数控机床除采用硬件抗干扰措施外,对经济型数控机床或一类程控机械,还可采用软件抗干扰,因为它们的软件并不复杂,具有占空间小、信息量少、速度要求低、顺序性强、呈周期性的特点,因而,借助软件的丰富性和灵活性,用冗余软件来提高顺穿控制的可靠性和容错性是可能的,我们通过实践证明软件抗干扰是简单易行而富科学性。在参加连云港机床厂的 GZ7125型全自动高效弓锯床的微机改造的试制工作中,应 In addition to the use of CNC machine tool hardware anti-jamming measures, the economy of CNC machine tools or a class of program-controlled machinery, software anti-jamming can also be used, because their software is not complicated, with less space, less information, low speed requirements, order Therefore, with the richness and flexibility of the software, it is possible to improve the reliability and fault tolerance of the run-through control with redundant software. It is proved that the anti-interference of the software is simple and easy by practice And rich in science. In Lianyungang Machine Tool Plant to participate in the GZ7125 fully automatic bow saw efficient computerized transformation of the trial work, should
