On Micro Forming by Hydro Spark Forming Method
Materials Science Forum, 2007This paper proposes a seamless microforming technique from 100 micrometer order bulging all the way down to micrometer-order embossments by using hydro spark forming method. Sub-millimeter order bulging with 300 and 100 m diameter aluminum thin foils are demonstrated to be easily available without accurate positioning as in the conventional methods ...

Superplastic micro-forming of microstructures
Proceedings IEEE Micro Electro Mechanical Systems An Investigation of Micro Structures, Sensors, Actuators, Machines and Robotic Systems, 2002Superplastic micro-forming processes have been applied to forming and fabrication of micromechanical components. Selected materials are a fine grained superplastic Al-78Zn alloy, pure iron as a transformation superplastic material, and amorphous LaAlNi, ZrAlCu alloys which exhibit a supercooled liquid state. With these materials, microformability tests

Steel Research International, 2010
Metal forming has for many years maintained its position as the most efficient method of shaping metals and alloys. The possibility of controlling the properties of final products by careful control of the condition of deformation is now the principal advantage of metal forming which makes this technique competitive.

A miniaturized machhine for micro-sheet forming
International Journal of Material Forming, 2010A new miniaturized machine was developed for micro-forming of thin sheets. A piezoelectric actuator was used to give the stroke and a load cell to support the die. This way, the punch position and speed were precisely controlled and the forming forces were measured during processing.

Size effects are effects which might occur, if the dimensions of a forming process are scaled up or down. They might enable or disable the application of a process in the micro range. Based on the systematic order of size effects, which defines density, shape and structure effects, one example for each group is given.

Punching of noncircular micro-holes and development of micro-forming
Precision Engineering, 2007In this paper, vibration-EDM technology was introduced by the vibrating worktable designed to fabricate noncircular micro-electrodes and micro die-openings using wire electro-discharge grinding (WEDG). Micro punches and micro die-openings with different clearances were fabricated by controlling the spark gap in micro electrical discharge machining ...

Tribological behavior of micro structured surfaces for micro forming tools
International Journal of Machine Tools and Manufacture, 2010Abstract Mechanical micro machining processes, like milling and grinding are appropriate technologies for the flexible production of precise molds with complex shapes for metal forming processes. In most cases machining strategies are orientated towards form accuracy of the desired forming tool only.
