chamfer 3

[xgrigorix]

I have a cylindrical part with a chamfer at each end.
Is the correct callout for this "2X 0.031 X 45°" or does each chamfer need to be noted individually?

Thanks.

As usual ctopher, ewh and MechCT have my complete agreement.

The goal of any drawing is clear, concise communication. Views, dims, tols, notes, etc should be chosen with that in mind. After doing your best to accomplish that including the application of industry and company standards, there is a simple test to see how well you've done. If the fabricator doesn't understand the drawing and calls with a question, the drawing is incorrect or incomplete.

Another way I've seen drawings checked is for another designer or engineer to recreate the model based only on the drawing. If it agrees with the original model then there is that much more confidence in the drawing. Unfortunately with today's tight schedules, this isn't done too often.

In SolidWorks, I have had models turn all red based on drawings from other companies. IMO, If SW doesn't like it, it can't get machined.

Chris,

I will agree with that statement (sheet metal being an exception)... with the stipulation that even if solidworks DOES like it, sometimes it CAN'T be machined either.

True. I am looking at it at a CAD/CAM view.
The model can work, but depends on how the drawing is dimensioned if some features can be machined or inspected.

sorry, I'm not thinking straight today...too much going on...1 more hour
