Blanking is a term that is used in various fields and can have slightly different meanings depending on the context. In manufacturing and engineering, blanking refers to a process in which a flat piece of sheet metal or paper is punched or cut to create a desired shape or outline. This process is typically carried out by using a machine or a press tool known as a blanking die. The purpose of blanking is to produce individual parts or components that can later be used in the assembly of a larger product.
In the field of computer science and electronics, blanking refers to the act of erasing or clearing a specific portion of the screen or display. This is commonly seen in cathode-ray tube (CRT) monitors or televisions, where the vertical and horizontal retrace lines temporarily turn off the electron beam to avoid damaging the display and prevent the formation of a visible line during the return to the starting position. The blanking process ensures a clean and continuous image display without any distortion or flickering.
Moreover, in psychology or cognitive science, blanking is a phenomenon where an individual experiences a temporary or sudden loss of memory, focus, or attention. This can occur due to various factors such as stress, fatigue, or mental overload. Blankouts can cause a person to forget what they were doing, lose track of time, or simply experience a lapse in awareness.
Overall, blanking can refer to cutting or shaping materials, erasing or clearing screens, or experiencing memory lapses, depending on the specific field or context in which it is used.
The term "blanking" originates from the Old English word "blanc", which means "white" or "shining". Over time, it evolved to possess various meanings, such as "to make or become white", "to make or become pale", or "to erase or cancel out". The term eventually gave rise to "blank", which originally referred to something white or shining, and later took on the meaning of an empty or unfilled space. From this concept of emptiness or lack of content, "blanking" came to be used in the context of erasing or censuring information, as well as the act of losing one's train of thought or memory temporarily.
