3.可控性好，成形精确。单脉冲冲压最小可控变形量0.035mm ，最大可控变形量数mm ，并可根据成形曲率来调整激光光斑尺寸，常用尺寸为2mm~10mm。
1. the forming pressure of sheet metal forming is high, reaching GPa. Therefore, the full plastic forming of sheet metal under high pressure can be realized to solve the springback problem of small curvature forming.
2. non contact stamping is particularly suitable for forming small curvature automobile panels with partial reverse deep drawing and bulging.
3. good controllability and accurate forming. The minimum controllable deformation of single pulse is 0.035mm, the maximum controllable deformation number is mm, and the laser spot size can be adjusted according to the shape curvature, and the size is 2mm~10mm.
4. sheet metal processing has strong adaptability and high surface quality. The surface quality requirement before sheet metal forming is lower than that of conventional sheet metal stamping process. The surface roughness after forming is increased by 1~2 orders of magnitude.
The 5. sets of materials are reinforced and formed on the surface, forming a high residual compressive stress on the surface of the sheet metal workpiece, which is especially suitable for parts with the requirements of anti fatigue and stress corrosion.
6. sheet metal processing expands the scope of cold stamping parts, making high strength structural steel, titanium alloy, composite material and other materials can be formed, drawing and leveling.
