Metal of extremely high tensile strength may move regardless but in most situations as long as the clamping pressure is adequate to overcome the resistance your bend will be accurate wold said.
Punched bent sheet metal frc.
The metal in the areas where holes and slots are punched gets stretched and become more tensile which gives more structural rigidity to the sheet metal.
Another way of strengthening the sheet metal is by punching holes and slots.

The punch tip radius usually has little influence.
In principle does not seem that this operation is complicated and difficult.
Does this mean that one size punch tip radius will work well with every application.
Troy products focuses on products geared toward public safety vehicles and similar apparatus.
With a 25 000 square foot shop located in montebello ca troy sheet metal works services the industrial market nationwide.
Sheet metal should be bent at the minimum bend radius possible.
Minimum punch radius 63 of the material thickness.
The metal forms to a natural radius based on the size of the die v opening.
As the name bottom pressing suggests the punch presses the metal sheet onto the surface of the die so the die s angle determines the final angle of the workpiece.
The bend radius you select may not be available if the geometry of the part will not allow us to bend with the specific tooling required to achieve that radius.
Bottoming is also known as bottom pressing or bottom striking.
Instead the sheet metal punch can be saved for making holes where the excess material needs to be bent into a specific shape.
The bending of sheet metal with a punch and an array mounted at a folder is quite natural and normal.
As with any mechanical parts cutting and shaping process sheet metal punching can create sharp edges and burrs from time to time.

With bottoming the inner radius of the angled sheet depends on the die s radius.
