==Description==
A bending brake is a metalworking machine that allows the bending of sheet metal. The brake is a Chicago W31 steel box and pan brake. The max material thickness capacity of this machine is 16 gauge mild steel. In a box-and-pan brake (also known as a finger brake), the clamping bar includes several removable blocks, which may be removed and rearranged to permit bending of restricted areas of a piece of sheet metal or of already partially formed pieces. After bending, a box or pan form is then completed by screw, solder, weld, rivet, or other metal fixing process.
Here is an example of this piece of equipment being used.

==Training==
====Operation====
Insert Text
====Demonstration====
To demonstrate competency on the Bending brake you will be required to bend a piece of sheet metal to a 90 degree angle.
====General Procedure====
=== Bending Steps ===
=== Bending Steps ===
#Ensure that your sheet metal is thinner or equivalent to 14-gauge sheet metal, and ensure that it is less than 48" in width.
#Ensure that your sheet metal is thinner or equivalent to 16-gauge sheet metal, and ensure that it is less than 48" in width.
#If making a bend for a box or a pan, adjust the fingers so that the equivalent width of the fingers is just shorter than your sheet metal.
#If making a bend for a box or a pan, adjust the fingers so that the equivalent width of the fingers is just shorter than your sheet metal.
#Adjust the clamping force and the clamping handle to allow room to insert your work piece.
#Adjust the clamping force and the clamping handle to allow room to insert your work piece.
#Insert your work piece to the line you want to bend, centered in the brake, and clamp your piece securely.
#Insert your work piece to the line you want to bend, centered in the brake, and clamp your piece securely.
#Pull up on the bending handle of the leaf slowly until your piece is bent to the desired angle, and slowly lower the leaf.
#Pull up on the bending handle of the leaf slowly until your piece is bent to the desired angle, and slowly lower the leaf.
#If the piece does not bend straight, unclamp the handle on the overbent side and adjust the top leaf.
#If the piece does not bend straight, unclamp the handle on the over-bent side and adjust the top leaf.
#Adjust the clamp handle, and remove your piece.
#Adjust the clamp handle, and remove your piece.
#Put back any fingers if adjusted, and deburr if any rough edges are left.
#Put back any fingers if adjusted, and deburr if any rough edges are left.

=== Safety ===
#Always make sure your hands are out of the way of the fingers and all moving parts.

#If bending a small piece of metal, place it in the center of the brake.
#If bending a small piece of metal, place it in the center of the brake.
#You may not use the sheet metal machines without safety glasses!! (Should be obvious if you are following the rules of the shop)
#Do not attempt to bend material thicker than 16 gauge.
== Parts of the Machine ==
#Only use sheet metal with the brake. Don't try to bend round material!
