This paper discusses the problem of automatic lathe management, and at the same time, the optimization of inspection interval and tool replacement strategy can be summarized as an optimization problem with the least expected loss of individual parts and an effective algorithm is provided. For problem one, the inspection interval τ0 = 18, The tool change interval τ1 = 34 2, the expected loss of the corresponding single part C = 4.75 yuan, the optimal solution, and the Monte Carlo simulation results of the results for the second problem, check the interval τ0 = 1 1, Periodic tool change interval τ1 = 2 4 2, Expected loss cost of single part C = 7.22 yuan. For the third problem, we adopt a new improvement program to reduce the expected loss of individual parts to 5.34 yuan.This paper also checks the variable interval, the parameters Sensitivity, error analysis, etc. were discussed.
