Standardization is another important aspect of measurement. It involves the use of standardized units or standards for comparison in other contexts. If measurements are not standardized, they are likely to be inaccurate, and it can be difficult to compare different values and share data.
Precision and accuracy are two of the most fundamental measurement objectives. Precision is the ability to obtain successive observations using the same methodology or in different cases, under the forex dataset same environmental circumstances. Accuracy, on the other hand, is defined as the proximity of the actual output or measured value to the correct or standard value. Accuracy and precision are preferred characteristics of measurement. They are essential in various disciplines, including scientific research, engineering, and general use.
EDM Wire cutting, also known as wire cutting or wire EDM, is a new process developed from electrical discharge machining technology. Traditional EDM . It is widely used in the production and development of new products to directly cut parts, which can improve production speed or shorten development cycles. This article introduces some aspects of wire EDM cutting to help you better understand this technique.
The basic principle of wire cutting is to use a continuously moving thin metal wire (usually molybdenum or copper) as an electrode. This wire produces pulsed spark discharges on the workpiece, which erodes the metal and forms the cut.
During cutting, pulsed discharges occur between the electrode wire and the workpiece. The wire connects to the negative terminal of a pulsed power supply, and the workpiece connects to the positive terminal. When a pulse voltage is applied, a spark discharge occurs, with temperatures exceeding 10,000°C in the center of the discharge channel. This high temperature melts and even vaporizes the metal, causing localized expansion and micro-explosions that eject molten and vaporized metal, enabling electrical erosion cutting.
Thread cutting classification
Wire cutting, or wire EDM, can be classified according to the speed of the electrode wire:
High-speed wire cutting (fast wire EDM)
Wire EDM machines with high-speed reciprocating wire movement (8-10 m/s).
Low speed wire cutting (slow wire EDM)
Wire EDM machines with unidirectional wire movement at low speed (0.2 m/s).
Medium speed wire EDM
