90' bending tool. In the case of bending tools they are classified by the kind of generated bends. They can be constructed to adjust the bending angle by reference, stroke measurement or angle measurement. CNC machines usually abstain from a reference part. They grant a high bending accuracy starting with the first work piece.
A joggle bend in sheet metal (at top of image) and a hand joggling tool Joggling , [ 5 ] also known as joggle bending , is an offset bending process in which two opposite bends with equal angles are formed in a single action creating a small s-shape bend profile and an offset between the unbent face and the result flange that is typically less ...
Press tools are commonly used in hydraulic, pneumatic, and mechanical presses to produce the sheet metal components in large volumes. Generally press tools are categorized by the types of operation performed using the tool, such as blanking, piercing , bending , forming , forging , trimming etc.
The K-factor is the bending capacity of sheet metal, and by extension the forumulae used to calculate this. [1] [2] [3] Mathematically it is an engineering aspect of geometry. [4] Such is its intricacy in precision sheet metal bending [5] (with press brakes in particular) that its proper application in engineering has been termed an art. [4] [5]
In the metal trades area, marking out consists of transferring the engineer's plan to the workpiece in preparation for the next step, machining or manufacture. Calipers are hand tools designed to precisely measure the distance between two points. Most calipers have two sets of flat, parallel edges used for inner or outer diameter measurements.
