Design and manufacturing of lime kiln:A Historical Perspecti
Desing and manufacturing are the core activities for realizing a marketbale and profitable product.A numberof ceolutionary changes have taken place over the past couple of the decades in the areas of both design and manufacturing .First we explor the developments in what is called CAD.The major focus in CAD technology development has been on latter representation completeness .Fig,1.2 show the evolutiong of the mechanical development of a two-dimensional drafting system in the 1960s,the che wxtension of 2D drafting system to three -dimensional models led to the development of wire-frame-based modeling systems.However ,it was not possbile to represent higher order geometry data such as surface data. To bridge this gap, surface models were decelopment.
