Chamfer Callout?
Chamfer Callout?
(OP)
what is the standard for a callout of a chamfer feature? is it to call out the note with a leader (.25 x 45°) or to add two seperate dimensions (one linear and one angle)?
Thanks in advance

RE: Chamfer Callout?
Per ASME Y14.5M-1994, Chamfers may be dimensioned by a linear dimension and an angle, or by two linear dimensions. If it is a 45 degree chamfer, a note may be used.

Also, I believe the new way to dim an angle is without the word "cham" or "chamfer", just the dim ".02x60°".

RE: Chamfer Callout?
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". As a memory jogger for the proper order, I think of the word "dangle". Chamfer notes 'dangle' on a leader off the end of the shaft and are specifed as Distance X ANGLE.
Many of my machinist friends and I still can't figure out why it was changed since "it wasn't broken" before.
