【摘要】：数控技术是各种先进制造技术的基石,而国产数控机床还存在诸多问题,如生产效率低、精度低等缺点,与国外的数控机床之间存在着很大的差距。这种情况对于我国的数控产业发展不利。而随着计算机处理器速度的提高,它使得原先在数控系统中只能由硬件来实现的功能能够通过软件来实现。数控系统的软件在很大的程度上决定了数控系统的工作效率、工作方式、可靠性及开放程度。因此,对数控系统软件的研究就显得尤为重要。本文在实验室目前正在研发的硬件平台上研究开发基于嵌入式的数控系统软件,对其进行了总体设计,介绍其软件开发模式,对软件的任务进行分解规划,将其分为管理部分和控制部分。具体内容涉及数控系统管理部分人机交互界面各层次的设计与实现,包括具体的程序显示画面、位置显示画面、信息显示画面、帮助画面等的具体实现;控制部分译码模块的实现,包括数控程序的分析检错、译码模块的调用与实现、分别从长度补偿和半径补偿进行研究,并提出了一种五轴刀具补偿算法;此外研究开发了通信软件,将机与机床间的网口通信和串口通信集成到一个软件中,克服了通信方式的单一性,便于用户根据不同情况选择不同的通信方式。本文研究开发的基于嵌入式的开放式数控系统在自主研发的加工中心上进行测试,证明具有强大的功能性、灵活的适应性和良好的开放性。
[Abstract]:The numerical control technology is the cornerstone of a variety of advanced manufacturing technology, and domestic CNC machine tools still exist many problems, such as low production efficiency, low precision, there is a big gap between the foreign and the CNC machine tool. This kind of situation for our NC industry development disadvantage. With the computer processor speed, it makes the original only in the the NC system hardware to achieve the function can be realized through software. The CNC system software of CNC system determines the work efficiency, to a great extent work, reliability and openness. Because of this, the research of CNC system software is particularly important.
Based on the hardware platform that the laboratory is developing now, we develop the embedded CNC system software, design it, introduce its software development mode, decompose the task of software, divide it into management part and control part.
The specific content involves the design and implementation of each level of CNC system management interface, including specific program display, location display, information display, realization of the help screen; realize the control part of the decoding module, including error analysis of NC program, and realize the decoding module, the research was conducted from the length and radius offset, and put forward a kind of five axis tool compensation algorithm; moreover the research and development of the communication software, the integration of communication and serial communication network between the machine and the machine into a software, the single communication way, convenient for users according to the different situation of different modes of communication.
The open CNC system based on embedded system is tested on the self-developed machining center. It proves that it has strong function, flexible adaptability and good openness.
