Research on Reliability Distribution Technology of CNC Lathe HTC2050

Abstract

Abstract： By studying the reliability distribution of CNC lathe, it is possible to solve the problem of poor reliability and short life of CNC lathe, which can also reveal the weak links, key elements and components in the system design. The mathematical model of NC lathe is established by using Arlins distribution method, and the importance degree of each subsystem in CNC lathe is analyzed quantitatively based on the reliability allocation criterion. The reliability of all subsystems in the mechanical system and the feasibility of the Arlins distribution method are verified by an example.
