Login with my Xometry account Indicate chamfers on technical drawing in sheet metal
Hello everyone, I am working on the design of sheet metal parts. Can anyone tell me how to indicate chamfers on my drawing?
Hello,
For sheet metal parts, it is good to indicate countersinks/milling in 3 dimensions on the plans and to indicate the largest diameter as well as the angle. For an angle corresponding to a 45° chamfer (the most classic), one traditionally indicates a milling at 90°, which corresponds to the angle of the cone of the milling cutter or punch used.
It is sometimes enough to show only a top view, and to indicate the presence of countersinks by a double circle, specifying ⌵ symbol the external diameter, the angle and the number of occurrences.
For example: "⌵ Ø 19 x 90°" (example here: https://www.gdandtbasics.com/countersink).
