Structural design and analysis of micro milling machine tool

This article proposed the structural design of micro milling machine tool, three design schemes have been protocoled according to the design parameters. The third scheme has been chosen by comparing the structure and function, static structure and dynamic characteristics, which is a gantry milling machine tool and realizes multi-axis and multi-functional micro milling. Then the static and dynamic characteristics of gantry were analyzed by ANSYS software. Static and structural analysis results: the maximum deformation is 0.6μm, the maximum equivalent stress is 0.27MPa, it has good static structural characteristics. Modal analysis results: get the first six natural frequencies and mode of vibration of gantry and the column swinging is the main vibration mode type. Using orthogonal experiment method to optimize the column, reducing the total deformation. All the results can provide reference for actual processing in the future.
