Smart System for Feature Recognition of Sheet Metal Parts: A Review

Sheet metal is one of the most frequently used primary manufacturing methods to produce different variety (shape and size) of components. The production of these sheet metal parts with a product (design) features is a major task in the sheet metal industries. Feature recognition is a primary activity for design of dies. Usually, this task is performed by experienced process planner in industries. The present review gives an overview of computer-aided smart system for feature recognition of sheet metal parts. The proposed system is capable to extract/recognize all design features of sheet metal parts automatically from 3D CAD model. The system has been implemented in AutoCAD using AutoLISP programming language.
