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. [1] It is usually an unwanted piece of material and is removed with a deburring tool in a process called deburring.
These are often used in CNC machining centers for removing burrs (the small flakes of metal) after a machining process. To achieve optimal surface speed and cutting conditions, burrs are rapidly rotated at high speeds, often in the range of thousands or tens of thousands of RPM , which is typically the maximum speed supported by a given spindle.
After compression, the part shears for about 10% of the part thickness, and then fractures free of the strip or sheet. This fracturing produces a raised, jagged edge which is called a "burr". Burrs are typically removed by tumbling in a secondary process. Burr height can be used as an important indicator of tool wear.
Belt grinding is a versatile process suitable for all kinds of different applications. There are three different applications of the belt grinding technology: [3] Deburring: Radiusing, burr removal, edge breaking; Finishing: Surface roughness, removal of micro burrs, cosmetic finishes, polishing
Shearing, also known as die cutting, [1] is a process that cuts stock without the formation of chips or the use of burning or melting. Strictly speaking, if the cutting blades are straight the process is called shearing; if the cutting blades are curved then they are shearing-type operations. [2]

The U.S. Preventive Services Task Force released a draft recommendation advising against using vitamin D to prevent falls and fractures in people over 60. Pharmacist Katy Dubinsky weighs in.
Burnishing may also affect the performance of a machine. The plastic deformation associated with burnishing creates greater heat and friction than from rubbing alone. This reduces the efficiency of the machine and limits its speed. Furthermore, plastic deformation alters the form and geometry of the part.
