Laser fine processing technology plays an irreplaceable role in the manufacture of aerospace complex components. At present, China’s laser fine manufacturing technology is still lagging behind Europe and the United States, so it is necessary to greatly improve the laser manufacturing capability and level of complex components in China’s aerospace industry.
The laser pointer precision manufacturing and intelligent robot team led by Professor Chang Xuexue of Xi’an Jiaotong University, is a team of precision manufacturing and intelligent robots for aerospace complex curved surfaces. Large-scale surface functional pattern manufacturing, aeroengine hot end parts functional pattern surface integrity manufacturing, aviation The requirements of six types of typical complex components such as engine ceramic core/blade repair and functional structure composite manufacturing, combined with the research advantages of the team in laser processing technology development, automation equipment manufacturing, optical and electromechanical collaborative control, etc., independently developed 6 types of complex components. Surface laser fine manufacturing process and series equipment will fill many gaps in China’s aerospace manufacturing field.
The team members explored the scientific mechanism of the action mechanism of laser parameters and beam scanning characteristics on typical materials. The combination of theoretical research and experimental research carried out laser beam path planning and high-speed scanning, equipment online monitoring and compensation, feature three-dimensional detection and recognition, Research on key technologies such as opto-mechanical cooperative control, and in-depth study of laser multi-parameter control mechanism. In addition, the method of beam scanning characteristic control strategy is also studied. The variation law of photoinduced characteristics of typical materials and its mechanism and removal mechanism are discussed.
The independent development of laser pointer manufacturing technology and equipment will solve the bottleneck of high-quality manufacturing technology on the surface of China’s aerospace components, break through the foreign technology blockade, and provide key manufacturing technology for the development of new spacecraft and aero-engines in China.
