Which process consists of materials passing through a series of rollers that reduce their thickness?

1. Machining

2. Bending

3. Rolling

4. Stamping

The correct answer is: Rolling

The process where materials pass through a series of rollers to reduce their thickness is known as rolling. In rolling, the material, often in the form of sheets or plates, is fed through a pair of rolls that apply pressure, causing the material to deform and become thinner. This process can also improve the material’s mechanical properties due to the work hardening that occurs as it is shaped. Rolling is widely used in industries for metalworking, as it can produce long sheets or strips of material with uniform thickness, which is essential for downstream manufacturing processes. The other processes, while related to material shaping, serve different purposes: machining involves removing material to achieve desired dimensions or finishes and is usually not focused solely on thickness reduction. Bending refers specifically to the alteration of material shape without necessarily reducing thickness, often creating angles or curves in the material. Stamping is used for cutting or forming materials with a die, rather than incrementally thinning them, so it does not involve the rolling action associated with thickness reduction.
