Deburring and Edge Chamfering: Burr Removal Does Not Define a Controlled Land

Name the requested edge result

Harvey describes chamfer mills as tools that can both create chamfers and deburr parts. Tool identity alone therefore does not define the required edge result. Primary reference: Harvey technical explanation.

Compare fictional edge records

Imagine drawing A requests removal of a protruding burr and supplies no chamfer dimension. Drawing B specifies a 45° edge feature with 0.5 mm axial and radial legs. The latter ideal section has a sloped land length of 0.5√2, about 0.707 mm.

A burr-free observation for A does not automatically demonstrate B. Conversely, a dimensioned bevel can still leave an unwanted remnant elsewhere. These drawings are invented to separate outcomes; they are not general edge-break allowances or recommended dimensions for an actual machine component.

Use separate evidence fields

Record the permitted parent-edge change, the specified chamfer geometry if any, and the method used to examine residual burrs. Keep the land dimension separate from a statement that the surface feels smooth. Identify the relevant adjacent features before assuming material removal is unrestricted.

The same tool can participate in both tasks, but their acceptance evidence need not be the same. This worksheet helps a fabrication reviewer obtain an unambiguous edge requirement and verify the corresponding result. It does not prescribe manual handling, a cutting path or a universal chamfer size for every exposed edge.
