Applying automated methods to the building of brickwork houses means savings in both time and cost. In principle, two different methods compete with each other: “Robots on site” and “factory prefabrication of wall elements”. However, prefabrication has already proved its advantages with a number of different manufacturers, where robots on site have not yet succeeded beyond the prototype stage.
This article describes a new flexible computer program, for the planning and manufacturing of wall elements, incorporating CAD interface possibilities. The program developed is a completely object orientated Microsoft Windows application which adopts a modular concept, thereby allowing adaptation or inclusion of the modules to other applications. The existence of such a program is regarded as a very important requirement for masonry automation. 相似文献

Abstract: A CAD/CAM system that automates the design and manufacturing of rebars is described. The CAD-based design module of the system permits a semiautomated design alongside the conventional one. The uniqueness of the system resides in its ability to extract automatically the data needed for manufacturing from the graphic design database, process these data, and transfer them to the rebar-manufacturing machine. Thus all the manual data manipulation stages of traditional rebar design and production (detailing, documentation, data extraction, etc.) are avoided. In many cases the multistage manual data manipulation is a source of errors and is moreover labor-intensive. Consequently, the CAD/CAM system described here leads to cost reduction together with increased quality. This paper describes the principles underlying the development of the system and the system's structure, which is based on a design module, a data extraction module, and a data processing and transfer module. 相似文献
