What is a chamfer?

What is a chamfer?

A chamfer is an angle on the edge of a workpiece most often formed through cutting material away. The edge can be the outside of the part, where a hole breaks through a surface or many other combinations of surfaces meeting.

How do you call out a 45 degree chamfer?

What is the correct way to call out a 45 degree chamfer? Y14.5 clearly says a note 1 X 1 or 1 X 45° is allowed. Solidwork has a dimension style that is C1 for 45 degree chamfers. I have been using this style for many years with multiple companies and drafting programs and have never questioned it.

What is the proper way to call out a chamfer?

Chamfers are now properly called out with the distance first and the angle second, .25 X 45 deg per ASME Y14.5M-1994. Previously, ANSI Y14.5M-1982 had them the other way around, "angle X distance".

What is the angle of a chamfer?

Chamfer angles are often assumed to be the same angle as the tool used to generate them. The most common chamfer angle is 45 degrees. Depending on the part geometry, different tools can be used to measure a chamfer’s angle. The angle can be calculated using the triangle calculator referenced above or a protractor can be used.
