Another notch which we will call a relief notch is set back (relieved) a certain dimension from the edge. This is to keep the material from fracturing while forming the metal. Normally that dimension is called out on the blueprint. Sometimes this notch is used for parts with a large bend radius. The previous notches can be used with a large bend radius if a relief hole or slot is used in the corner (see Bend Reliefs). If no relief distance is called out on the print and you are using a large bend radius with this type of notch then to be safe use a minimum distance of the material + the bend radius.It is possible to see a variation or combination of some or all of these notches on the same part.Below is an illustration of a corner to corner with relief notch combination for a large bend radius. If depth or specified distance is not called out on the print then minimum distance would be material thickness plus bend radius. The two distances are normally the same dimension but can be different.
