Chamfer or Fillet: It’s More Than a Coin Toss

Chamfer or Fillet: It’s More Than a Coin Toss

Chamfer or Fillet: It’s More Than a Coin Toss

FYI, we just posted an article on ENGINEERING.com based on a thread on Eng-Tips Forums. I hope you enjoy it.

Chamfer or Fillet: It's More Than a Coin Toss


When and where to use chamfered or filleted edges is a question posed time and time again by design engineers and machinists.

RE: Chamfer or Fillet: It’s More Than a Coin Toss

Thanks Hailey.

I have some feedback I wanted to give: the intro section implies 'internal corners' per AJack's quote while the rest of the article applies mostly to external corners.

Might be good to try and clarify that point, perhaps tweak the sentence before the table:

"To try and shed some light on this question, <when looking at external edge breaks> the following are some basic factors to consider when making your machining decisions."

Or maybe change the 'title' above the table to

"Comparison Between Chamfer and Fillet <for External> Edges"

RE: Chamfer or Fillet: It’s More Than a Coin Toss

Thanks for the feedback KENAT, a clarification has been made.

RE: Chamfer or Fillet: It’s More Than a Coin Toss

Good point KENAT.

internal chamfers or fillets are not the same. The internal fillet will normally reduce stress and not be a source of cracking, where this is not guaranteed for a chamfer.
An article on this would interest me a lot, but would probably be very complex.
