“…Studies in the production of combined parts of molds [39,40] have shown that, during abrasive processing of two materials, metal and metal-polymer, a situation may arise when the metal-polymer may undergo temperature degradation. The fact is that, while processing a composite part consisting of a metal and a metal-polymer, it is the metal surface that is most often subjected to processing.…”

The additive manufacturing of metal parts takes up an increasing number of areas of mechanical engineering, but it still remains too expensive for mass use. Based on the experience in the production of combined metal-metal-polymer forming parts of molds, a new method for the production of composite parts from a metal shell filled with metal-polymer is proposed. As a basis for the study, strength calculations are given by the finite element method for the details of the exoskeleton and a sample of simplified geometry. Comparison of the strength characteristics of parts made of various materials and their combinations showed high strength characteristics of a composite part made of a metal shell and a metal-polymer filler. The metal-metal polymer composite part is distinguished not only by its high strength but also by a significantly lower cost, due to the reduction in the volume of 3D printing with metal. The problems of obtaining composite structures are also discussed. The main problem is the development of a metal-polymer casting technology. The process of filling a thin-walled shell with a metal-polymer causes difficulty.

The manufacturing accuracy of large-scale complex components determines the performance and quality of aircraft, ships, high-speed rail, and other equipment. High-precision 3D measurement plays a crucial role in ensuring manufacturing accuracy. At present, the existing measurement methods rely heavily on manual labor, which cannot satisfy the requirements of industry quality and efficiency. This paper introduces an integrated mobile robotic measurement system for the accurate and automatic 3D measurement of large-scale components with complex curved surfaces. The system consists of the mobile optical scanning measurement device, visual tracking device, and software platform, which can realize comprehensive and accurate data acquisition and stitching of large-scale complex components. The combination of visual tracking and 3D measurement based on the coordinated motion of the dual robot achieved the automatic data acquisition of large-scale complex components without sticking coded targets. Additionally, this paper also introduces a DeepMerge algorithm that combines local and global features of the point cloud, which effectively corrects the initial stitching error of the visual tracking system. The validity of the measurement system and method was shown by the measurement and stitching experiments on the surface of the vehicle nose, ensuring the accurate measurement of the robot’s wide range of motion.

“…Grinding direction has a great influence on grinding force, and the grinding force in the reverse grinding direction is small. Dai et al [15] established the temperature field model in the grinding process of wind turbine blade cup grinding wheel, calculated the surface grinding heat source model by calculating the material removal depth in the grinding process, and carried out numerical simulation under different grinding process parameters.…”

Key rotating parts such as integral blisks and blades of aero-engines are widely made of titanium alloys. Abrasive belt grinding is one of the effective methods to improve the surface integrity. However, the grinding process produces greater grinding force and higher Grinding temperature,which have an impact on surface quality. At present, the force-heat coupling relationship in the grinding process and its influence on surface quality have not been explored. In this paper, a titanium alloy belt experiment is carried out to detect the force and temperature in the grinding process, this paper explores the influence of the grinding process parameters on the grinding force and temperature, and analyzes the influence on surface integrity of the force and temperature in the grinding process. The results show that the decrease of the belt linear speed, the increase of the feed speed and the grinding depth leads to the increase of the grinding force, the decrease of the feed speed, the increase of the belt linear speed and the grinding depth cause the temperature to rise. The effect of grinding depth on grinding force and grinding temperature is the most significant. And High grinding force and grinding temperature will cause the surface quality to deteriorate and even more serious defects. However, when the maximum temperature of the grinding temperature field reaches above 120°C, the surface roughness of the workpiece decreases from 1.596μm to 1.093μm, and the height of the surface undulation is reduced from 32μm to 19μm. This paper provides a reference for improving the surface integrity of the grinding process.
