision velocity, the punchable aperture range expands, the dimensional accuracy and section quality of punched parts are significantly improved, and a punchable window is established. In addition, based on the dynamic material constitutive and fracture model, the electromagnetic-structural field simulation model of EMP is established. The analysis shows that the formation of the fracture section is the result of the combined effect of tensile stress and shear stress, and the increase of the collision velocity improves the section quality. Finally, a 100 μm thick titanium sheet with a hole diameter of 2–16 mm and a maximum dimension accuracy of less than 10 μm was successfully punched.
