%X To improve the reliability of machine tools, this paper analyzed failure data of assembly of machine tools deeply. It researched the method of established the model of assembly reliability by piecewise twofold Weibull model and the process of the parameter fitted by maximum likelihood, and proposed the development of maintenance alarm system on machine tools based on reliability analysis. It illuminated the process of theory design and the method of function block design on alarm system. The application of example about the alarm system demonstrates that it is very useful and available for maintenance of machine tools with this method.
