Verification and Analysis on the Performance of AWE Gantry Milling Machine Columns

To determine the design performance of the new type of strong cutting milling machine column, by analyzing the extreme working conditions of the crossbeam and milling head during processing, the ideal connection constraint assumption method is adopted to simplify the machine tool model, calculate the force situation of the column under various working conditions. Then, the finite element analysis software AWE is used to perform the statics analysis on the column, extract the overall, X, Y, and Z deformation data of the column, and to obtain the maximum deformation difference of the uprights at the limit position. Finally, the degree to which the anisotropic deformation of the column in various directions affects the geometric accuracy of the machine tool is analyzed so as to determine whether the structural dimension design of the machine tool column can meet the cutting requirements.
