In Part 1 of this two-part paper, we review the development of open architecture controllers for machine tools. General design principles are described, followed by specific hardware and, software recommendations. These specific recommendations are then used for the construction of an open architecture device, MOSAIC-PM, (Machine tool Open System Advanced Intelligent Controller for Precision Machining). The machine has now been used in a wide variety of experiments to demonstrate open architecture control. These experiments include sensor based machining, rapid prototyping and manufacturing over the Internet. In Part 1, a specific application on feature based precision machining with on-machine acceptance is described. A more specific implementation of a quintic spline interpolation method is described in Part 2.

CNC machine tools are currently predominating in the machine-building industry. Generally, these machine tools are equipped with control systems supplied by the world's leading manufacturers, such as Siemens, Fanuc or HeidenHein, and are very expensive. In parallel, many cheap amateur and semi-professional CNC machine tool solutions are being developed. Below, a CNC milling machine of welded construction is described, which is intended to be, at the same time, a test stand. The design of the milling machine is based on steel closed sections of a large cross-section and a big wall thickness. This has allowed a rigid frame structure to be obtained. To obtain high displacement accuracy, high-accuracy profiled rail slideways have been used, along which pre-stressed linear ball bearings move. The machine tool has been furnished with a fourth numerically controlled axis, which is demountable.

The modular design system has recently become important, not only to rationalize the design and manufacturing procedures of the machine tool, but also to evolve the flexible manufacturing system. In this paper, therefore, to establish a design methodology for the modular construction system of machine tools, a generating method for structural configuration, i.e., a procedure of computer aided concept design has been proposed. The proposed method is of variant design type, in which a machine tool as a whole and modular complex are represented with the directed graph, it being suitable for the information processing and storage of data. When generating a structural configuration, at first, possible modular complexes in the data memory are referred to, and then through simple mathematical treatment they are integrated so as to form structural configurations. By this method, all possible structural configurations of the machine tool can be generated systematically and rationally, according to the machining requirement.

Machine tools are built based on cast-iron bodies. Cast iron well dumps down vibrations and is dimensionally stable. Therefore, many conventional machine tools are modernized and modified into CNC machine tools based on the seasoned old bodies of those machine tools. Nevertheless, CNC machine tools are also manufactured based on polymer concrete, which vibration damping ability is even better. On the other hand, attempts made in the past by leading machine tool manufacturers to use welded frames in CNC machine tools failed. The revival of interest in welded frames was spurred by economic considerations, as steel systems are much thinner compared to cast-iron ones. They are able to carry the same loads. The construction of CNC machine tools with a welded steel frame undertaken at the Institute of Mechanical Technologies (ITM) of the Czestochowa University of Technology is an attempt to solve this constructional problem. The machine tool frame was designed with use of CAD solid works system. The ultimate success of using the welded frame is determined not only by the frame itself, but also generally the design of the machine tool and its operation parameters. The welded frame was used for a high-accuracy three-axis milling machine. In this respect, it is equal of professional machine tools manufactured by reputed companies. It can be either a production machine tool or a test stand.

The marriage of computer, electronic technology and traditional machining disciplines has given birth to revolutionary new disciplines, Mechatronics. Therefore Mechatronics requires mechanical, electronic and computer knowledge together. The main aim of this article is to present the mechatronics approach for desk-top CNC milling machine design. Construction of computer controlled (CNC) Machine differs greatly from that of conventional machine tools. This difference arises from the requirement of higher performance levels. Machine Structure, guide ways, feed drives, spindle and spindle bearings, measuring systems, machine control unit, software and operator interface, gauging and tool monitoring should be considered as mechatronics approach. Servo motors, motor drivers and motor control unit were used in this CNC milling machine to make it flexible and easy programming. Ball screws were used to X-Y –Z axes to eliminate backlash of the slides. Non-contact home and Limit switches were used to prevent possible damages against over travels. Necessary torque and power have been calculated to select the motors by taking care of the load, ball screws, motor inertia and required cutting tools and etc. and developed CNC milling machine has been tested several times for reliable machining of machine parts.

In this paper, the problem of constructing geometric models from data provided by 3-D imaging sensors is addressed. Such techniques allow for rapid modeling of sculptured free-form shapes and generation of geometric models for existing parts. In order for a complete data set to be obtained, multiple images, each from a different viewpoint, have to be merged. A technique stemming from the Iterative Closest Point (ICP) method for estimating the relative transformations among the viewpoints is developed. Computational solutions are provided for estimating shape from noisy sensory measurements using representations that conform with commonly used representations from Computer Aided Geometric Design (CAGD). In particular, NURBS and triangular surface representations are applied in shape estimation. The surface approximations are refined by the algorithms to meet a user-defined tolerance value.

In this research, the authors have tried to decrease the weight of circular-digging large size bucket as far as possible with keeping the reliability of whole of the construction machine. In the case of main bucket, the authors have evaluated the strength reliability of this bucket and proposed more optimum design changing the thickness and kind of the material, though the expected weight reduction ratio becomes only 5% with increasing the rigidity of the main bucket. In the case of sub-bucket, it is desirable to change the thickness of the material and to attach the reinforcement in the both side. Therefore, the designer could reduce the weight by 11% with keeping the rigidity of the sub-bucket.

Handicraft of bamboo weaving has been a tradition that has been inherited for a long time, by using bamboo strips to weave into shapes to make tools and appliances. The bamboo strips are from dividing the longitudinal bamboo trunks into thin strips. In which most farmers will make the strips by hand by using a big knife or sharp objects. As a result, it takes a long time to prepare the bamboo strips to be used in the weaving work. There is also a risk of accidents from the use of sharp objects, including the size of the bamboo strips that is not the same size. This research aims to design and construct bamboo strips by dividing the research into 2 steps: 1) designing and constructing bamboo strips and 2) testing the operation of the stripping machine. The designed machine can be easily moved because it is a small and lightweight machine which is designed using a single-phase electric motor with a voltage of 220 volts, 250 watts, etc. Power to drive the roller through the transmission belt to convey bamboo parts through two 7-degree sets of blades with sharp angles that are placed horizontally. The first blade acts to separate the bamboo parts with the bamboo strips and the second blade acts to sharpen the bamboo strips. The results of the working test of the stripping machine by adjusting the blade angle at 1 and the level into 4 values that are 3, 4, 5, and 6 degrees, it was found that the machine was able to produce bamboo strips in size 1.47, 1.20, 1.97 and 2.27 mm, respectively. The size of the punching line is suitable for weaving containers such as round bamboo basket, wicker basket, and bamboo basket, etc.

Static and dynamic properties of machine tools have a decisive influence on their accuracy. In case of HSM machine tools, the phenomena associated with them are additionally strengthened by high machining parameters. In order to predict a machine tool behaviour at the design stage, it is necessary to use numerical methods to simulate for its simulation. Thanks to the use of this type of software, it is possible to perform the next step, i.e. the optimisation of the structure. In case of machine tools, due to the multiplicity of factors affecting its accuracy, this should be a multicriterial optimisation. This article presents the results of a vertical milling centre spindle body optimisation using the Finite Element Method. The results of static stiffness and vibration frequency analysis for three bodies (i.e. the body of the form and dimensions proposed by the constructor, the body after parametric optimisation and the body after the form and parametric optimisation including use of different materials) were compared. The optimisation tools available in the ANSYS system were used for the simulation. The calculations were preceded by experimental research and modifications of dynamic parameters performed on their basis using the author's methodology to determine the behaviour of a partially existing structure for different masses of the body being optimised.

Machine tool rams are important constructional elements found on vertical lathes as well as on many other machines. In most cases, a machine tool ram constitutes an assembly with significant dynamic compliance that affects the machine’s ability to achieve stable cutting conditions. There are various solutions for increasing a machine tool ram’s stiffness and damping. This paper describes an innovative concept of a two-axial electromagnetic actuator for controlled vibration dampers with high dynamic force values. The described solution is purposefully based on the use of standard electric drives. As a result, the size of the actuator is easier to scale to the required application. The solution is designed as a spacer between the end of the ram and the head. The paper presents the actuator concept, construction design, current control loop solution and experimental verification of the controlled vibration damper’s function on the test ram in detail. The presented position measurement concept will enable the use of non-contact position sensors for motor commutation as well as for possible use in vibration suppression control. Applications can be expected mainly in the field of vibration suppression of vertical rams of large machine tools.

A methodology is proposed for designing performance optimized computer systems. The methodology uses software tools created for performance monitoring and evaluation of parallel programs, replacing actual hardware with a simulator modeling the hardware under development. We claim that a software environment can help hardware designers to make decisions on the architectural design level. A simulator executes real programs and provides access to performance monitors from user's code. The performance monitoring system collects data traces when running the simulator and the performance analysis module extracts performance data of interest, that are later displayed with visualization tools. Key features of our methodology are "plug and play" simulation and modeling hardware/software interaction during the process of hardware design. The ability to use different simulators gives the user flexibility to configure the system for the required functionality, accuracy and simulation performance. Evaluation of hardware performance based on results obtained by modeling hardware/software interaction is crucial for designing performance optimized computer systems. We have developed a software system, based on our design methodology, for performance evaluation of multicomputer interconnection networks. The system, called the Parsim Common Environment (PCE), consists of an instrumented network simulator that executes assembly language instructions, and performance analysis and visualization modules. Using PCE we have investigated a specific network design example. The system helped us spot performance problems, explain why they happened and find the ways to solve them. The obtained results agreed with observations presented in the literature, hence validating our design methodology and the correctness of the software performance evaluation system for hardware designs. Using software tools a designer can easily check different design options and evaluate the obtained performance results without the overhead of building expensive prototypes. With our system, data analysis that required 10 man-hours to complete manually took just a couple of seconds on a Sparc-4 workstation. Without experimentation with the simulator and the performance evaluation environment one might build an expensive hardware prototype, expecting improved performance, and then be disappointed with poorer results than expected. Our tools help designers spot and solve performance problems at early stages of the hardware design process.

Mestrado em Engenharia Mecânica
Single Point Incremental Forming is a recent technology that is currently under development. Its applicability is diverse because it allows the attainment of functional parts in sheet metal without great costs. Due to this characteristic, areas such as biomechanics, rapid prototyping and products of customizable features make this process a target of interest. Unfortunately, the means of obtaining parts using single point incremental forming are limited. Usually, CNC machining centers are utilized but due to their cutting-type characteristics, the implementation of the Single Point Incremental Forming is limited and inefficient. Also, the market supply of dedicated machinery requires high investments, thus becoming an unattractive solution. A major obstacle to the application of this technique focuses on the superior time of forming especially when compared to conventional forming techniques. Another disadvantage of this process is the low dimensional accuracy, however, with the development of numerical studies and correction algorithms this problem tends to be minimized. This work aims to complete the project of a single point incremental forming machine that began in previous years. This project has the objective of overcoming the limitations of the current incremental forming machines, but not ignoring the economic factor. Also, this project aims to enlarge the horizons for future research and development of the process, not only improving the machine but also developing and understanding the forming mechanism and the consequent effects of improved material formability.
A estampagem incremental é um processo recente que está em desenvolvimento. A sua aplicabilidade é variada pois permite a obtenção de peças funcionais em chapa metálica sem grandes custos associados. Devido a esta característica, áreas como a biomecânica, prototipagem rápida e produtos de características personalizáveis fazem deste processo um alvo de interesse. Infelizmente, os meios de obtenção de peças usando estampagem incremental por ponto único são limitados. Normalmente faz-se uso de centros de maquinagem CNC adaptados, que devido às suas características próprias de corte por arranque de apara, tornam a aplicação da estampagem incremental limitada e ineficiente. Além disso, a oferta de mercado em maquinaria com características dedicadas ao uso de estampagem incremental requerem elevados investimentos, tornando-se assim uma solução pouco atractiva. Um dos principais obstáculos à aplicação desta técnica centra-se no tempo de conformação elevado, principalmente quando comparado com técnicas de estampagem convencionais. Outra desvantagem deste processo é a baixa precisão dimensional, que todavia com o avanço dos estudos numéricos e com o desenvolvimento de algoritmos de correcção tende a ser minimizado. Neste trabalho pretende-se concluir o projecto de uma máquina para realização de estampagem incremental por ponto único que teve início em anos anteriores. Este projecto tem por objectivo a obtenção de uma máquina que ultrapasse as limitações das máquinas actuais, mas não desconsiderando o factor económico. Além disso este projecto visa ampliar os horizontes para futuras pesquisas e desenvolvimento do processo, tanto na melhoria da máquina, mas também no desenvolvimento e na compreensão do mecanismo de deformação existente e aumento associado da formabilidade material.

Thesis (DTech (Mechanical Engineering))--Cape Peninsula University of Technology, 2015.
This dissertation addresses the development and the testing of a simulation tool to be used to predict the behaviour of smart material/structures. Along with the development of the simulation tool, a new form of the model describing the behaviour of shape-memory alloy was developed and implemented. The proposed model was developed based on the existing cosine model, conventionally used in literature, but it uses hyperbolic tangent functions. The hyperbolic tangent function was chosen so as to allow the simulation of any range of temperatures. Experiments were performed to obtain the parameters to be used in the simulation and to validate the numerical results. Two different simulations were performed: a one dimensional FEA analysis with a two dimensional orientation (NiTi SMA wire simulation) and a three dimensional FEA analysis (NiTi SMA plate) [Msomi and Oliver, 2015]. Alongside the FEA analysis, two experiments were performed with the purpose of obtaining the material parameters to be used in FEA analysis and to compare the FEA results to the experimental results.

Recent years has seen a significant drive away from traditional procurement routes with contractors finding themselves with an increasing responsibility for control of design - a process they have had little experience in managing. They now have to adapt accordingly. The learning curve is steep, not least because many projects must now be delivered fast track while co-ordinating increasingly complex fabric and content of buildings without a platform of accepted good practice to manage the design process. This is a major factor preventing the UK construction industry from delivering projects on time, to budget and to the specified quality. There is a need to educate an increasing number of people in design management techniques to equip them to manage today's fast moving and demanding projects. However, many current design management tools are insufficiently developed for industry application. Therefore, to improve design management in the industry, current techniques must be modified to align them with the needs of the modern design manager. This research has developed and tested a training initiative aimed at improving design management practice within a major UK Design and Construct Contractor. It comprises a Design Management Handbook, Design Management Training, Team Support and Project Monitoring. The Design Management Handbook is the core of the training initiative. It addresses critical aspects of design management practice and provides design management tools. Training provides guidance to project teams on the tools and practices. In Team Support project teams are supported in the implementation of the new practices and tools to help embed new ways of working in company practice. Project Monitoring establishes the impact of the new practices on project performance to demonstrate that they are working and thus reinforce change. To establish the training initiative's effectiveness and key findings, the impact of the initiative on design management performance has been explored. The research has established which practices and tools were used, which were not, as well as an understanding the applicability and performance of each Handbook practice and tool. From this, barriers to implementing new design management tools in industry were identified and strategies developed in order to overcome such barriers.

This thesis is concerned with the development of virtual Human-Machine Interfaces (HMI) and navigation method for wheelchair systems. For virtual HMI, hand gesture recognition is employed, and two different hand gesture recognition algorithms have been developed. One is based on the geometric properties of a hand shape, and the other algorithm is based on the curvature of a hand shape contour. In the hand gesture recognition algorithm using geometric properties of a hand shape, eight non-dimensional parameters are computed and identifies hand shapes by comparing the ranges of the parameters to the statistical range information. This algorithm is invariant at scale, but does not work properly if the forearm of a hand shape is cluttered. The curvature based hand gesture recognition algorithm recognizes hand gestures using a combination of hand shape contour geometry and a non-dimensional quantity derived using the curvatures of the hand shape contour. The algorithm produces a set of signatures of the contour and identifies each hand gesture by finding matched template signatures. This algorithm is not affected by the forearm of a hand shape, but the scaling procedure is required. The developed gesture recognition system is implemented on a wheelchair in two different modes of operations, namely, the manual mode and the map (autonomous) mode. In the manual mode, the user continuously interacts with the wheelchair and controls the speed and the steering using the position and the orientation of hand gestures. In the map mode, the user selects a desired destination by pointing with a hand gesture onto a known map, and then the wheelchair initiates autonomous navigation. For wheelchair navigation, a doorway recognition algorithm and an obstacle avoidance algorithm have been developed. The wheelchair is localised by finding the doorway template in the specified zone. If the doorway recognition algorithm does not detect the doorway, it navigates to find the doorway using the obstacle avoidance algorithm. The obstacle avoidance algorithm finds obstacle edge points using range data and decides a safe passage for wheelchair navigation to find the doorway. Results obtained by implementing the above mentioned algorithms are presented.

Growing energy demand in the world force people to investigate alternative energy sources. Unlike coal or other fossil fuels, renewable energy sources are promising for the future. Especially, seed oils are effectively used as energy sources such as fuel for diesel engines. The scope of this study is to develop an oil extraction machine specific to canola seed. In this study, seed oil extraction methods have been investigated and various alternatives for the extraction machine have been considered. For continuous operation, oil extraction with a screw press is evaluated as the most appropriate solution. Four different prototypes have been designed and manufactured. According to the results of testing of prototypes, they have been modified and gradually improved to increase oil extraction efficiency. The working principle of the selected screw press based on the rotation of a tapered screw shaft mounted inside a grooved vessel. The screw shaft is a single square-threaded power screw having an increasing root diameter from inlet to exit while the outside diameter of the screw shaft is 66 mm. Seeds are taken into the system at the point where the depth of the screw thread is maximum. Then they are pushed forward by the threads on the rotating screw shaft and pass through inside the vessel. So, the fed seeds are compressed as they move to the other side of the vessel. Recovered oil escapes from high pressure zone and drains back. The oil is drained out from the oil drainage holes that are machined on high pressure zone of the vessel. Besides, the cake is extruded at the end of the vessel and the screw shaft. The cake thickness is adjustable by the axial movement of the screw shaft. By adjusting the cake thickness, different pressures can be obtained. During the experiments, it is observed that four main features affect the oil recovery rate. These are the geometry of the grooves inside the vessel, the taper angle of the screw shaft, the operating temperature and the rotational speed. With the final prototype, an oil recovery efficiency of 62.5% has been achieved at 40 rpm with 15 kg/h seed capacity. Since the oil content of the seed is taken as 40%, oil recovery rate of the developed oil extraction machine is 3.75 kg/h. This efficiency is determined for a 0.8 mm cake thickness at 1.1 kW motor ower.

Abstract This paper describes a methodology used in the design of manufacturing machines to minimize life cycle cost. Life cycle costs include design, construction, installation, planned maintenance, repair, disposal and lost production caused by breakdowns. Studies have suggested that maintenance accounts for half of life cycle cost, and the primary focus of this methodology is to reduce repair and maintenance costs. This methodology has on average resulted in a 10 percent savings in capital investment, a 50 percent reduction in lifetime maintenance costs and a significant improvement in up-time.

Improving design methodologies and assessment tools for building on permafrost in a warming climate.

The U.S. Department of Defense (DoD) operates numerous Arctic and Subarctic installations, including Alaska. Changes to permafrost can threaten critical built infrastructure. It is critical to accurately characterize and compare site conditions in permafrost regions to enable the efficient, cost-effective design and construction of an infrastructure well suited to the permafrost environment and that meets DoD requirements. This report describes three research efforts to establish (1) field investigation approaches for ground ice detection and delineation, (2) methods and modeling for early warning detection of thawing permafrost under infrastructure, and (3) an outline of a decision support system that determines the most applicable foundation design for warming and degrading permafrost. Outcomes of these interrelated efforts address needs to improve construction of DoD mission critical infrastructure on Arctic and Subarctic permafrost terrains. Field investigation processes used systematic methodologies including borehole data and geophysical measurements to effectively characterize subsurface permafrost information. The Permafrost Foundation Decision Support System (PFFDSS) tool implements and logically links field survey information and foundation type assessments. The current version of PFFDSS is designed to be accessible to design-engineers of a broad range of experience, that will reduce the effort and cost, and improve the effectiveness of site assessment.

Intraspecies identification (DNA "fingerprinting") of pathogenic avian mycoplasmas is a powerful tool for epidemiological studies and monitoring strain identity. However the only widely method available for Mycoplasma gallisepticum (MG) and M. synoviae (MS)wasrandom amplified polymorphic DNA (RAPD). This project aimed to develop alternative and supplementary typing methods that will overcome the major constraints of RAPD, such as the need for isolation of the organism in pure culture and the lack of reproducibility intrinsic in the method. Our strategy focussed on recognition of molecular markers enabling identification of MG and MS vaccine strains and, by extension, pathogenic potential of field isolates. Our first aim was to develop PCR-based systems which will allow amplification of specific targeted genes directly from clinical material. For this purpose we evaluated the degree of intraspecies heterogeneity in genes encoding variable surface antigens uniquely found in MG all of which are putative pathogenicity factors. Phylogenic analysis of targeted sequences of selected genes (pvpA, gapA, mgc2, and lp) was employed to determine the relationship among MG strains.. This method, designated gene targeted sequencing (GTS), was successfully employed to identify strains and to establish epidemiologically-linked strain clusters. Diagnostic PCR tests were designed and validated for each of the target genes, allowing amplification of specific nucleotide sequences from clinical samples. An mgc2-PCR-RFLP test was designed for rapid differential diagnosis of MG vaccine strains in Israel. Addressing other project goals, we used transposon mutagenesis and in vivo and in vitro models for pathogenicity to correlated specific changes in target genes with biological properties that may impact the course of infection. An innovative method for specific detection and typing of MS strains was based on the hemagglutinin-encoding gene vlhA, uniquely found in this species. In parallel, we evaluated the application of amplified fragment length polymorphism (AFLP) in avian mycoplasmas. AFLP is a highly discriminatory method that scans the entire genome using infrequent restriction site PCR. As a first step the method was found to be highly correlated with other DNA typing methods for MG species and strain differentiation. The method is highly reproducible and relatively rapid, although it is necessary to isolate the strain to be tested. Both AFLP and GTS are readily to amenable to computer-assisted analysis of similarity and construction of a data-base resource. The availability of improved and diverse tools will help realize the full potential of molecular typing of avian mycoplasmas as an integral and essential part of mycoplasma control programs.
