Abstract

The invention discloses an NURBS curved surface interpolation based interpolation system and method. The system mainly comprises a PC (Personal Computer) or IPC (Industrial Personal Computer), an ARM (Advanced RISC Machines) microprocessor and five control units; the PC or IPC runs a Windows XP / Windows Server 2003 / Windows 7 system and is in the same Ethernet network as well as accesses the Internet at the same time with the ARM microprocessor; the control units control a cutter to move according to a cutter spacing coordinate calculated by the ARM microprocessor, and every control unit controls one coordinate direction; the PC or IPC and the ARM microprocessor are connected through a network cable and an RJ45 port as well as transmit data through a TCP (Transmission Control Protocol) / IP (Internet Protocol). The NURBS curved surface interpolation based interpolation system and method has the advantages of less data transmission requirements, high processing speed, smoothness and the like in the free-form curved surface processing.

Description

technical field [0001] The invention relates to an interpolation system and method based on NURBS curved surface interpolation, in particular to an interpolation system and method based on NURBS curved surface interpolation with remote design and simulation functions. Background technique [0002] The development of the manufacturing industry is inseparable from the numerical control system. The level of the CNC system actually represents the level of a country's manufacturing industry. In the numerical control system, the control system is its core component, which is similar to the human brain, controlling the tool to move according to the requirements, and process the shape that meets people's requirements. The traditional controller adopts a closed structure, and its core technology is controlled by several major CNC companies. The closed structure of the controller makes it expensive and difficult to improve, and it is difficult to integrate other advanced technologie...
