Answer:
Shearing - Shearing, also known as die cutting, is a process which cuts stock without the formation of chips or the use of burning or melting. Strictly speaking, if the cutting blades are straight the process is called shearing; if the cutting blades are curved then they are shearing-type operations.
Scouring - Scouring is the pretreatment process of wet processing technology. ... Scouring process bears an impotency in wet processing. Scouring is the process by which natural (oil, wax, gum, fat etc) as well as added (during fabrication process) impurities are removed completely as possible.
Scoring - Scoring is a process in which one cuts a groove into rigid material (usually tile, stone, glass, etc.). This groove is used to either break the material along the slit, for decoration, or act as a guideline for other processes such as painting.
Dyeing - A dyeing process is the interaction between a dye and a fibre, as well as the movement of dye into the internal part of the fibre. Generally, a dyeing process involves adsorption (transfer of dyes from the aqueous solution onto the fibre surface) and diffusion (dyes diffused into the fibre).
Rollang - In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. ... Most steel mills have rolling mill divisions that convert the semi-finished casting products into finished products.
