Just before the punch contact work 2. A bend table lists propertied of all bends in a flat pattern view of a sheet metal part. Bend annotations a bend note adds fabricating information to sheet metal bend centerlines. The shearing action is illustrated in the figure.

Blanking and piercing bending and forming drawing and its types cup drawing and tube drawing coining hot and cold spinning. Unit iv sheet metal working economical considerations stamping forming and other cold working processes. In making the layout for this cleat the following points must be kept in mind. Cutting of sheet metal is accomplished by a shearing action between two sharp edges.

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. Accuracy in the use of the scale rule. Drawing force power and number of stages defects in products. Formability of sheet metal is the ability of sheet metal to be drawn into cups or formed into the desired shapes without any defect.

The proper relation of views in a drawing. Punch begins to push into work causing plastic deformation 3. Engineering drawing basic sheet layout title block notes engineering working drawings basics. Bend tags associate rows in a bend table with the view geometry.

Engineering graphics is used in the design process for visualization communication and documentation. Fig shows the shearing of sheet metal between two cutting edges. After you insert the bend table in the drawing bend tags are added to the selected drawing view.
