Non-woven materials are now widely used in car roof interior parts. Non-woven materials will produce a large amount of suspended fiber dust during the cutting process, making the working environment of employees extremely harsh. If it cannot be effectively controlled, it will seriously affect the physical and mental health of employees. The processing quality and parameter consistency of the workpiece are also restricted by various anisotropies of materials. The processing of automotive interior parts is to design special tools and molds according to the characteristics of the surface of the workpiece. The design process is complicated and the price is high. Therefore, the production technology of automotive roof interiors is in urgent need of breakthroughs. The robotic waterjet cutting technology can realize precise cutting of irregularly shaped workpieces as long as the corresponding control program is adjusted. The high degree of automation and flexibility of robotic waterjet cutting is an inevitable trend in the processing of automotive interior parts. The waterjet cutting station of the waterjet booster pump and the ABB six-degree-of-freedom joint robot prove that the system has stable performance, good workpiece cutting quality and high production efficiency, which is suitable for popularization and application.
