“What is a fillet, and what is a chamfer?” You probably wondering what’s the answer for this question, especially you are working on mechanical engineering drawing for some custom mechanical parts.
It is very important to know the difference between a fillet and a chamfer. A fillet is the rounded edge of an object. A chamfer is the end of an object that has been cut off at an angle.
1) Fillet: The rounded edge of an object
2) Chamfer: The end of an object that has been cut off at an angle
What is a Fillet?
In mechanical engineering, a fillet is a rounding of an interior or exterior corner of a part design. An interior or exterior corner, with an angle or type of bevel, is called a “chamfer”. Fillet geometry, when on an interior corner is a line of concave function, whereas a fillet on an exterior corner is a line of convex function (in these cases, fillets are typically referred to as rounds). Fillets commonly appear on welded, soldered, or brazed joints.
There are three types of fillet mechanics: miter, concave, and convex fillets. On the interior side, fillets are concave, while on the exterior, they are convex. Engineers use fillets to reduce the stress on a part. The fillet is a common engineering feature that is used to create rounded corners. The purpose of the fillet is to reduce stress concentration at the corner of a part.
