Abstract

The automated computer-aided drafting technique is attempted for drawing process pictures of axisymmetric solid forgings which are mainly used in automobile industry. For this study basic concepts to draw the shape of an element are described and applied to the 2-dimensional and 3-dimensional modeling of forged parts. 2-dimensional display of process pictures is developed by using AutoLISP language in AutoCAD software of a drafting technique and 3-dimensional view of process pictures is based on the UG/open API and UG/open GRIP languages of Unigraphics software. Testing the developed program to forging of bolts and ballstuds, it was shown to give good results to be applicable in forging industry.
