Spatial augmented reality on industrial CNC-machines

The Engineering Reality of Virtual Reality 2008, 2008

In this work we present how Augmented Reality (AR) can be used to create an intimate integration of process data with the workspace of an industrial CNC (computer numerical control) machine. AR allows us to combine interactive computer graphics with real objects in a physical environment -in this case, the workspace of an industrial lathe. ASTOR is an autostereoscopic optical see-through spatial AR system, which provides real-time 3D visual feedback without the need for user-worn equipment, such as head-mounted displays or sensors for tracking. The use of a transparent holographic optical element, overlaid onto the safety glass, allows the system to simultaneously provide bright imagery and clear visibility of the tool and workpiece. The system makes it possible to enhance visibility of occluded tools as well as to visualize real-time data from the process in the 3D space. The graphics are geometrically registered with the workspace and provide an intuitive representation of the process, amplifying the user's understanding and simplifying machine operation.

The paper presents the application of augmented reality to support product design and development. The paper concentrates on a new engineering tool. By this reason design and its issues are presented in a very limited way. The goal of the research was to improve design process and reduce product development time. The presented system bases on CAD software which is integrated with an expert system and augmented reality techniques as a human-computer communication interface. The authors present possibilities of using augmented reality technology in CAD design with the hope that maybe someday it would become integral part of a standard design process of more reliable and durable machinery systems.

This paper describes results of the research concerning an augmented reality (AR) system for CAD design, developed within the framework of MSc Thesis in the Department of Fundamentals of Machinery Design. The authors present advantages resulted from utilization of AR systems allowing to combine the interactive computer-generated world with an interactive real world in such a way that they appear as one environment, especially in CAD design. The authors decided to apply the system to aid the designer of the machinery systems by choosing standard parts. The system enables the user to easily view the 3D models of standard parts from any perspective, in more natural, intuitive way than traditional one (on the computer screen). Next, the user can export the model to the modeling software and use it to model some machinery system. This paper presents possibilities of using AR technology in CAD design with the hope that maybe someday it would become an integral part of a standard design pr...

In many domains where VR has proven its value, augmented reality (AR) starts getting recognition as a viable alternative to its more mature predecessor. Unfortunately, it has been suffering from similar challenges that VR needed to overcome. Some application domains, e.g. manufacturing, pose additional barriers preventing AR for widespread. So far in manufacturing, AR applications have been built with a specific task in mind and were mostly prototypes. In this paper, we focus on an AR application for process control with an emphasis on a generic process structure. This approach would allow to reuse the AR application in a range of processes which could be easily defined by a limited number of parameters. To test this approach, we developed an AR application using off-the-shelf components and applied it to a machining process in an actual manufacturing center. We used up to thirteen parameters to define each step of the process and provide input to the algorithm driving the AR applic...

The paper presents the application of augmented reality for aiding product design and development of machinery systems. Augmented reality technology integrates an interactive computer-generated word with an interactive real word in such a way that they appear as one environment. AR technology can enhance a user's perception of the real world with information that is not actually part of the scene but is relevant to the user's present activity. Presented in the AR system is a mode for changing views of data-especially 3D models-allowing the user to understand the prospective machinery system in a more comprehensive way, thus making the design process more efficient than the one supported by conventional present-day CAD systems. The presented prototype system contains an expert system integrated with AR system and allows the delivering of knowledge to the designer about successive steps of the design process of a mobile robot and practical solutions of realized constructional problems. An approach concerning AR enables the system user to analyze and verify solutions (represented as 3D models) relative to real scenes/objects. This approach is advantageous because the real environment around us often provides a vast amount of information that is difficult to duplicate in a computer. In some cases, the application of an AR system could be an optimal way to verify developed products.

Augmented Reality (AR) is a novel technology that projects virtual information on the real world environment. With the increased use of Industry 4.0 technologies in manufacturing, AR has gained momentum across various stages of product life cycle. AR can benefit production operators in many manufacturing tasks such as quality inspection, work instructions for manual assembly, maintenance, and in training. This research presents not only a typical architecture of an AR system but also both its software and hardware functions. The architecture is then applied to display virtual assembly instructions in the form of 3D animations on to the real world environment. The chosen assembly task in this research is to assemble a planetary gearbox system. The assembly instructions are displayed on a mobile device targeting a static tracker placed in the assembly environment

This paper describes a study of the potential of using augmented reality at the industrial shop-floor with the aim of improving the capability of the shop-floor operators. In the study, a prototype system for augmented reality is developed based on the Oculus Rift platform. The system is evaluated through an experiment in which a physical three-dimensional puzzle is to be assembled.

The paper presents the results of a research on applications of Augmented Reality (AR for short) which have been carried out in the Department of Fundamentals of Machinery Design, Silesian University of Technology, Gliwice, Poland. AR is a technology rising from Virtual Reality (VR). Generally, the main aim of application of AR technology is to aid the user in his/her operation in the real world. There are briefly described the applications of augmented reality concerning three important stages of a product lifecycle. The first one is the implementation of AR in machinery designing. The second one concerns aiding a technician in his maintenance work. And the last one is the application of AR in machinery diagnostics.

Francisco de Paula Santander Ocaña University has a botanic garden. The University Botanic Garden Jorge Enrique Quintero Arenas was created with the mission of preserving the dry forest ecosystem and the types of vegetation and flora present in the northeast of Colombia, providing adequate spaces for research and environmental education. From new technologies that can be integrated without affecting the environment and generate various changes in the way of learning, solutions are proposed for continuous improvement, which in the end is done in favor of sustainability, quality of life and a smart botanic garden. This paper presents the results of the software prototype, whose purpose is to make known all the biodiversity that is available. It was done through a digital album applying augmented reality, where those interested will find the different species with their relevant information.
