Define and describe the proper use of bend instructions according to ASME Y14.31-2008, Undimensioned Drawings, and include a definition and description of principal plane in your discussion, also give at least two examples of bend instructions.
What will be an ideal response?
Bend instructions are placed in a note next to the bend line. Bend instructions generally specify the number of degrees of the bend and the bend direction from the principal plane. The principal plane is the surface from which the bend is formed. Bend instructions are placed on the principal plane when possible. Place the bend instructions outside and adjacent to the principal plane when there is not enough space on the principal plane. The bend instruction can have a variety of formats, but they commonly specify the bend direction, bend angle, and bend radius. The following are examples of bend instructions: UP 90° R.120, DOWN 90° R.120, DN 90° R.120, BUP 90° X R. 250, BDN 90° X R. 250.
