What are the functions of marking workpieces?

The functions of workpiece marking are as follows:

1. Positioning and alignment: Workpiece marking is used to mark the position of machining and assembly on the workpiece, so as to ensure the correct positioning and alignment of the workpiece in the subsequent machining and assembly process. This is very important to ensure machining accuracy, product quality and assembly accuracy.

2. Cutting and cutting: in the fields of metal processing, woodworking, stone processing, etc. Workpiece marking is often used to mark the position and size to be cut and cut. By marking, workers can accurately guide the tool to the correct position, ensuring the accuracy and consistency of cutting and cutting.

3. Machining and assembly: During machining, welding and assembly, workpiece marks are used to guide machining and assembly operations. For example, in mechanical processing, workers will choose suitable tools and processes according to the marking, and carry out milling, drilling and other operations; When welding, the crossed line indicates the welding position and weld shape; In assembly, the docking and connection modes of parts can be marked by marking.

4. Quality control: The marking of workpieces can be used for quality control and inspection. Through marking, quality inspectors can quickly judge whether the size and shape of the workpiece meet the standard requirements, thus ensuring product quality.

5. Prevent mistakes: In mass production, different processes may be completed by different people. In order to avoid mistakes caused by misoperation or misunderstanding, workpiece marking can be used as a standardized guide to ensure that every operator can work according to the predetermined marking.

6. Design verification: In the product design stage, engineers usually mark the key dimensions and positions on the drawings, and use these marks on the actual workpieces during the manufacturing process. This design verification ensures the consistency of products from design to manufacturing and avoids the difference between design and actual manufacturing.

Generally speaking, workpiece marking plays an important role in manufacturing, processing and assembly, which can not only improve production efficiency and ensure product quality, but also help to reduce human errors and ensure the smooth progress of the production process.
