These variations created problems for shops trying to provide deburring solutions and for customers trying to figure out what solutions to look for.
Burr direction in sheet metal.
Figure 3 a microcrack that occurred during.
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.
De burring can be avoided by considering the direction of the burrs in the design of the parts.
These methods are used to more accurately detect minute amounts of metal.
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.
Adjust so that the cutting is uniform.
An unclear definition of burrs was a problem manufacturing faced for many years.
Apart from the above there are other causes of burr generation.
They include burrs fracture burnishing rollover and work hardening.
If operators and technicians try to solve cut quality problems without considering the process fundamentals they may be shooting in the dark.
Creation of a formed feature by angular displacement of a sheet metal workpiece.
Metal burr extending beyond the edge of the cut piece view on the cut face top and from the bottom bottom a burr is a raised edge or small piece of material that remains attached to a workpiece after a modification process.
Burr height up to 10 of material thickness can be expected.
Burrs can interfere with subsequent forming processes.
Burr direction side of the stock on which burrs appear.
In manufacturing practice sharp tools can mitigate burrs.

What is a burr and how is a burr defined.
It is usually an unwanted piece of material and is removed with a deburring tool in a process called deburring.
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.
The parts that have been cut neatly are the parts where the clearance is small.
2 workpiece resulting from blanking operation.
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.
The burr is a thin ridge of material that is formed due to the elongation of metal during the final separation of the sheet.
More ductile metals tend to form larger burrs.
Stamping includes a variety of sheet metal forming manufacturing processes using a machine.
Burr is a metal part of the metal casting milling or electroplating process metal surface residual or extremely fine microscopic metal particles.
