Abstract


In this paper, a desktop micro - milling machine for micromachining programs , according to the program , a desktop micro - milling machine structure design and simulation analysis . Selection and design in this article on the key components of the micro milling ; CATIA software to three-dimensional modeling of small milling ; using ANSYS software for two-dimensional and three-dimensional static and dynamic finite element modeling of electric spindle ANSYS natural frequency the modal harmony response characteristics derived electric spindle static stiffness ; electric spindle ; electric spindle vibration mode and the critical speed ; , and high - speed electric spindle where the front-end , back-end , bearing the four positions as well as electric spindle central position of the maximum dynamic displacement is analyzed and calculated . Small milling machine bed first five modal finite element analysis, the bed and shapes .
