Abstract:
Equivalent ways commonly used in engineering works are not effective to estimate the reliability of tandem system based on L-M method.One modified L-M method is an important means to estimate the reliability of CNC lathes.A method of using two named confidence limits for the estimation is put forward.Fitting results of the sub-systems of CNC machine tools are estimated.And the scattered level of confidence limits facing the reliability matrix of sub-systems can be clearly seen.
Key words:  L-M method  CNC lathes  reliability evaluation  confidence limits  scattered level
