Manufacturing engineering

The unwanted ragged edge left after cutting metal

In manufacturing a burr is the unwanted projection of material pushed out at the edge of a workpiece by a cutting, drilling, punching or grinding operation, left behind when the tool exits and the metal deforms rather than cleanly separating. Aurich and colleagues' 2009 CIRP review Burrs—Analysis, control and removal treats how burrs form, how they are classified and measured, and how they are prevented or removed by deburring, since they spoil fit, interfere with assembly and can injure handlers. The referent is a defect at a machined edge, specified by its size and type, entirely distinct from a drypoint's prized ridge, a plant's seedcase, or a cranial opening.[1]

Unit
The height, thickness and type of the edge projection left by a machining operation
Recovery means
Not applicable
Measured by
Quantified by optical and profilometric measurement of burr height and thickness at the cut edge
