摘要
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。
Plenty exact reliability data have been obtained via two years trace routine on 20 home made CNC power presses,which have helped building up CNC reliability data based on PowerBuilder and Sybase to analyse statistically in details failure positions,failure mode and causes and to point out weak link and potential shortcoming hence providing with basis for reliability analysis and design of CNC power press.
