In modern manufacturing, metal sheet processing is an extremely important process. With the continuous advancement of science and technology, the emergence of new metal materials has brought new opportunities and challenges to this field. An in-depth analysis of the processing characteristics of these new materials is of key significance for improving the efficiency and quality of metal sheet processing.

New metal sheet materials, such as high-strength aluminum alloy and titanium alloy sheets, have unique physical and chemical properties, and their processing characteristics are significantly different from traditional metal sheets. Take high-strength aluminum alloy sheets as an example. It has a high strength-to-weight ratio, which makes it popular in aerospace, automobile manufacturing and other fields. However, this high strength also brings some challenges during processing. Its higher hardness and strength require greater cutting force and forming pressure during cutting and forming, and ordinary processing tools and molds are prone to wear and damage. For example, when using traditional milling processes to process high-strength aluminum alloy sheets, the tool wears significantly faster than when processing ordinary steel sheets, which requires tool replacement more frequently, increasing processing costs and time.

Titanium alloy sheets are famous for their excellent corrosion resistance and high temperature performance. However, its processing characteristics are more complex. The thermal conductivity of titanium alloy is poor. During the processing process, the heat is easily concentrated in the cutting area and difficult to dissipate, resulting in a sharp increase in cutting temperature. Excessive temperature will not only aggravate tool wear, but may also cause surface burns and microstructural changes in the titanium alloy sheet, affecting its mechanical properties and surface quality. For example, when laser cutting titanium alloy sheets, if effective cooling measures are not taken, obvious heat-affected zones will appear on the cutting edge, reducing the strength and toughness of the material.

The plastic deformation behavior of new sheet metal materials is also different from traditional materials. During the forming process of some new alloy sheets, the stress-strain curves exhibit nonlinear characteristics and have obvious anisotropy. This means that processing parameters need to be more accurately controlled during forming operations such as bending and stretching. For example, when bending a new type of magnesium alloy sheet, the bending angle limit and springback amount in different directions are greatly different. If you operate according to traditional processing experience, it is difficult to obtain a bending that meets the accuracy requirements. Bend parts.

In addition, the surface quality requirements of new metal sheet materials are also more stringent. Since they are often used in high-end manufacturing fields, such as precision components of electronic equipment, medical equipment, etc., even small surface scratches and roughness changes may affect the performance and service life of the product. During the processing process, how to avoid damage to the material surface has become a major challenge. For example, when using abrasive jetting to machine new types of sheet metal, the particle size, jet velocity and angle of the abrasive need to be finely tuned to remove material without damaging the integrity of the surface.

Faced with the processing characteristics of these new materials, the metal sheet processing industry is also constantly exploring and innovating processing technologies and processes. Develop new high-performance tool materials and coatings to improve the wear resistance and heat resistance of tools when processing new materials; adopt advanced cooling and lubrication technologies, such as minimum quantity lubrication, low-temperature cooling, etc., to effectively control the temperature during processing ; Develop intelligent processing equipment that can adjust processing parameters in real time according to material characteristics to improve processing accuracy and efficiency.

The processing characteristics of new metal sheet materials have brought many new research topics and practical challenges to the metal processing industry. Only by deeply understanding these characteristics and continuously innovating processing technologies and processes can we give full play to the advantages of new materials, promote the development of the metal sheet processing industry in a direction of higher precision, higher efficiency, and greener environmental protection, and meet the needs of modern high-end manufacturing industries for metals. Growing demand for thin sheet parts.
