【Abstract】 Based on the grinding process parameters and process of blade profile, the motion performance and grinding contact pressure of each coordinate axis of the machine tool are determined, and the optimized design and frequency analysis of the blade machining belt grinder are carried out.Using the RTCP algorithm and an independent algorithm structure mode for the transmission chain, establish a mathematical model for the shaft, a library of calculation methods for the workpiece transmission chain, and a library of calculation methods for the tool transmission chain.Test the servo speed of the designed machine tool, optimize the weak links of the machine tool structure, and meet the grinding requirements of blade profile and full feature profile.By studying the deformation of the X,Y,and Z axes through finite element analysis, the natural vibration frequencies of the first to sixth order of the six axis abrasive belt grinder are calculated, analyzed, and optimized, which improve the contour accuracy of blade grinding and achieve significant processing economic benefits.更多还原
