Engineering Sheet Metal Drawing Notes

After you insert the bend table in the drawing bend tags are added to the selected drawing view.

Engineering sheet metal drawing notes.

Engineering drawing basic sheet layout title block notes engineering working drawings basics. 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 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. Punch begins to push into work causing plastic deformation 3.

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 an effective way of communicating technical ideas and it is an essential tool in engineering design where most of the design process is graphically based. Drawing force power and number of stages defects in products. Bend tags associate rows in a bend table with the view geometry.

How to dimension a drawing. 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. The proper relation of views in a drawing.

The shearing action is illustrated in the figure. 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. Bend notes are associated with a drawing view.

Engineering graphics is used in the design process for visualization communication and documentation. Cutting of sheet metal is accomplished by a shearing action between two sharp edges. Just before the punch contact work 2.
