Reliability Evaluation of Chain-type Tool Magazine and ATC

摘要：

　　As the tool magazine and automatic tool changer (ATC) are the important function units to reserve and change tools for the machining center,the tool-changing rate affects their reliability life which directly influences the performance level of the machining center.However,the reliability of the tool magazine and ATC has not yet got a reasonable evaluation index.Directing at the features of the tool magazine and ATC system,the mean tool change numbers between failures evaluation index is proposed,which is used to calculate the mean time to repair and estimate the collected failure data of the chain-type tool magazine and ATC.It can be seen that the tool magazine with continuous tool-changing adopts the mean tool change numbers between failures as the reliability evaluation index.
