As paper moves forward along the forming wire on a papermaking machine, the fibers align themselves in a direction parallel to the direction of wire travel through the machine (also called machine direction).When paper is cut into sheets, it will be either long-grain (or grain-long) if

How grain size and direction affects sheet metal parts - 3ERP

2021-3-25 · This rolling process elongates the various crystals in the direction of the rolling, creating what we call a grain direction: the crystals are now longer along the length of the sheet, and shorter along the long transverse (width) and short transverse (thickness). These elongated crystals have important effects on the behavior of the metal.

2012-2-6 · direction perpendicular to the grain direction in the metal. By virtue of the rolled sheets being used for bending, the grain direction usually is along the length axis, being the direction of rolling. There is a possibility of cracks appearing at the time of bending if the bending is done along the grains. 31 Nageswara Rao Posinasetti February

Sheet metal grain direction? - The Home Shop Machinist

2012-1-18 · 01-18-2012, 11:36 PM. Your grain will run paralell to the length of the sheet. Bends are esier ( less pressure ) paralell to grain direction. However they are usually less consistant from one peice to the next. On hot roll as you get to 3/16" and thicker bending in line with the grain you can get cracking if you use a radius less than the

Bending Basics: Grain direction's effect on sheet metal

2022-3-24 · It takes more force to bend a piece of material when the bend line runs across the grain, but that same across-the-grain bend also can hold a much smaller inside bend radius. Also, the penetration depth can change from bend to bend, depending on the bend line's orientation to the material grain. Not all materials have a grain direction.

Crystalline Structure, Grain Direction and its Importance

Texture or grain direction must be taken into account for accurate predictions of material behavior and characteristics when forming/bending. A metal's strength is directly related to its grain size; reducing grain size is a common way to improve material strength which often has little to no effect on the material's toughness.

Metal Grains: The Hidden King of Metal Manufacturing

A grain is a collection of many repeating crystalline structures all oriented in the same direction. Grains can vary in length and width, depending on how long the repeating crystals go on for. When two grains oriented in different directions meet, a grain boundary is formed. As seen in the image below, this grain boundary phenomenon is due to

On the Relation of Grain Orientation and Opening Crack of

A notched 2024-T39 aluminum sheet with a thickness of 0.3 mm was torn, which polished by 180#, 320#, 600#, 800#, 1000#, 1200#, 1500# rough sand paper and 800#, 1000# fine sand paper before tearing. When the crack enters another misaligned grain, direction changing continues. That also leads to the crack behaving not a straight line. The

2018-8-7 · In general the structure of the normalised plate is finer. Plate bending can be split into two main categories, plate rolling and press braking. The latter consists of much tighter radii, therefore the risk of fracture is much greater and the need to bend perpendicular to the grain increases. Limitations on the minimum internal radius exist and
