Machining, also known as mechanical machining, is a process that removes excess material from raw materials through methods such as cutting, grinding, or drilling to achieve the desired shape, size, and surface quality. This industry is widely used in various fields of manufacturing, including automobiles, aerospace, electronic equipment, and medical devices. This article will discuss in detail the purpose, methods, applications, and importance of machining in modern industry. I. Purpose of Machining

The main purpose of machining is to process raw materials (such as metals, plastics, wood, etc.) into parts or components with specific shapes, sizes, and precision. These parts are usually used to build more complex mechanical systems or products. Through machining, high-precision, high-quality, and high-efficiency production of parts can be achieved to meet the needs of various industrial applications.

II. Machining Methods

Machining includes a variety of methods, each with its specific application scenarios and advantages. The following are some common machining methods:

1. Turning: Turning is a method of removing material by rotating a cutting tool. This method is suitable for machining cylindrical, conical, and other rotating parts.
2. Milling: Milling is a method of removing material using a rotating cutting tool. By adjusting the relative position between the tool and the workpiece, various complex shapes such as planes, grooves, and gears can be machined.
3. Drilling: Drilling is a method of machining holes on a workpiece using a drill bit. Drilling can be used to machine holes of various diameters and depths to meet different application needs.
4. Grinding: Grinding is a method of removing material using an abrasive tool. This method is suitable for machining high-precision, high-surface-quality parts such as bearings and gears.
