To represent 3-D objects properly, several types of techniques have been developed in the field of solid modeling. Solid modeling techniques describe 3-D products and in recent year we have seen a growth by the rapid multiplication of solid modelers and 3-D CAD systems. The geometric elements of the solid model will be analyzed and features those are recognized as manufacturing entities will be extracted and organized according to topological manner. To detect manufacturing information from solid models produced by computer-aided design (CAD), feature recognition technique is used that focuses on the design and implementation of algorithms. Automatic feature recognition (AFR) technique is an important tool for achieving a true integration of design and manufacturing stages during the product development, and considered to be a critical component for integration of CAD and CAM. This paper is concerned with the overview of different feature recognition research focusing on four of the major feature recognition algorithmic approaches. Detailed description of algorithm for each approach will be presented along with some examples.
