Metal Rolling Processes and Equipment

A collection of flashcards covering essential vocabulary and definitions related to metal rolling processes and equipment as outlined in the lecture notes.

Metal Rolling

A manufacturing process that involves reducing the thickness or changing the cross-section of a metal piece by passing it through rollers.

Hot Rolling

A process where metal is rolled at a temperature that is above its recrystallization temperature, improving ductility.

Cold Rolling

A finishing process that occurs below the recrystallization temperature, increasing strength through strain hardening.

Sheet Metal Processes

Techniques used to shape metal sheets into usable forms, including blanking, punching, and bending.

Elastic Recovery

The tendency of a metal to return to its original shape after being deformed within its elastic range.

Ductility

The ability of a material to deform under tensile stress without breaking.

Anisotropy

The property of a material to exhibit different physical properties in different directions.

Thread Rolling

A method for creating threads on a fastener by deforming the material through rolling.

I-Beam Rolling

A specific type of shape rolling process used to produce I-beams used in construction.

Forming Processes

Processes that involve shaping materials through various methods such as pressing, molding, and stamping.

Flat Rolling

A metalworking process in which a metal workpiece is passed through rolls to reduce its thickness and create flat sheets or plates.

Internal Stress

The stress that develops within a material due to external forces, temperature changes, or phase transformations, which can affect its structural integrity and performance.

Blanking

A manufacturing process where flat sheets of metal are cut into shape, removing waste material to create parts directly.

Punching

A manufacturing process that involves using a tool (punch) to cut holes or shapes in a sheet of metal, often creating scrap material in the process.

Bending

A metal forming process that involves deforming a workpiece around a predetermined axis, creating a bend without altering the material's overall thickness.

Stamping 

A manufacturing process that involves pressing a flat sheet of metal into a desired shape using a die, often used for high-volume production of small to medium-sized parts.
