The STEP files of CAD models of gears have been used as input to the whole system. The algorithm is executed in two main stages. In the first stage, the spur and helical gears are identified by expert system by reasoning STEP physical file of CAD model belonging to any gear and rules represented in a knowledge base constructed for the expert system. In the second stage, detailed dimensions of the identified gears are extracted via data obtained from STEP file. Although the developed approach is only applied to spur and helical gears in this study, it can be successfully implemented to different part families such as bolts, nuts, washers, pipes etc. for other CAD/CAM applications.trinfo:eu-repo/semantics/closedAccessSpur and helical gearsexpert systemSTEP3D solid modelArticle233709717N/A
