我国数控线切割机床电气控制柜大都是复旦型和抗无专型的专用电子计算机,该机由于制造工艺和电子元件(大都是由分立元件及小规模集成电路组成)等等因素的影响,致使性能不稳定和不可靠,因而经常出错,给正常使用和维修带来较大的困难。根据这种情况,利用单板计算机即微处理机取代原数控电气柜来控制机床 China’s CNC WEDM electrical control cabinet are mostly Fudan-type and non-special type of dedicated computer, the aircraft due to manufacturing processes and electronic components (mostly composed of discrete components and small-scale integrated circuits) and other factors, resulting in Performance is unstable and unreliable, so often mistakes, to the normal use and maintenance of greater difficulty. According to this situation, the use of single-board computers that replace the original CNC electrical cabinet to control the machine tool
