问题的提出 当前数控机床正向多样化、多层次方向发展。由于近几年我国机床行业处于低谷,购买力低,使经济型数控机床成为数控机床的主流产品。目前几乎所有的机床厂都有经济型数控机床产品。但是经济型数控机床多数存在以下几个问题: (1)数控系统的可靠性与稳定性问题。国内生产的经济型数控机床,多采用国产数控系统。目前国产数控系统,从功能和技术上已不落后于国外先进的数控系统,但由于系统选用的元器件及系统布线的问题,使系统可靠性及稳定性普遍较差,主要表现在抗干扰能力差,经常会由于干扰出现误动作。
Problems raised At present, CNC machine tools are diversified, multi-level direction. In recent years, China’s machine tool industry at a low ebb, purchasing power is low, so that economic CNC machine tools become the mainstream of CNC machine tools. At present, almost all machine tool plants have economical CNC machine tools. However, the majority of economic CNC machine tools have the following problems: (1) CNC system reliability and stability issues. Domestic production of economic CNC machine tools, use more domestic CNC system. At present, the domestic CNC system does not lag behind the advanced CNC system in function and technology. However, due to the system components and system cabling problems, the system reliability and stability are generally poor, mainly in the anti-interference ability Poor, often due to disturbances appear misoperation.
