For domestic manufacturing enterprises, improving product manufacturing process capability is an important method to form their core competitiveness. In the simulation experiment platform TURN5DOE, using the design of experiment method and Minitab software, the singlepoint lathe turning operation of the bronze bushing was simulated, the data sampling experiment was carried out; with the diameter and surface roughness as the experiment index, the cutting fluid, machine, nose radius, feed rate, and cutting speed were taken as the influencing factors to design an orthogonal experiment scheme. The optimum combination of the parameters is obtained through simulation experiments, to improve the stability and production capacity of production control system of enterprise.
