Abstract: In order to overcome the problem that the traditional method is difficult to accurately analyse the relationship between friction force and material wear because it does not consider the stress of the valve sleeve material, a new simulation method for the material wear limit of the valve sleeve of the hydraulic reversing valve for five-axis CNC machine tool is designed. Based on the analysis of the force principle of the sleeve of the slide valve, the pressure on the sleeve material of the reversing slide valve was deduced. Then, the limit force and friction and wear mechanism of the material were simulated from three aspects of contact, friction and wear, and it was found that the material wear reached the limit when the friction coefficient reached 0.65. Experimental results show that the simulation time of this method is only 4.29 min, and the wear limit parameter error is always below 0.05.

Keywords: five-axis CNC machine tool; hydraulic reversing slide valve; valve sleeve material wear; limit numerical simulation; stress condition.
