TL;DR: This paper presents a research effort aimed at creating a virtual assembly design environment that combines 3D computer graphics with advanced input and output devices for design for assembly.
Abstract: Virtual reality is a technology which is often regarded as a natural extension to 3D computer graphics with advanced input and output devices. This technology has only recently matured enough to warrant serious engineering applications. The integration of this new technology with software systems for engineering, design, and manufacturing will provide a new boost to the field of computer-aided engineering. One aspect of design and manufacturing which may be significantly affected by virtual reality is design for assembly. This paper presents a research effort aimed at creating a virtual assembly design environment.
TL;DR: A review of the research in virtual assembly is provided and the potential to support integration of natural human motions into the computer aided assembly planning environment and results in reduced time and cost for product design are presented.
Abstract: Assembly planning and evaluation is an important component of the product design process in which details about how parts of a new product will be put together are formalized. A well designed assembly process should take into account various factors such as optimum assembly time and sequence, tooling and fixture requirements, ergonomics, operator safety, and accessibility, among others. Existing computer-based tools to support virtual assembly either concentrate solely on representation of the geometry of parts and fixtures and evaluation of clearances and tolerances or use simulated human mannequins to approximate human interaction in the assembly process. Virtual reality technology has the potential to support integration of natural human motions into the computer aided assembly planning environment (Ritchie et al. in Proc I MECH E Part B J Eng 213(5):461–474, 1999). This would allow evaluations of an assembler’s ability to manipulate and assemble parts and result in reduced time and cost for product design. This paper provides a review of the research in virtual assembly and categorizes the different approaches. Finally, critical requirements and directions for future research are presented.
TL;DR: A novel interaction metaphor is presented that facilitates the synthesis of efficient virtual reality interaction and visualization techniques with modern feature based CAD systems and an alternative approach for navigation, manipulation and selection is presented.
Abstract: Current virtual reality (VR) systems provide an enormous potential for enhancing the visualization of 3D-design drafts. Based on new navigation techniques the designer is able to interact, model in a more intuitive and efficient way. In our contribution we present a novel interaction metaphor that facilitates the synthesis of efficient virtual reality interaction and visualization techniques with modern feature based CAD systems. We present “NAVIMODE”, an alternative approach for navigation, manipulation and selection, to combine the advantages of VR and CAD systems. The design engineer has the chance to design in his/her habitual environment using the advantage of virtual reality concurrently.
