通过对 2 0台国产CNC压力机的故障数据进行了两年的跟踪记录 ,获得了较为丰富准确的CNC可靠性数据。基于PowerBuilder和Sybase建立了数控CNC可靠性数据库 ;对国产CNC压力机的故障部位、故障模式及故障原因进行了详细的统计分析 ,指出了其薄弱环节和潜在弱点 ,为CNC压力机进行可靠性分析和设计提供依据。
After 20 years of domestic CNC press failure data were tracked for two years to obtain a more accurate and accurate CNC reliability data. Based on PowerBuilder and Sybase, CNC CNC reliability database was established. The fault location, failure modes and failure causes of domestic CNC press were analyzed in detail. The weak links and potential weak points were pointed out. The reliability analysis of CNC press And design basis.
