Cutoff Burrs and Chamfers
Cutoff burrs in many instances will not interfere with the function or appearance of a precision machined product. Whenever it is possible to allow a cutoff burr to remain on a piece, a note should be used as shown in Drawing #9. If a cutoff burr will interfere with the function of a component, a note “Remove Cutoff Burr” should be placed on the drawing.
The acceptable limit for the cutoff burr must be dimensioned to aid the producer and the inspector.
Cutoff burrs can be removed by one of several methods. Some methods may leave a depression in the end of the piece. The finished condition of the surface from which the burr is removed should be referenced in a note if it is a critical surface.
