In making the layout for this cleat the following points must be kept in mind. How to dimension a drawing. Just before the punch contact work 2. Drawing force power and number of stages defects in products.

A bend table lists propertied of all bends in a flat pattern view of a sheet metal part. Bend tags associate rows in a bend table with the view geometry. Bend notes are associated with a drawing view. However in order to have a measure for sake of comparison the limit drawing ratio ldr is taken as a measure of drawability.

Engineering graphics is used in the design process for visualization communication and documentation. The sheet metal cleat the work of this problem will consist in laying out to full size the views and pattern for a galvanized sheet metal cleat. Unit iv sheet metal working economical considerations stamping forming and other cold working processes. Cutting of sheet metal is accomplished by a shearing action between two sharp edges.
