Machining Simulation of Semi-open Integral Impeller Based on UG and VERICUT
In view of the difficulty of machining the impeller as a whole,this paper takes the multi-axis machining technology and programming of the semi-open impeller of the centrifugal pump as the design object.Based on the analysis of its structural characteristics,this paper formulates the machining technology,selects the appropriate equipment and tools for machining programming and simulation,and uses NX software to complete the tool track of the roughing and finishing of the impeller of the centrifugal pump.VERICUT simulation software was used to build DMU65 five-axis CNC machine tool to complete dynamic simulation machining.The experimental results show that the tool path trajectory gen-erated by the design can make the simulation machining overcut error less than 0.1mm and the residual error less than 0.12mm,which effectively improves the generation efficiency and machining quality,and provides a theoretical basis for the subsequent research of impeller machining.Meanwhile,the program determined by the simulation data has a certain theo-retical feasibility and reliability.
