In stainless steel, it can be tough and sometimes impossible to define the grain and grain direction. Materials with a grain direction that affect the bend angle are considered anisotropic . Materials that don’t have this property are considered isotropic .7. Grain Direction. During the process of turning ingots of metal into sheet at the . LT-Long Transverse: perpendicular to direction of principal metal extension. In products whose grain structure clearly shows directionality (width-to-thickness ratio greater than two) it is that perpendicular direction parallel to the . The direction of the grain is an important factor to consider before any sheet metal fabrication process, but especially before bending, folding, and similar deformation processes. This is because grain direction makes sheet .
7. Grain Direction. During the process of turning ingots of metal into sheet at the mill, the metal is forced between a set of rollers. This process elongates the metal crystals, . When working with plate, pay close attention to whether you are forming with (longitudinal) or across (transverse) the grain direction (see Figure 1). A plate’s grain direction comes from the mill’s rolling process, which .
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 . Improve your sheet metal bending techniques with these 8 design guidelines. Learn how to create precise bends and avoid costly mistakes.
Learn about grain orientation and its impact on forming sheet metal. Find out the implications of bending with or against the grain for crack manifestation. Well, SOLIDWORKS strikes again by making it easy to implement the Grain Direction function on a Sheet Metal Flat Pattern to the desired results. For starters, inserting a . Question: A previous article of yours suggests that forming “with” the grain direction will manifest cracks. I might be confused over the verbiage. Does this mean the grain runs perpendicular or parallel to the bend line? I was .
Have you encountered challenges with Grain Direction in sheet metal? Do you just want to know what that’s all about and how you can make the entire process .The fundamental relationships between grain orientation, deformation-induced . tions of one specimen in the rolling direction of the sheet and one in the transverse direction. Maps of . mechanical behavior of metal sheet under a wide range of defor-mation conditions. This need is particularly acute for new high This has to do with the sheet grain direction. Where Does Grain Direction Come From? The grain direction is in the rolling direction of the sheet as it was being manufactured. Two rollers compressing the hot metal cause the polycrystalline material to elongate in the direction of rolling. . Bending the sheet metal longitudinally (with the .
So L-T means loaded in L direction with crack propagating in T direction. On the other hand, the MMPDS-07 describes Test Directions as: L-Longitudinal: parallel to the direction of principal metal extension during manufacture of the product. LT-Long Transverse: perpendicular to direction of principal metal extension. The same tooling and machinery are simply reprogrammed to make a variation rather than something entirely different. Setup of that production line and the methods used to bend sheet metal are important to sheet metal design. CAD details have an impact on fab shop setup. As an example of bad design for manufacturing, consider Figure 1a. The .
The bounding box algorithm finds the smallest area in which to enclose the flat pattern for the part. At times, the direction of the bounding box is not very effective (Figure 1). When this occurs, you can specify the bounding box in any direction by using a sketch or an edge in the Grain Direction option in the FeatureManager (Figure 2).
You can set a grain direction to determine the smallest rectangle that aligns with the grain direction to fit the flat pattern (see Flat-Pattern PropertyManager). The bounding box is represented by a sketch when you flatten the sheet metal part and is located in the FeatureManager design tree under Flat-Pattern. You can also create a bounding .In SOLIDWORKS Sheet Metal, the bounding box algorithm finds the smallest area in which to enclose the flat pattern for the part. At times, the direction of the bounding box is not very effective. When this occurs, you can specify the bounding box in any direction by using a sketch or an edge in the Grain Direction option in the FeatureManager. 1. We put a note for graining in a few of our sheet metal fab drawings note blocks. It says "9. GRAIN IN DIRECTION SHOWN". I also have a Grain-horz.sldblk file with a line with arrow heads on both ends and a box above the line with a 9 in it. But that means I have to explode the block if I want to change the note number, which I sometimes need to .

Applying this to metal bending, be it plate bending, press braking or any other type of metal forming, consideration must be given to the grain direction before any process is carried out. As a general rule, the grain line must run perpendicular to the bend to avoid the potential for cracking or fracture. In cases where there are multiple bends .
On sheet metal parts, we often have to consider both grain direction and "good side." As a rule, I orient grain in the X direction of the flat pattern and the good side is face as "front." However, it is easy to make a mistake especially as the parts become more complex as it is more natural to mark these two attributes at the folded part level. I am in search of a way to apply grain constraints (whether or not a part is rotatable for nesting on a sheet) to sheet metal parts in the model for manufacturing purposes. We currently place "dumb" labels in the .idw to describe the rotate ability of parts, particularly on polished stainless steel. Our Cam software(s) use the x-axis when a grain constraint is applied to the part. In stainless steel, it can be tough and sometimes impossible to define the grain and grain direction. Materials with a grain direction that affect the bend angle are considered anisotropic. Materials that don’t have this property .
