TL;DR: A reverse engineering approach associated with single-point incremental forming process in order to produce a titanium prosthesis of human skull is developed, which allows guaranteeing the high degree of customization required.
Abstract: The single-point incremental forming process is an emerging process, which presents an alternative to the conventional sheet metal-forming processes like stamping and drawing. It is known to be perfectly suited for prototyping and small series. The incremental forming process offers the possibility of manufacturing medical prosthesis or implants specific to each patient, which are more comfortable and guarantee better performance. A reverse engineering approach associated with single-point incremental forming process in order to produce a titanium prosthesis of human skull is developed. It allows guaranteeing the high degree of customization required. In this paper, several novel warm forming experimental setup equipped with instruments to measure efforts and temperature monitoring is proposed. This new warm setup is feasible and makes it easy to monitor force and temperature sheet at forming; it gives it the ability to be exploited in the industry of manufacturing titanium alloy medical shapes. The real geometry of a skull prosthesis is re-constructed from a laser scanning technique, and specific treatments are performed until a CAD model is obtained. From it, the forming punch trajectories have been defined, and skull prostheses are manufactured using the technology of single-point incremental forming in titanium material at different temperatures.

TL;DR: In this article, a method for piercing a tube during liquid impact forming or hydroforming to form a hole with minimal deformation in the material surrounding the hole is described. But the method requires the tube to be filled with liquid, and the tube must be stamped with liquid to increase the internal pressure of the tube.
Abstract: A method for piercing a tube during liquid impact forming or hydroforming to form a hole with minimal deformation in the material surrounding the hole. The method includes the steps of: (1) filling the tube with liquid; (2) stamping the tube thereby increasing the pressure of the liquid within the tube; (3) piercing the tube while the pressure is elevated with a tapered punch whereby the material around the pierced hole is pushed back toward the die wall due to the elevated internal pressure of the tube; and (4) retracting the tapered punch from the tube with the face of the punch catching on the tube wall to pull the material back toward the die wall.
