The Qualification Test Design of Reliability Based on EDM

摘要：

　　The failure data of electrical discharge machine(EDM)obey weibull distribution.With the mean time between failures(MTBF) as test index,the produce-side risks,user-side risks,identification ratio,MTBF expectation value and shape parameter as known parameter,we design EDM reliability qualification test.For the test requirements that just need to determine the machine reliability and minimize test time and cost,we choose sequential test method.For the shortcoming that sequential test cant end of self when the reliability of the machine tool is at a moderate level,we have to improve and perfect it and we propose the truncated sequential test method.Based on EDM,we compute the receive and reject conditions,censoring time,number of failures of the specific scheme.
