|With the vigorous development of China’s aerospace manufacturing industry, high-precision, lightweight, large-size thin-walled structural parts have become the mainstream products in the field of space rockets manufacturing. However, during the machining process, the thin-walled structures for space rockets are more susceptible to generate squeal due to their weak rigidity characteristics, which can cause physical and psychological hazards to workers. In this paper, we discuss the causes and influencing factors of machining noise for thin-walled structures, and summarizes the methods to suppress noise from parameter setting, machining tool selection, tooling fixtures using, etc., with a view to providing solutions for the prevention and control of machining noise in industrial enterprises. On this basis, the research prospects of machining noise of composite components, the generation and prevention of grinding noise, and the design of noise-reducing tooling fixtures are prospected.
