Abstract of

GFPDII  System Manual

 

This document comprises of twelve chapters, provides an insight into the design of GITA FLAT PATTERN DEVELOPMENT (GFPD) SOFTWARE System, which could be utilized for the Flat Pattern Development of Sheet Metal Components. This software has been designed to handle simple, medium and complex aircraft components. It runs on PC in WINDOWS environment.

 

In the First chapter an introduction to the software and the CAD environments is provided.

 

Second chapter gives an overview of the aircraft sheet metal components, which could be either directly modeled in GIT A environment or brought onto this through translators. It also contains the nomenclatures of the terminologies.

 

The next two chapters bring out the classification of SMCs with wide variety features together with the features of SMCs addressed in this phase.

 

Fifth and sixth chapter contains design and analysis of various algorithms along with the macro commands developed for different methods of sectioning like radial, parallel and normal.

 

The seventh section gives the design and development of point transferring technique for FP development of Non FPS components and also new and unique relative assessment of various techniques developed and implemented.

 

Eighth chapter illustrates the Production features and the algorithm for processing Nibbled Holes.

 

The ninth chapter recapitulates the bend correction algorithm, implementation for Non FPS components with surface modeling options together with variety of material and geometric data sets.

 

The tenth chapter brings out the details on FPD for cone frustum and the eleventh chapter deals with PC based loft generation including CAD model transfer issues.

 

Chapter 12 lists out GITA CAD functions used in GFPD and the concluding section brings out the accomplishments, short comings and. future course of action.
