Simply put (machining) is to use mechanical equipment to process materials, cut materials, and process the required workpiece shape.

During the whole process, the shape, size, relative position and properties of the blank form qualified parts according to the pattern and size on the drawing, which is the machining technology.

Machining mainly includes manual processing and numerical control processing. Handicraft means that mechanical workers process various materials by manually operating milling machines, lathes, drilling machines, sawing machines and other mechanical equipment. It is suitable for manual processing of small batches and simple parts.

CNC machining center means that mechanical workers use CNC equipment for processing, including machining centers, turning and milling centers, electric wire cutting equipment, wire cutting machine tools, etc. Most of the processing sites adopt numerical control processing technology. In the Cartesian coordinate system, the position coordinates of the processed parts are converted into the program language through programming, and the CNC controller controls the axes of the CNC machine tool through the program language, and automatically picks up materials as needed to obtain finished parts. CNC machining, continuous processing of workpieces, suitable for processing a large number of parts with complex shapes.

A production process that changes the shape, size, position and nature of a product is called a finished or semi-finished product. It is the main body of the production process.

The process is divided into casting, forging, stamping, welding, machining, assembly and other processes. Mechanical manufacturing process generally refers to the sum of mechanical processing process and parts assembly process. Other processes are called auxiliary processes, such as transportation, storage, power supply, equipment maintenance, etc.
