Chamfer - Wikipedia, the free encyclopedia
Says here that a chamfer is a beveled edge connecting two surfaces.
According to Merriam Webster, a bevel is a slanted edge and a chamfer is a beveled edge.
How can I interpret this? Isn't that the same?
*Not a Teacher*
Chamfer and bevel are usually interchangeable. But if you want to get technical, there is a bit of a difference. The pictures on the Wikipedia page demonstrate the differences between the two pretty well.
I see it now. A bevel is a sloped edge and that probably refers to any slanted edge in general. A chamfer, more technically, is a beveled edge connecting two surfaces (and that would be three sides, like in the picture).
In non-specialist usage, you hear bevel; until I read this thread, I was unaware of the distinction and had never heard the word chamfer . I must go and look for one to use the word.
The difference is in degree. To illustrate, imagine the cross section of a non-bevelled, non-chamfered part. It will have 4 surfaces, two in each plane- vertical and horizontal- and each pair parallel. There will be four 90-degree corners.
A bevelled edge will still have 4 surfaces, but two of them are no longer parallel and one corner comes to a sharp point- often at 45 degrees, but not by definition.
A chamfered edge will have 5 sides, because the angled surface does not meet the lower horizontal. There are still two pairs of parallel sides with the addition of one angled surface, typically at 45 degrees but again, not by definition.
A good example is a kitchen countertop. Kitchen countertops are often referred to as "bevelled" when they actually are chamfered. This is to avoid confusion- the general public don't know what a chamfer is.
