Assembly Procedure

Assembly process sheets are formal documents used extensively within automotive original equipment manufacturers (OEMs) to document and communicate assembly procedure, required tooling, contingency plans, and time study results. These sheets are authored throughout the vehicle life-cycle. Further, various customers use these sheets for training, analyzing the process, and line-balancing. In this research, the primary focus is the time studies analysis that is completed using knowledge contained within the assembly process sheets. In this research, a method and software tool are developed to utilize coupling between part descriptions and process descriptions for assembly time studies. The method is realized through the development of a standardized vocabulary for describing work instructions, a mapping from work instructions to MTM codes, and a tool for extracting relevant part information from CAD models. The approach enables process planners to establish part-process coupling, author work instructions using the controlled vocabulary, to estimate assembly time. A prototype system is developed and tested using examples from an automotive OEM.

Abstract This paper summarizes the latest developments in robot-to-robot collaboration for fixtureless assembly. In addition, some of the technology challenges and potential applications in the automotive industry are described. Fixtureless assembly systems have been developed to increase the flexibility of body shop systems. These systems eliminate the need for using dedicated fixtures to set the geometry of body assemblies. A key technology enabler for a fixtureless assembly process is robot-to-robot collaboration based on perception and advanced control solutions. In a fixtureless assembly process, robots move and hold parts together in the geometry setting pose for assembly instead of using fixtures. In this paper the technology requirements and performance results of a production-relevant demonstration cell are presented. Moreover, the technology and performance requirements to use the fixtureless approach in other automotive assembly applications are reviewed. Results show that dimensional performance from the newly developed fixtureless process was acceptable and within the tolerance range. Initial cost estimate show that a fixtureless process offers a significant cost benefit over a conventional assembly process, especially for a multi-style production line or when new styles are frequently introduced.

Stamping Part

With the higher quality requirement of automotive assembly, the demand for forming precision of the stamping part gets higher. The simulation of resilience around the edge of drawn parts of autobody panels has become a hot spot of automotive field. Currently, the study on resilience mainly focused on the principle of resilience of bent parts and its relative control whereas the investigation on resilience of drawing process is quite less. This paper has studied the object of automobile cover panel through comparison of captured contour to calculate the resilience of edges of part, resolve the resilience problems of drawn part, for which the traditional calculation method and CAE software, focusing on bending resilience issues, couldn’t provide their solution.
