Edges: Need to Know for Better Quoting 

Often machined parts have sharp edges. The edge definition clarifies whether that’s acceptable or whether a post-processing step is required.

Ignoring the edge information will affect your quoting accuracy. To get better results, please continue reading what we believe you need to know about Edges.

Burrs and other similar flaws can have a big impact on part's functionality and how much it costs to deburr it.

Markings in line with ISO 13715 can be used to describe the edge shape.

Chamfer Dimension

The chamfer dimension tells us the size and angle of the slanted edge that's been cut into the corner of a part. Specifically, it provides two key pieces of information: how wide the slanted edge is and what angle it's cut at.

45-Degree Chamfer ‘C’

The letter ‘C’ is used to show the chamfer of 45°. For example, C3, means a chamfer of 3mm width and 45° angle.
