Item 168753 model 11786.
Sheet metal joggle dimensions.
I am needing the joggled area to be vertical as it s shown on the pdf.
Previous editions covered economic order quantity in batch production and the accuracy of things made from rolled sheet stock.
Insert the sheet in the brake and bend the metal up approximately 20 to 30.
A joggle is an offset formed to provide for an overlap of a sheet or angle which is projecting in the same plane.
Next month concludes with the pros and cons of hems jogs and forming tools.
Uncontrolled dimensions contain two different categories of tolerances.
Remove the part from the brake and check the joggle for correct dimensions and clearance.
I appreciate any suggestions etc.
I tried using the flange but it follows the bend line.
The inside joggle radii should be approximately the same as used for straight bending.
Release the brake and remove the part.
This then becomes an operation for one of our cnc press brakes.
Bend the part up until the correct height of the joggle is attained.
Columnist gerald davis continues a discussion of 3 d cad and precision sheet metal manufacturing in part iii of a four part series focusing on design guidelines for sheet metal.
Once dimension x increases in the joggled formed in the sheet metal above the maximum shown in the table we have to put the 2 bends into the sheet separately.
1 all manufacturing tolerances used up to that point such as laser cutting tolerances welding tolerances and more 2 all bend tolerances for the entire part added together we call this an uncontrolled dimensions because there are additional tolerances to consider.
Hillman 12 in x 24 in cold rolled steel expanded sheet metal.
A joggle bend in sheet metal and a joggling tool joggling 5 also known as joggle bending is an offset bending process in which the two opposite bends are each less than 90 see following section for how bend angle is measured and are separated by a neutral web so that the offset in the usual case where the opposite bends are equal in.
