Abstract:
The present study examined the relationship between directionality of drawing movements and the orientation of drawn products in right-handed adults and young children for 27 Japanese kindergartners and 29 Japanese university students who were asked to draw with each hand fishes in side view and circles from several starting points. Significant values of χ2 for distributions of frequencies of orientation of the fish drawings and the direction of circular drawing movement indicated that adult right-handers drawing the fish facing to the left tended to draw a circle clockwise when they drew with the dominant hand, while there was no such significant relationship in young children's drawings. This result may suggest that the reading and writing habits may be implicated in the direction of drawing movements with the dominant hand, and this directional bias of drawing movement in the dominant hand can appear in the orientation of finished drawings.

Abstract:
Deep drawing is one of the most widely used metal forming process to produce sheet metal parts especially in automobile industries. Warm working is the plastic deformation of metal at temperatures below the temperature range for recrystallization and above the room temperature. In this investigation, 1.0mm thick circular specimen of stainless steel AISI 304 were warm deep drawn and the influence of temperature on the deformation behaviour of material and the drawing loads which is required to draw the component was studied. The results show that the warm working has positive effects like reduced drawing load, negligible amount of increase in thinning and thickening of a drawn component when compared to the conventional drawing and also there is no necking or cracking occurs due to the temperature influence.

Abstract:
Abstract The concept of digital manufacturing supposes application of digital technologies in the whole product life cycle. Direct digital manufacturing includes such information technology processes, where products are directly manufactured from 3D CAD model. In digital manufacturing, engineering drawing is replaced by CAD product model. In the contemporary practice, lots of engineering paper-based drawings are still archived. They could be digitalized by scanner and stored to one of the raster graphics format and after that vectorized for interactive editing in the specific software system for technical drawing or for archiving in some of the standard vector graphics file format. The vector format is suitable for 3D model generating, too.The article deals with using of selected integral transformations (Fourier, Hough) in the phase of digitalized raster engineering drawings vectorization.

Abstract:
The new method of deformative strengthening of holes using combined static and impulse loading is presented. Partial replacement of static load, used in classical burnishing, by impact impulses allows decreasing energy intensity of strengthening process and expanding the technological capabilities of the method. The method allows strengthening of small diameter and long length holes. The high depth and degree of strengthening can be obtained; the surface roughness can be decreased. The experimental complex for research of static-impulse parameters of deformative drawing of holes of machine parts, which allows determining the influence of energy parameters of the process taking into account stiffness of technological system on roughness, depth and degree of strengthening of holes surfaces, is developed.

Abstract:
In this paper we consider the important class of directed acyclic graphs (DAGs), and present the results of a comparative study on four popular drawing algorithms specifically developed for them. The study has been performed within a general experimental setting consisting of two large test suites of DAGs and a set of quality measures. The focus of the experiments has been the practical behavior of the algorithms with a geometric foundation compared to that of the algorithms with a topological foundation. The four algorithms exhibit various trade-offs with respect to the quality measures considered, and none of them clearly outperforms the others. Our analysis has motivated the development of a new hybrid strategy for drawing DAGs that performs quite well in practice.

Abstract:
Tree Drawings have been used extensively in software engineering and many other business and computer applications. The basic structure of a tree allows for the organization and representation of complex information. Many commercial tools allow their users to draw or construct trees to represent a problem and/or its solution. Our focus is on dynamic trees - trees subject to frequent changes and redisplay in highly user-friendly interactive computer applications. Tree presentations in such interactive tools have to be precise and maintainable, which means, the tree presentations should maintain a particular structure so that user's mental perception of the tree is not disrupted or changed drastically when modifications are made to the tree being manipulated. Minimal modifications to the tree should cause correspondingly minimal changes to the general layout of the tree drawing and such changes should be consistent with the original layout to enable the user to anticipate them and verify their correctness with minimal mental effort. Also, display properties, like Vext, Hext, aspect ratio and space utilization efficiency of the layout are important to the user as they influence efficient use of available drawing/visualizing space which in turn affects comprehensibility of the tree drawing in question. In this thesis report, we analyze and compare three published algorithms, proposed by Workman-Bernard[1], S. Moen[3], and R. Cohen [2],to interactively manage the layout of graphically represented dynamic trees. We attempt to measure and analyze the performance of these algorithms based on their layout properties and their computational requirements. This research concludes that the Workman-Bernard (WB) algorithm when compared with its closest equivalent, Moen's algorithm, produces trees with better layout at a significantly lower computation cost.

Esta pesquisa visa ao desenvolvimento de um protótipo de traçadora gráfica, para desenhar sobre uma superfície rígida na posição vertical. A principal aplicação desta traçadora é no segmento de comunicação visual para anúncios em grandes superfícies. Com a intenção de atingir alto grau de flexibilidade nesta utilização, a traçadora é concebida para trabalhar em coordenadas polares, dispensando um quadro fixo composto de várias guias lineares como seria o caso de uma traçadora x, y. Numa primeira parte, apresenta-se o layout básico, a construção do protótipo e as equações cinemáticas que governam o movimento. Em seguida, é feita uma análise estática da traçadora e do momento máximo requerido para movimentar o braço, visando à correta especificação dos atuadores. Com base nas equações geométricas utilizadas, foi elaborado um algoritmo de traçado que contempla as não linearidades inerentes ao problema.Vários testes com figuras geométricas foram realizados, para a avaliação do protótipo.
The present research aims the development of an experimental prototype of a plotterdesigned to work on a vertical plane. In order to achieve maximum flexibility to work on site, the plotter was conceived to operate in polar coordinates with a single fixed point.This concept simplifies transportation and assemblage of the plotter at the working location. The work discusses the kinematical equations for pen displacent, static and dynamic equation for torque evaluation as well as some design challenges which had to be overcome in order to make the plotter operational and reliable. Experimental results concerning precision and drafting velocity are presented in the work and final comments on further design improvements of the plotter are discussed in the last part.

One way to study how people design is to understand how others observe them designing. I take a step towards this understanding by examining how people segment visual design events temporally, in other words, how they divide these events into smaller pieces. I developed a methodology to comparatively study how multiple observers segment design events. In order to test my methodology, I conducted an experiment. In this experiment, I compared different attributes of a design event to see if some attributes communicate more meaning than others. From the results of the experiment, I observed that the segmentation of the design event was affected more by the gestures of the designer than by the produced designs. My observations suggest computational principles that could be used to develop computational design assistants that better understand designers intentions.

Abstract:
Trefilação é um dos processos de fabricação para a obtenção de arames, tubos e barras. Este processo consiste na redução da área de seção transversal de um material cilíndrico, fazendo-o atravessar uma matriz cônica de menor seção de área transversal, chamada fieira. Destacam-se o excelente acabamento superficial, a boa precisão dimensional e o aumento na resistência mecânica do material como vantagens e, como desvantagens, deformações heterogêneas ocorrem quando atravessam a ferramenta de trefilação (fieira). As deformações heterogêneas provocam retorno elástico também heterogêneo das camadas da barra trefilada, o que induz o aparecimento das tensões residuais relacionadas às distorções de forma, empenamentos e variações dimensionais, causando desperdício de material e energia, tanto no caso de geração de refugo, quanto em tentativas de correção das não conformidades. Desta forma, neste trabalho estudou-se a influência da geometria da fieira no valor da força necessária para realizar a trefilação e no gradiente das tensões residuais em barras de aço, através de experimentos físicos e computacionais. Após a caracterização de um processo de trefilação de um aço SAE 1045 foram desenvolvidos modelos computacionais no software Simufact.forming GP ®, e obtidos os resultados para: a força de trefilação, as tensões residuais das direções principais, as deformações plásticas, o limite de escoamento e o retorno elástico do material após a realização do processo para uma determinada redução. Os modelos foram validados através da comparação dos resultados simulados com experimentos físicos e equações encontradas na literatura. Após a validação, o modelo computacional foi utilizado para simular a variação da geometria da fieira: número de regiões de trabalho, raios de convergência entre as diferentes regiões da ferramenta, diferentes materiais e áreas de seção transversal. Os resultados das simulações computacionais foram correlacionados e utilizados para projetar e fabricar uma fieira em escala reduzida e um dispositivo mecânico para a simulação física do processo de trefilação em uma máquina universal de ensaios Emic ®. Duas diferentes geometrias de fieira foram testadas experimentalmente F1: a fieira convencional, e F4, a fieira modificada a partir das sugestões obtidas a partir da metodologia escolhida para correlacionar os resultados das simulações computacionais. As novas barras trefiladas foram caracterizadas mecanicamente através de ensaios de microdureza e rugosidade para análise das propriedades mecânicas, difração de raios-X para obtenção das tensões residuais superficiais e força de trefilação, que foi medida durante a realização do ensaio. Este trabalho contribuiu cientificamente com uma melhor compreensão do comportamento do escoamento de um material trefilado e através da análise de uma nova geometria de fieira que permitiu uma redução no valor das tensões residuais, um pequeno aumento na força de trefilação, mantendo as propriedades mecânicas do material trefilado quando comparadas com o processo original objeto desta pesquisa.
The wire drawing is a manufacturing process used to produce wires, tubes and rods. It consists in a reduction in cross sectional area by plastic deformation where the raw material (wire rod) is pulled through a die. Some of the main features of the wire drawing process are the achievement of an excellent surface finishing and good dimensional accuracies and increase in mechanical strength. However, this process generates inhomogeneous deformation due to the different flowing of the material into the drawing tool (die). The inhomogeneous deformation generates residual stress, stresses present in a material free from the action of external loads and temperature gradients. Residual stresses are commonly related to distortions of shape and dimensional variations of the final products, appearing after heat treatments which are related to shape distortions, warping and dimensional variations, causing material and energy waste, in the case of waste generation and in attempts to correct nonconformities. Thus, the influence of die geometry to reducing the residual stresses and the drawing force of bars manufactured by a cold-drawing process was studied. After the characterization of a drawing process of an SAE 1045 steel, computer models were developed in the software Simufact.forming GP ®, and the results were obtained for: drawing force, residual stresses of the main directions, plastic deformations, flow and the elastic return of the material after the process was carried out. The models were validated by comparing simulated results with physical experiments and equations found in the literature. Different die geometries were simulated as: number of tool regions, fillets between different tool regions, different materials and cross-sectional areas. The results of the computational simulations were correlated and used to design and manufacture a scale die and a mechanical device to develop the physical drawing tests in an Emic ® testing machine. Two different die geometries were experimentally tested F1: the conventional die, and F4, the modified from suggestions obtained in the computational simulations correlation F. The mechanical characterization of the new drawn bars were carried out by Vickers microhardness and roughness tests, X-ray diffraction to obtain surface residual stresses and the drawing force was taken during the test. This work contributes scientifically with a better understanding of the behavior of the flow of a drawn material by the analysis of a new die geometry that allowed a reduction in the value of the residual stresses, an increase in the drawing force and maintaining the mechanical properties of the drawn material when compared to the original process object of this research.

Abstract:
This thesis confronts the ultimate limits of perceiving the constructed world and the limits of our ability to experience architecture. The imperative of architecture is poetic: to and project encounters between matter and energy that shape the existing and bring forth the as yet unimagined to form a continuing human world. This is explored through the imagining of a habitat and vessel that projects the human endeavor of architecture into the formless depth of space. In drawing the physical from the void, the page becomes a way to move architecture from non-existence into the real by means of the imagination. An imagined wold is drawn from the void in search of the center for a universal and humanist architecture. The thesis is conceived as a vehicle for drawing the limits of perception when we attempt to imagine that which is greater than ourselves.

Abstract:
Servo presses providing flexible ram motions are extensively developed nowadays; the merit of such presses is the capability of generating versatile punch motions to fulfill the stamping. This paper studies a cup-shaped drawing process using a servo press. The aim of this research is to study the effect of the forming speed on preventing the cracks and wrinkles in drawing. A finite element method (FEM) software package—ABAQUS®, is utilized to predict the distribution of displacement stress, strain of the work material in drawing. Crack (related to thinning behavior) and wrinkle are two indices of the drawing failure criteria in simulation. An optimal forming speed could be estimated by simulation. The optimal forming speed would cause the maximum limit drawing ratio which is beneficial to prevent drawing failure. The analytical results were verified experimentally. The results show that the predicted drawing speed was consistent with the real experiment and simulation.

Abstract:
The deep drawing process is widely used in industry because it allows the production of parts with reduced weight and good mechanical properties. However, the deep drawing process of non-cylindrical shapes still relies on experimental and trial and error methods, leading to high costs and long development times. The deformation mechanism of non-cylindrical cup drawing is theoretically very complex because of the large elasto-plastic stress and strain, and contact conditions between the tools and the sheet metal involved. In particular, several attempts have been tried in the past to perform theoretical and numerical analysis of rectangular cups. This paper presents an analysis of the allowable deep drawing height (DDH) of rectangular cups. The aim of this paper is twofold: 1) to analyze and estimate the allowable DDH of rectangular parts using theoretical, numerical (FEM) and experimental methods, and 2) identify the theoretical expression that predicts with the highest accuracy the allowable DDH of rectangular parts. A new theoretical expression for predicting this DDH is also proposed. To perform the study FEM is used together with the experimental data from industrial parts. The results show the accuracy of each theoretical expression in predicting the allowable DDH of rectangular parts.

Abstract:
Cylindrical hollow polymer fibers are drawn in an environment in which the heat transfer is approximately half radiative and half convective. A preform is introduced into the drawing furnace through an iris, travels vertically downward through the furnace, and fiber of reduced diameter exits through a bottom iris. For photonic crystal and biomedical applications one or more circular channels are drilled longitudinally in the preform. Challenges arise in the manufacture of hollow polymer fibers because the hole to outer diameter (aspect) ratio of the preform can change as the material is heated and drawn into fiber. Experiments to quantify the trends in aspect ratio changes have been performed. The results indicate that further study of the drawing process for hollow fiber is needed. Experiments with thick walled hollow fibers show poor repeatability even at stable drawing conditions, and the trends were not captured well by existing models. A simple 1-D model is presented and compared to the experimental results.

Abstract:
Abstract Electrically assisted manufacturing is the direct application of an electric current or field to a workpiece during a manufacturing operation. In addition to resistive heating, various anomalous effects have been observed experimentally. Since its conception in the 1950s, scientists continue to debate the existence of these so called electroplastic effects (EPEs) due to conflicted results shown throughout literature. A popular theory of electroplasticity is the electron wind, which postulates that there is a transfer of momentum between electrons and dislocations, which assists their motion during deformation. Though refuted both mathematically and experimentally in other types of tests, the electron wind theory, and therefore the existence of electroplasticity, is interestingly supported by the existence of polarity effects in wire drawing. A detailed review of the literature that has shown polarity effects in wire drawing is conducted. While the authors of these publications failed to fully disclose all test parameters, requiring several assumptions to be made, it appears that no mathematical/logical trends could be established. It is hypothesized herein that the velocity of the wire in a wire drawing application can influence the drift velocity of electrons, thereby increasing or decreasing current flow explicitly through the moving section of the wire. In order to test this hypothesis, a fixture was constructed which is capable of passing a current through a moving wire at common wire drawing speeds. Modern sensing equipment was used to measure various electrical parameters during testing. The wire speed effect hypothesis was refuted by experimental testing. While the results of experimental testing thus far indicate the existence of electroplasticity, further testing that includes drawing and force measurements must be conducted in order to fully conclude its existence in the wire drawing application.

Abstract:
Abstract Forming of tubes in various shapes has been a major interest in vehicle, instrumentation, decoration and precision industries. Due to a variety of shapes that can be achieved by tube forming, this manufacturing process has taken a major part in research and application. In this manufacturing process, a tube with a certain diameter and thickness can be considered to shape the part. The shaping or forming can be achieved by end forming, expanding the section, bending the section, buckling the tube, and/or reducing the section. Traditionally, to form these sections the rigid tool, flexible tool or fluid pressure would be needed to shape the tube. However, tools like mandrel or plug and their sizes limit the size of the tube to be formed. In this paper, tubes are formed by stretching them while simultaneously passing the direct current through. This process has been explored earlier by heating the tube using induction heating or rotary laser heating method. However, as no dies or tools are used to form these tubes, the process is considered dieless tube drawing which involves heating the tubes and drawing them into a reduced section. This study considers two different thicknesses but the same outer diameter tubes. The drawing force, shape, and microstructure are investigated. Based on the stress-strain curve, the yield to fracture and tensile to fracture strains are determined and discussed.
