摘　　要：刀库及ATC(自动换刀装置)的可靠性优劣存在多种制约因素,为真实描述其可靠性状态,开发了刀库及ATC可靠性检测系统。系统可以对刀库的换刀精度、换刀时间、油压、油温、电机温度、故障等运行信息进行智能检测和数据采集。综合考虑刀库的功能性和可靠性,并依据使用者和研究者的意见,确定了各制约因素的比重,进而构造系统可靠性评测模型。编写了基于MFC的评测软件,进行数据融合与分析评价,最终给使用者或研究者一个直观的刀库可靠性评分。该方法易于理解,弥补了刀库及ATC可靠性评测的不足。There are many restricting factors about the reliability of knife library and ATC（ automatic tool changer）,to describe the status of reliability,testing system of knife library and ATC reliability is developed. The system can detect intelligently,and record the data of precision,tool change time,oil pressure,oil temperature,motor temperature,breakdown,etc. comprehensive Considering the functionality and reliability of the knife library,and according to the users and the researchers＇ opinion,the proportion of the various constraints is determined,and the reliability evaluation model was established. The evaluation software is wrote based on the M FC,data integration,analysis and evaluation is carried out,and a performance score of knife library is gave to the user or the researchers finally. This method is easy to understand and make up for the deficiency of the knife library and the manipulator reliability evaluation.
