(from ASME Y14.5M-2009) Tolerances can be expressed: 1. directly to a dimension 2. geometric tolerance 3. in a note 4. The .40 is the distance from the edge and the 30 degrees is the angle starting at the .40 location. I uploaded an example. However, as I said, I'm nowhere close … Drawing Callout: Description: Concentricity, sometimes called coaxially, ... Concentricity in the ASME Y14.5 standard has a very specific set of applications outside of which this control should generally be avoided. As the designer, I would have made the 2X60° chamfer perpendicular to one of the edges. This would result in two chamfer-like flats along the length of the bracket on the inner edges of each leg. 45xd. It may result in a 60 degree or a 30 degree chamfer, depending which surface the machinist chooses to apply the dimension to. • If possible, match units to machine units. As far as the ASME Standard goes only a 45 degree chamfer can be dimensioned with a note. Such a feature is shown with a linear dimension and an angular dimension, or two linear dimensions. Explore global and U.S. market trends that are driving new thinking, designs, and technologies for the truck and bus, automotive, marine, and rail industries. It is not a good idea to dimension such a chamfer with a leader callout, as the angle is indeterminate. Whether you use the "__ x ___°" type or the "C__" type, either one is actually two dimensions. We surveyed nearly two hundred engineers, managers, educators and specialists who work with HMIs to understand how organizations are developing HMIs, the importance of HMIs to the product development process, and what tools are used to design and test HMIs. I knew it was there somewhere, I didn't have the spec here to look up. ASME Y14.5 is an established, widely used GD&T standard containing all the necessary information for a comprehensive GD&T system. I do not have a copy of the actual standard on my desk but I am looking at "Design Dimensioning and Tolerancing" by Bruce A. Wilson ASME Senior which is based on the ASME Y14.5M-1994 standard.

I actually specify stuff like this all the time, although, functionally, the feature never is a chamfer. Annotation standardization is provided by the ASME Y14 series of standards. RE: ASME … Attachments. is given first and is followed by a plus and minus expression of tolerance. It may result in a 60 degree or a 30 degree chamfer, depending which surface the machinist chooses to apply the dimension to.
