For sheet metal work over 140mm long please see our cnc z bend table.
Sheet metal joggle dimensions.
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.
Insert the sheet in the brake and bend the metal up approximately 20 to 30.
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.
The inside joggle radii should be approximately the same as used for straight bending.
This then becomes an operation for one of our cnc press brakes.
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.
A joggle is an offset formed to provide for an overlap of a sheet or angle which is projecting in the same plane.
Turn the part over and clamp it in the brake at the second bend line.
I appreciate any suggestions etc.
Remove the part from the brake and check the joggle for correct dimensions and clearance.
Item 168753 model 11786.
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.
I have attached a pdf of a part i m working on in inventor.
Uncontrolled dimensions contain two different categories of tolerances.
Next month concludes with the pros and cons of hems jogs and forming tools.
Bend the part up until the correct height of the joggle is attained.
