This paper describes the research work involved in the development of an expert system for process planning of sheet metal parts produced on compound die. The proposed system is organized in six modules. For development of system modules, domain knowledge acquired from various sources of knowledge acquisition is refined and then framed in form of ‘IF-Then’ variety of production rules. System modules are coded in AutoLISP language and user interface is created using visual basic (VB) . The system is capable to automate various activities of process planning including blank modeling, blank nesting, determining punch force required, selection of clearance between punch and die, identifying sheet metal operations, and determining proper sequence of operations for manufacturing the part. The proposed system can be implemented on a PC having VB and AutoCAD software, therefore its low cost of implementation makes it affordable even for small scale sheet metal industries.  \nKeywords.

Introduction  \nCompound die is widely used in sheet metal industries for manufacturing of pierced blanks with good accuracy. Process planning of sheet metal parts is an important activity for the design of a compound die. An experienced die designer or process planner needs to perform various activities for process planning such as blank modeling, blank nesting, determining punch force required, selection of clearance between punch and die, identifying sheet metal operations, and determining proper sequence of operations for manufacturing the part. Traditional methods of carrying out these activities are tedious, time-consuming, skill-intensive, error-prone and largely based on the rich experience-based knowledge of domain experts [1] . A die designer needs to spend many hours consulting hand books, going through empirical formulae, perusing tabulated and graphical information, and making calculations before arriving at practical designs [2] . Further, nowadays sheet metal industries are also facing problems due to scarcity of  \n*For correspondence  \nexperienced die designers and their frequent mobility. Some researchers have applied efforts to develop computer aided systems for process planning of sheet metal parts. For example, Xiao et al [3] developed an expert system using a set of production rules and frames for process planning of axisymmetric deep drawing parts. The system is suited to the process planning of general drawing process and to the strip layout of progressive drawing of axisymmetric parts. Hoffmann et al [4] developed a bending-sequence generator using expert system approach to computerize the process-planning of sheet-metal parts. But planner’s interaction is still required. Fang and Tolouei-Rad [5] proposed a rule based expert system for process planning of complex circular shells produced by deep-drawing process. Jin et al [6] developed a knowledge based system (KBS) for design of tube bending","cbCairBs8UgNcA6H","https://ap.wps.com/l/cbCairBs8UgNcA6H","pdf",536995,"English","# 1. Introduction\n# 2.
