      I am working with a slew of drawings for milled 6061 aluminum. Most of them do not have the "Break Sharp Edges" note. Are there any value to not breaking edges. Thanks.

      It is essential to break sharp edges on any part - whatever the material is - to avoid injuries to people who may be using this part:-
      a) To people who may be assembling these parts together to make a product.
      b) To people who may be using the end product.
      Additionally, if you are going to anodise the aluminium part - then it is essential to (ideally radius) the edges - since anodising is easily broken on sharp edges.

      In special circumstances you want sharp edges, but in most cases they should be broken. A good machinist will generally do so even if it's not called out on the drawing, but it's usually (especially if a part is being made outside) to call it out, often in a standard note.

      If for some reason you do need it sharp, it should be explicitly noted.
