CAD in a Community
The product lifecycle is generally divided up into sections: Beginning-Of-Life (BOL), Middle-Of-Life (MOL) and End-Of-Life (EOL). The traditional notion of product development has concerned a simple CAD-CAPP-CAM-CNC chain at the beginning of life. This needs to be updated, though, to fit new theory and practice. The Middle-Of-Life, or “Use phase” is where data about component behaviour can be recorded and stored. At the End-Of-Life this data can be collected to see if a component can be reused. Data about the product at the end of life is also important to help designers make improvements.
