Abstract:

Mechanical micro deep drawing becomes a more and more industrial relevant process. But due to size effects new challenges are involved in this process compared to macro deep drawing. The size effects cause an increase of friction and thus hinder the material flow. The change of friction in mechanical micro deep drawing is subject of the presented investigations in this paper. Additionally to this, a new non-mechanical micro deep drawing process is presented, whereby a laser beam acts as a punch. This new laser deep drawing process is based on a totally different mechanism compared to thermal laser forming, e.g. forming by laser induced thermal stresses: The laser produces a pulse with an extremely high power density, which causes plasma generation at the target and thus a shock wave. The shock wave can be used as in explosive forming, but is smaller and easier to generate. Recent investigations showed that using this technology laser deep drawing is possible with a sheet metal out of Al 99.5 and a thickness of 50 'm. The deep drawing process was carried out with a die diameter of 4 mm and shows promising results.

Abstract:

Micro hydro deep drawing is a promising technology to fabricate micro metal products with complex 3D shapes. However, the size effects in the micro hydro deep drawing become considerable and significantly influence shape accuracy of drawn cups. In this study, a Voronoi micro scale simulation model was developed to consider the size effects of SUS304 foils. A surface layer model was additionally applied in the simulation to further explain the size effects. The micro hydro deep drawing experiments were conducted with annealed SUS304 foils and the drawn cups were examined. The wrinkling phenomenon was generally aggravated with the hydraulic pressure. Simulation results also show that the high hydraulic pressure does not improve the shape accuracy of the drawn cups as that in the normal scale hydro deep dawning process does. The simulation results are in accordance with the experimental results.

Abstract:

Flexible forming technology provides significant application potential in the manufacturing of complex shaped components even at miniaturized levels. The most attractive characteristic of this technology is simplicity, and its feasibility for prototype processes and low-volume production. The main purpose of this study is to clarify the decisive characteristics of micro deep drawing of metallic foils by using flexible forming technology. In this work a new technique is adopted using rigid punch, rigid holder and rubber pad, so that a particular gap is allocated between the blank holder and a fixed plate to allow the rubber pad to expand through it. The key process parameters studied here are rubber hardness, rubber-pad dimensions, drawing velocity, and initial gap value. Stainless steel 304 foils are used with thickness of 0.1mm. To investigate the effect of soft material properties, urethane rubber with hardness of 20, 40 and 60 shore A is utilized. Also, the punch diameter used in this study is 4mm. Moreover, many drawing experiments are conducted with punch velocities range of (0.1mm/s-100mm/s) to show the effect of process velocity. FEA using the commercial software ABAQUS/Standard is used to simulate the drawing process at micro scale. A hyperelastic material model is adopted to define the flexible pad and an elastic-plastic model is defined for the blanks.

Abstract:

As a result of the remarkable demands on electronic and other portable compact devices, the need to produce various miniaturized parts, particularly those made from metallic sheet is growing. In other words, in order for manufacturing companies to stay in competition, they are required to develop new and innovative fabricating processes to produce micro components with more complex features and a high standard of quality and functionality. Microforming is a micro fabrication process that can be employed efficiently for mass production with the advantages of greatly minimizing material waste and producing highly accurate product geometry. However, since the clearance between the rigid tools, i.e. punch and die, utilized in microforming techniques is relatively very small, there is a high risk of damaging the tools during the forming operations. Therefore, the use of forming tools made of flexible materials in sheet metal forming processes at micro scale has powerful potential advantages. The main advantages include a reduction in the production cost, eliminating the alignment and mismatch difficulties, and also the creation of parts with different geometrical shapes using the same flexible tool. As the workpiece is in contact with a flexible surface, this process can significantly improve the quality of the obtained products. Despite these clear advantages, micro flexible forming techniques are currently only utilized in very limited industrial applications. One reason for this is that the deformation behaviour and failure mode of sheet metals formed at micro scale are not yet well understood. Additionally, the experience-based knowledge of the micro-forming process parameters is not sufficient, particularly when flexible tools are used. Hence, to advance this technology and to improve the production quality of formed micro parts, more investigation of the key process parameters related to the material deformation are needed. The main contribution of this work is the development of a novel technique for achieving micro deep drawing of stainless steel 304 sheets using a flexible die and where an initial gap (positive or negative) is adopted between the blank holder plate and an adjustment ring utilized in the size-scaled forming systems developed for this purpose. The interesting point here is that this study presents the first attempt of employing flexible material as a forming die tool in the micro deep drawing technology to produce micro metallic cups at different scaling levels. Polyurethane rubber materials are employed in this study for the forming flexible die with various Shore A hardness. Also, the stainless steel 304 sheets utilized for the workpieces have different initial thicknesses. Various parameters that have a significant influence on the sheet formability at micro scale are carefully considered, these include initial gap value, rubber material properties, initial blank thickness, initial blank diameter, friction coefficients at various contact interfaces, diameter and height of the rubber die and process scaling factor. The size effect category of process dimension was also taken into account using similarity theory. Three size-scaled micro deep drawing systems were developed correspondingly to three different scaling factors. In each case, finite element simulations for the intended micro drawing systems are performed with the aim of identifying optimum conditions for the novel forming methodology presented in this thesis. The numerical models are built using the known commercial code Abaqus/Standard. To verify the microforming methodology adopted for the proposal technique as well as to validate the predictions obtained from simulations, an appropriate number of micro deep drawing experiments are conducted. This is achieved using a special experimental set up, designed and manufactured to fulfil the various requirements of the micro-forming process design procedure. The new knowledge provided by this work provides, for the first time, a predictive capability for micro deep drawing using flexible tools that in turn could lead to a commercially viable production scale process.

Abstract:

O processo de microestampagem permite a fabricação de peças ou microcomponentes, podendo ser aplicado a diversas áreas da engenharia. Logo, este trabalho tem por objetivo desenvolver um micromotor de passo e avaliar os efeitos da miniaturização de seus componentes. A simulação computacional foi utilizada neste trabalho de forma a avaliar os defeitos surgidos com a miniaturização, através do software de elementos finitos DYNAFORM com “solver” LS-DYNA. O material empregado na carcaça foi o aço de baixo carbono ABNT 1010 e o aço inoxidável ABNT 304, e para o núcleo magnético do micromotor, composto pelo rotor e estator, utilizou-se o aço elétrico ABNT 35F 420M. A simulação computacional, além de identificar os problemas oriundos da miniaturização dos componentes, também foi utilizada para otimizar as ferramentas de microestampagem, demonstrando desta forma ser uma grande aliada para o desenvolvimento do processo. O processo de corte convencional em matriz não foi aplicado no corte do rotor e do estator, pois produziu defeitos como empenamento e rebarbas. Ao invés disso, empregou-se o processo de corte por eletroerosão a fio, que produziu peças planas e superfícies lisas.<br>The process of micro deep drawing is a micro-technology which allows the fabrication of microcomponents and can be applied to various fields of engineering.

A computer simulation was carried out in order to evaluate miniaturization of the components trough the finite element software DYNAFORM with “Solver” LS-DYNA. The material used in the motor housing was low carbon steel ABNT 1010 and stainless steel ABNT 304. However, in magnetic core, comprising the rotor and stator, the electric steel ABNT 35F 420M was employed. Micro deep drawing tools were developed based on the results obtained through simulation is a great ally to create microcomponents. The cutting process in the matrix was not employed to cut de rotor and the stator, because it produced defects such as warping and butts along the surface. Instead, wire cutting spark erosion was used and resulted in hat part and surfaces.

Abstract:

碩士<br>國立高雄應用科技大學<br>模具工程系碩士班<br>94<br>The micro deep drawing based on the technology of die forming is one of methods to fabricate micro cup-shaped and seamless metallic components. It can be used to manufacture the components for light, thin, short, and small products. This study uses a commercial package, AutoForm, to simulate the micro deep drawing processes of the copper(C1100) cups with a diameter of 3 mm. Two different thicknesses of 0.05 and 0.2 mm are considered. The study employes the Taguchi method to investigate the effects of the process conditions on the drawing ratio in the micro deep drawing. These conditions include the radii of die and punch, the clearance between the punch and the die, the blank holder force, the friction coefficient, the thickness to blank diameter ratio. Traditional die design experiences are used to select five levels of the process conditions for arranging the orthogonal array. The results show that the thickness to blank diameter ratio is the most important factor to increase the drawing ratio, and the friction coefficient is secondary factor. The depth of the drawn cups is reduced as the diameter of the blanks is increased in both cases using the sheets with 0.05 and 0.2 mm thickness. By using the 6 mm diameter blanks with appropriate process conditions, it is possible to complete the micro deep drawing processes of the cups without fracture for both cases with the different thicknesses of sheets. According to the best process conditions resulting from the simulations and the Taguchi method, a set of dies is designed for the experiments of micro deep drawing. The experimental results show that the drawn depth is about 0.7 mm and fracture easily occurs as the drawing ratio is set to 2 for the cases using the sheets with 0.05 mm thickness. These experimental results are different from the simulated ones and a further study is needed. For the cases with 0.2 mm thickness sheets, the drawn depth of the cups is about 2.76 mm and the earing effect is not significant. The results are close to those from the simulations.

This study uses the Taguchi method and a commercial package, AutoForm, to analyse the effects of process conditions on the depth of the drawn cup in micro deep drawing. The brass (JIS C2680) sheets with the thickness of 0.2 mm were used to produce the micro cups with the diameters of 3 mm and 1.5 mm, respectively. The investigated process conditions include the diameter of the blank, the radii of die and punch, the blank holder pressure, the punch speed and the clearance between the punch and die. The results show that the diameter of the blank, the radius of the punch are the main parameters affecting the depth of the drawn cup in the micro deep drawing process.

碩士<br>淡江大學<br>機械與機電工程學系碩士班<br>97<br>In this study, the dynamic-explicit finite element program was applied to analyze the forming process in the micro deep drawing of cylindrical cup. The present study discussed the relationship between punch load and punch stroke, the deformation history, distribution of height of cup, distribution of von Mises stress and strain for various arc radii of tools. The reliability of the finite element program could be proved by the comparison between numerical analysis and experiment. There were three experiments for this study. First, the material parameter of electrolytic copper foil was obtained by micro-tensile test of ASTMD-412-F specification for experiment. The maximum true stress was about 359.99MPa and the maximum true strain value was 0.128. Then, the kinetic friction coefficient was obtained by the friction test of ASTM-D1894 specification. The kinetic friction coefficient of punch and holder relative to blank was 0.111, and the one of die relative to blank was 0.102. Finally, the six different geometric sizes of tools were designed to compare with numerical analysis results for experiment of micro deep drawing of cylindrical cup in this study. According to the comparison results between numerical analysis and experiment, the maximum punch load decreased as the arc radius of punch increased. When the arc radius of die decreased, the wrinkles of workpecies decreased, and the second load disappeared during the micro deep drawing process of cylindrical cup. The height of cup increased as the arc radius of punch increased. The dynamic-explicit finite element program could simulate the micro deep drawing of cylindrical cup reasonably in this study.

The small parts makes the material properties and stamping formability not the same as traditional metal stamping. In order to solve forming problems, improving the drawing formability is necessary. This paper develops an optimal design for micro-dimples on the surface of blank-holder to address the issue of defects in metal forming. During this research, we investigate the Micro-Dimples on Blank-Holder during Deep Drawing Process. The geometric parameter including diameter, area ratio and depth. The deep drawing experiment is achieved by Tauchi methods. Experimental results show that the drawing by dimple texturing with diameter of 100 μm,area ratio of 20 percent,depth of 15μm have the best formability. The height of forming compare with no micro dimples increase 26.9 percent. However,the micro-dimples on blank-holder of DLC films have optimal formability of drawing,increasing 0.01mm. According to the ANOVA analysis, the most significant factor is depth (32.62%), the second is area ratio (29.13%), the third is diameter (28.79%). In addition, after coating diamond-like carbon (DLC), the ANOVA analysis show that the most significant factoris depth (48.13%), the second is diameter (45.78%), and the most insignificant factor is area ratio(0.58%).

The development of manufacturing technologies of the parts is thus broadly attracted. Micro metal forming processes have characteristics of high product rate, good quality of products and improvement on mechanical properties. The processes are also suitable for mass production with low costs. They have great potentials on manufacturing micro metal parts. This study used annealing techniques to adjust the grain size of SUS304 stainless steel. Three sheets with different thicknesses 0.05, 0.1 and 0.2 mm were used in the micro deep drawing process for producing2 mm diameter cups. The purpose of the study was to investigate the grain size of the stainless steel on the micor deep drawing. The study developed a micro deep drawing system for preforming the processes under different forming conditions. The surface roughness, rim height varation and thicknessvariation of the draw cups were carefully examined. The results show that the grain size does affect material flows. The sheets with fine grains lead to homogeneous material flows, and thus result in less dimension varations and good surface quality of the drawn cups.

Abstract:

碩士<br>國立高雄應用科技大學<br>模具工程系<br>103<br>Most studies on microforming focus on the effect of grains on the formability. There have been rare publications emphasizing the influence of surface textures. Surface texture becomes influential on the sheet outline geometry when the thickness gauge decreases to the range of grains. This work investigates the influence of surface textures on the micro drawing of spherical bottom. The metal sheets were imprinted with textured rolls. Both simulation and experiment were conducted. Copper sheets with three thickness gauges 0.2, 0.1 and 0.05 mm were used in this study. Longitudinal, transverse and isotropic surface lays were obtained through a pair of printing rolls. The textured sheets were drawn to diameters of 8, 4 and 2 mm of spherical bottom, which correspond to macro, meso and micro forming conditions, respectively. DYNAFORM software was used to obtain the reasonable drawing ratios of the respective forming conditions. The effect of friction condition on the thinning of drawing was also evaluated. DEFORM software was used to analyze the effect of longitudinal or transverse surface lays on the drawing performance. The result of simulation was verified with experiment. Both simulation and experiment show that the earing will change in the drawing of different surface textures. The macro forming condition with 0.2 mm thick sheets does not change with the variation of surface textures. The meso forming condition with 0.1 mm thick sheets exhibits concave geometry in the accumulation zone. The micro forming condition with 0.05 mm thick sheets is significantly affected by the surface texture. Wrinkling appears in the accumulation zone. Moreover, the variation of thickness becomes substantial in the thin sheets, and the thinning during drawing cause tearing on the workpiece. Therefore, surface texture becomes an influential factor in micro forming of thin sheets. Drawing load is minimal with the isotropic lays for the three macro, meso and micro forming conditions. This is attributed to the lubricant pockets provide sound lubrication and cause lower forming load. There are problems with leakage in the longitudinal or transverse lays. The lubrication deteriorates and the forming load increases.

碩士<br>國立臺灣科技大學<br>機械工程系<br>101<br>Micro metal forming technology has been widely used in various industries. The thickness of sheet is reduced due to the trends of miniaturization of products. To clarify the plastic behavior of very thin sheet, micro deep drawing experiments with 304 stainless steel sheets of 0.05, 0.075 and 1mm thickness was conducted. In addition, finite element analysis was also carried out to predict the plastic flow and the formability. The stress-strain distribution of micro cups under deep drawing process was analyze and discussed. Moreover, the LDR (ratio of blank diameter to punch diameter) was detected. The results of experimental and numerical showed a good agreement. Moreover, ultrasonic variations was imposed to the micro deep drawing process to increase formability of stainless steel 304 foils.

Abstract:

Effects of starting microstructure on deformation behavior of commercially pure Ni blanks during micro-deep drawing was studied utilizing microforming set up that sits inside the chamber of Scanning Electron Microscopy (SEM) enables in situ observation of material flow during deformation. Various microstructure fields were created in Ni blanks using Severe Plastic Deformation (SPD) and heat treatment. SEM based Digital Image correlation (DIC) technique was used to characterize the micromechanics of deformation and its relation to process outcomes/performance. Pre and post–deformation microstructure analysis was carried out by performing Orientation Imaging Microscopy (OIM) to track the microstructure evolution across the micro-formed blanks during deformation in order to identify the process anomalies originated from the characteristics of starting microstructure and its interaction with deformation mechanics. We showed that microstructurally graded sheets consisting of nano-grained/coarse-grained layers significantly improves the formability of micro-blanks and effectively delays strain localization and onset of instability/failure during micro-deep drawing.
