AMRF Database Report Format: Part Model



Ted Hopp


Many systems in the NBS Automated Manufacturing Research Facility (AMRF) need to manipulate part model data. Some systems, such as Design and Process Planning, must generate new models, access existing models, and update existing models. Other systems, such as the Cleaning and Deburring Workstation, only require access to existing models. Sharing of part model data is supported in the AMRF by the AMRF distributed data management system (IMDAS). Part models are stored in databases integrated with the IMDAS architecture, and these models are accessed by the application processes via queries through IMDAS. In the current architecture, a query concerning a part model, whether the query is an insert, delete, select, or update, always has an associated file containing the part model data. In the AMRF terminology, a data file associated with a query is termed a Database Report. This document specifies the format of part model database reports as used in the AMRF.
