The CAD/CAM System of FRP Pipes

The CAD/CAM system of FRP pipes based on Internet is an integrated manufacturing system, used to design and produce high-pressure and sand-filling FRP pipes. It has realized the integration of the whole production process, from choosing of raw materials to winding machine control. The network of the system adopts the client/server mode, and the software is developed under VC++ 6.0 environment based on Windows 2000. The function and realization of process design, structure design and winding pattern design of CAD software are introduced. The winding pattern and speed control models are built according to fibre winding theory, and the open-architecture CAM system is designed based on industrial computer and motion controller. Key technologies such as CAM system software design, accurate timing in Windows and signal processing of rotary encoder are introduced. Practices show that this system shortens the development period of FRP pipes, and improves efficiency of production and management greatly.
