Vibration Mode Analysis of Casting Flash Cutting Machine

In allusion to the complex nonlinear vibration characteristics of the casting flash cutting machine, this paper was to analyze the vibration mode of the whole machine in the working process with the finite element software-ANSYS Workbench. It was found that the machine tool was severely deformed at the first, second and fifth frequencies. The excitation frequency of the machine tool had a certain difference from the 6th-order natural frequency value obtained from the modal analysis. It provided an effective theoretical basis for the vibration reduction control of the whole machine. At the same time, the deficiencies of the machine tool in the testing process were improved, and the machining accuracy, running stability and production efficiency of the casting flash cutting machine were achieved.
