  11. 11. EMM 5704 Computer Applications in Manufacturing Systems By: Dr. Faieza AbdulEMM5704 Computer Applications in Manufacturing General Overview In this 21st century which is also know the century of speed. Mega manufacturers nowadays are competing to improve their services in fulfilling the markets demand globally. Virtual reality is a fast growing manufacturing application that has multiple advantages into pushing the advancement of manufacturing technology to a different level.
  12. 12. EMM 5704 Computer Applications in Manufacturing Systems By: Dr. Faieza AbdulEMM5704 Computer Applications in Manufacturing Why apply in Manufacturing? • to assist in minimizing human errors • shortening the research and development period • reduce the expenditures • and improve the designs reliability
  13. 13. EMM 5704 Computer Applications in Manufacturing Systems By: Dr. Faieza AbdulEMM5704 Computer Applications in Manufacturing CAD to Virtual Reality It is hard to decide which software to implement when designing for the purpose of applying virtual reality. Adapting the designing software and translate it to a language understood by the virtual reality hardware is the main consideration.
  14. 14. EMM 5704 Computer Applications in Manufacturing Systems By: Dr. Faieza AbdulEMM5704 Computer Applications in Manufacturing Language Translation Methods Basically, there are two ways of translating the design. Firstly, known as the direct translation which is directly translating the design from CAD to VR. And secondly, intermediate translation which is by using the aid of another software to translate CAD’s design into VR reality.

  16. 16. EMM 5704 Computer Applications in Manufacturing Systems By: Dr. Faieza AbdulEMM5704 Computer Applications in Manufacturing Why CAD • CAD is widely used to perform this task is because the price of the software is more reasonable compared to other designing softwares. • Other than that, it is one of the oldest designing software, hence, many expert designers that are capable of preparing complex software is familiar with it. • Furthermore, this tool is easy to use, and has the flexibility in performing complex designs. • And also, most education sectors provide the service in teaching design using CAD software.
  17. 17. EMM 5704 Computer Applications in Manufacturing Systems By: Dr. Faieza AbdulEMM5704 Computer Applications in Manufacturing The Application One of the top German car manufacturing companies (Volkswagen) has applied this function, the purpose was to implement new method for improving and accelerating the development process in vehicle styling and design. Three main steps were used to generate the complete virtual reality design.
  18. 18. EMM 5704 Computer Applications in Manufacturing Systems By: Dr. Faieza AbdulEMM5704 Computer Applications in Manufacturing How the System is Built.. Three main steps were used to generate the complete virtual reality design. Firstly, creating the design using AutoCAD.
  19. 19. EMM 5704 Computer Applications in Manufacturing Systems By: Dr. Faieza AbdulEMM5704 Computer Applications in Manufacturing Secondly, preparing the model, this step requires to change the design into meshes, the more meshes created the more detailed the design can be, and then the designer should work on eliminating the meshes and obtain a clean clear design
  20. 20. EMM 5704 Computer Applications in Manufacturing Systems By: Dr. Faieza AbdulEMM5704 Computer Applications in Manufacturing Thirdly, colours should be added to the design to vivifies the product and make it look real.

  27. 27. EMM 5704 Computer Applications in Manufacturing Systems By: Dr. Faieza AbdulEMM5704 Computer Applications in Manufacturing Disadvantages of AR o Three dimensional, real-time running augmented reality programs like "first person shooters" have been believed to increase teen aggression because they normalize violence. o The lack of privacy. o Difficult to maintain Augmented Reality Systems. o Augmented reality is leading to an era of no privacy, where criminals could simply point their phone at victims and learn anything they need to know about them.
  28. 28. EMM 5704 Computer Applications in Manufacturing Systems By: Dr. Faieza AbdulEMM5704 Computer Applications in Manufacturing • Google Glasses and Augmented ID or any other face detection application effect the privacy of humans.
  29. 29. EMM 5704 Computer Applications in Manufacturing Systems By: Dr. Faieza AbdulEMM5704 Computer Applications in Manufacturing The Future of Virtual Reality • Virtual Reality is a growing industry. • PC and specialized hardware are getting better, faster and cheaper because of development in VR. • Maybe 3D user interfaces will replace the windows based ones? • Huge demand for VRML programmers in near future. • Revolution in gaming industries.
  30. 30. EMM 5704 Computer Applications in Manufacturing Systems By: Dr. Faieza AbdulEMM5704 Computer Applications in Manufacturing Conclusion • With the help of virtual reality delicate operation had been carried out in the field of medicine. Military have been able to train in a way that physically it would not have been possible without the help of virtual reality. In manufacturing right from design and development virtual reality had help to come out with complex. Not only that maintenance had made simple because of virtual reality. In film industry most of the effect that we watch thinking is real they are just effect of virtual reality. Therefore VR has greatly enhances the design, product, delivery, storage. VR is virtually utilized in all works of life. But it does not mean that VR has no disadvantages.
  31. 31. EMM 5704 Computer Applications in Manufacturing Systems By: Dr. Faieza AbdulEMM5704 Computer Applications in Manufacturing Some aspects, such as the technology that is used, pose significant problems to developers and cause restrictions in attempts at widespread use and distribution. The Cost: This new technology is expensive. The cost of developing hardware and software for the application of virtual reality technology is too great for many institutions to implement at this time. Computer instrumentation is expensive after introduction but has always decreased over time; so I suspect as this occurs virtual reality will eventually become more commonplace in Medicine.
  32. 32. EMM 5704 Computer Applications in Manufacturing Systems By: Dr. Faieza AbdulEMM5704 Computer Applications in Manufacturing The Restraint: Presently the equipment used to create a virtual environment is restrictive and uncomfortable to its users. This would have to be overcome for more convenient uses in surgical procedures.
