Compared with the traditional uniform pressure coils, flat spiral coils have simpler structure and longer service life, as well as appropriately uniform electromagnetic force on sheet. Therefore, in this study, a flat spiral coil is used for the micro-forming of thin sheet metal. The effects of discharge voltage (U), cushion block thickness (H), and number of discharge times . This partially explains the enhanced strength of the micro-grooved sheet after micro-rolling forming. 35, 36 As shown in Fig. 25 (c) and (d), after incremental forming, regardless of whether there are microgrooves or not, the relative frequency of the two orientation peaks of {10 1 ¯ 2} tensile twins and {11 2 ¯ 2} compressed twins are .Investigations into metal micro-forming technology have been developing over the last 20 years.

In metal micro-forming process, the material deform behaviour is influenced by the grain size, grain orientation and feature size. The most common used parameters to describe the material behaviour are the flow stress and the flow curve, while they determine the forming forces, the load on the tools, the local flow behaviour and thus the filling of the die. In order to investigate the springback behavior of brass in micro sheet metal forming processes, an efficient and low cost 3 point bending experiment was conducted. Thicknesses and average grain diameters of brass 26000 1/2 Hard (H02) were controlled to achieve a range of desired T/D (thickness/average grain diameter) ratios. Saotome and Okamoto (2001) firstly investigated micro incremental sheet forming (μ-ISF) process and developed a system based on SEM to achieve the in-situ observation of the forming process. Later, . Since the metal sheet and the embossed die is partial contact when h is 64 µm, this partial compression stress state increases the uncertainty .
Micro sheet metal formingMicro sheet metal forming was investigated in terms of air bending and laser bending of metal sheets with a thickness of down to 0.1 mm by Kals and Vollertsen [16], [17]. They pointed out that in laser bending operations for thick sheets steep temperature gradients lead to bending, whereas thin sheets are bent by the .Micro Metal Forming, i. e. forming of parts and features with dimensions below 1 mm, is a young area of research in the wide field of metal forming technologies, expanding the limits for applying metal forming towards micro technology. .
