Method for designing CNC (computer numerical control) systems of numerical-control cutting machines

Abstract

The invention discloses a method for designing CNC (computer numerical control) systems of numerical-control cutting machines. The method includes designing hardware structures of the CNC systems and designing software structures of the CNC systems. The method has the advantages that the CNC systems designed by the aid of the method are developed in Windows interfaces and have all merits of Windows programs; limitation of 64 kB memories can be broken through, accordingly, a plurality of application programs can be simultaneously run, and keyboard and mouse window operation can be facilitated; graphics programming modules of the CNC systems are developed on the basis of AutoCADR12.0, whether machining programs and machining paths are correct or not and whether requirements of machining processes are met or not can be easily checked and judged by operators, and accordingly the machining programs and the machining paths can be timely modified; the CNC systems are universal to a certain extent, can be used for numerical-control flame cutting machines and also can be used as control systems for water jet cutting machine tools, laser cutting machine tools and the like after being slightly modified.

Description

technical field [0001] The invention relates to a method for developing a CNC system of a numerically controlled cutting machine in the field of mechanical processing and production, in particular to a method for designing the CNC system of a numerically controlled cutting machine. Background technique [0002] At present, the domestic CNC flame cutting machine CNC system mainly uses single-board computers, single-chip computers, and PCs below the DOS platform 386CPU. The operating system has low performance and functions, and it is very inconvenient to use; with the IPC With the improvement of machine performance and the reduction of price, the huge advantages of using IPC to develop CNC systems are gradually emerging; IPC has higher reliability and anti-interference ability, and has the same high operating speed and rich functions as PC. Hardware resources (CPU, memory, coprocessor, software and hardware drivers, serial / parallel ports, interrupts, timers, bus slots, displa...

[0002] At present, the domestic CNC flame cutting machine CNC system mainly uses single-board computers, single-chip computers, and PCs below the DOS platform 386CPU. The operating system has low performance and functions, and it is very inconvenient to use; with the IPC With the improvement of machine performance and the reduction of price, the huge advantages of using IPC to develop CNC systems are gradually emerging; IPC has higher reliability and anti-interference ability, and has the same high operating speed and rich functions as PC. Hardware resources (CPU, memory, coprocessor, software and hardware drivers, serial / parallel ports, interrupts, timers, bus slots, displays, keyboards, power supplies, etc.), software resources (Windows platform and various development software, such as AutoCAD, network communication, etc.) and function calls, has an open architecture and has a high performance-price ratio; as long as the self-developed or purchased drive system servo control card and I / O card, on the basis of fully developing and utilizing the inherent functions of the IPC machine, the self-developed control system software can make the IPC machine a CNC system capable of real-time multi-tasking processing, friendly interface and powerful functions; and, with With the continuous updating of IPC machines, the CNC system developed by it is also easy to update; therefore, it is necessary to develop a CNC system with good performance, complete functions, and convenient programming and operation. One is to control the old CNC flame cutting machine. The system is updated, and the second is to support the new CNC flame cutting machine
