Burr height up to 10 of material thickness can be expected.
Burr direction in sheet metal.

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.
The sheet metal stamping process is a very fast and precise manufacturing process.
Clearly the formation of burr should be avoided whenever possible.
To the edges where burrs may occur to reduce the occurrence of burrs.
In those instances deburring is necessary.
Add grooves cuts rounded corners etc.
Which manufacturing methods leave a burr.
De burring can be avoided by considering the direction of the burrs in the design of the parts.
So it is very important to design an economy friendly and time saving press tools.
More ductile metals tend to form larger burrs.
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.
Stamping includes a variety of sheet metal forming manufacturing processes using a machine.
These combined costs are compared to sheet metal prices for an anticipated cost savings.
The burr is a thin ridge of material that is formed due to the elongation of metal during the final separation of the sheet.
It is usually an unwanted piece of material and is removed with a deburring tool in a process called deburring.
For elevator stainless steel sheet metal parts the product design department considers the burr formation mechanism and removal method at the product and process design stage to minimize burrs.
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.
But as a side product of many manufacturing methods it is often unavoidable.
They include burrs fracture burnishing rollover and work hardening.
Burr commonly occurs when producing sheet metal parts using different manufacturing methods.
But what if press tool is not working efficiently or it takes many more operations to produce stamped parts.
Burr direction side of the stock on which burrs appear.
Metal stamping is utilized for cost effiency when a sheet metal requirement has a significant quantity range.
2 workpiece resulting from blanking operation.
Figure 1 the sheared edge exhibits some distinctive characteristics.
Figure 3 a microcrack that occurred during.
The metal stamping quote will include the cost for the tooling tool die set to produce the parts and also the part cost.
If operators and technicians try to solve cut quality problems without considering the process fundamentals they may be shooting in the dark.
Steps to design any sheet metal stamping press tool or die.
Burrs can interfere with subsequent forming processes.
