Burr Direction In Sheet Metal

Burr direction in sheet metal.

Every manufacturer and industry segment defined a burr differently. Stamping includes a variety of sheet metal forming manufacturing processes using a machine. Figure 3 a microcrack that occurred during. Burrs can interfere with subsequent forming processes.

If operators and technicians try to solve cut quality problems without considering the process fundamentals they may be shooting in the dark.

De burring can be avoided by considering the direction of the burrs in the design of the parts. Inspectors can use a range of tools like toothpicks locates burrs and steps as small as 0 0005 inches pencils assesses whether or not a burr is rigidly adhered and a fingernail detects burr height and sharpness. The burr is a thin ridge of material that is formed due to the elongation of metal during the final separation of the sheet. Burr is a metal part of the metal casting milling or electroplating process metal surface residual or extremely fine microscopic metal particles.

Attaining a burr free cut is about ensuring the beam parameters and gas dynamics work together to ensure the right amount of molten metal evacuates the kerf at the right time and in the right way. In manufacturing practice sharp tools can mitigate burrs. Apart from the above there are other causes of burr generation. Figure 1 the sheared edge exhibits some distinctive characteristics.

Figure 2 a burr or protruding ragged edge shown at 100x magnification occurs as the material is sheared at an angle against the blanking direction. These methods are used to more accurately detect minute amounts of metal. The parts that have been cut neatly are the parts where the clearance is small. These variations created problems for shops trying to provide deburring solutions and for customers trying to figure out what solutions to look for.

What is a burr and how is a burr defined. An unclear definition of burrs was a problem manufacturing faced for many years. The clearance is large where the fibers of the paper are remaining uncut or where the vinyl sheet has been cut so that it is stretched. They include burrs fracture burnishing rollover and work hardening.

Burr height up to 10 of material thickness can be expected. It is usually an unwanted piece of material and is removed with a deburring tool in a process called deburring. More ductile metals tend to form larger burrs.
