What does the term gouge refer to?

The term gouge refers to a hole or groove made by a sharp tool, which is characterized by its physical properties resulting from the removal of material. In construction and manufacturing contexts, gouging often occurs when a tool, such as a chisel or router, is used improperly or when excessive force is applied, causing the tool to dig into the surface of a material. This is a critical concept in various operations, as it can affect the integrity of the material being worked on. Understanding gouging is important for ensuring precision in cutting and shaping materials, which is essential for safety and the quality of the final product.

The other options describe different phenomena; mechanical breakage refers to structural failures due to stress, corrosion involves chemical deterioration of materials, and an increase in material thickness typically pertains to processes such as welding or molding, which do not align with the definition of gouging.
