FEEDS. Various devices that move stock or workpieces to, in, or from a die.

FERRITE. A solid solution in which alpha iron is the solvent, and which is characterized by a body-centered cubic crystal structure.

FINISHING TEMPERATURE. The temperature at which hot mechanical working of metals is completed.

FLANGE. A projecting rim or edge of a part, usually narrow and of approximately constant width for stiffening or fastening.

FLATTENING. Removing irregularities of a metal surface by a variety of methods, such as stretching, rolling, and/or roller leveling of sheet and strip.

FLYWHEEL. A heavy, rotating wheel, attached to a shaft, whose principal purpose is to store kinetic energy during the nonworking portion of the press cycle and to release energy during the working portion of the press cycle.

FOOT CONTROL. The foot-operated control mechanism (other than mechanical foot pedal) designed to control the movement of the ram on mechanical, hydraulic, or special-purpose power press brakes.

FORMING. In the context of "Sheet Metal Formability," the term forming covers all operations required to form a flat sheet into a part. These operations include deep drawing, stretching, bending, buckling, etc.

FORMING LIMIT DIAGRAM (FLD). A diagram describing the limits that sheet metal can be stretched under different conditions.

FRAME. The main structure of a press.

FRONT-GAGE. Same as back-gage except that the locating fingers or surfaces are in front of the shear bed blade.
