ABSTRACT:
A fixture includes an enlarged plate having slots in an upper surface, and support members are secured to the plate at the slots. The fixture is utilized to machine parts that are initially flame-cut from a large plate/sheet of hot-roll steel. A plurality of notches are flame-cut into the perimeter of the part. The support members engage the flame-cut slots to secure the part to the plate for machining a first side of the part. Precision notches are machined into the part, and precisely-shaped protrusions on the support members are closely received in the precision notches to precisely locate the part for further machining on a second side thereof.
