英文摘要: |
In order to improve the cutting stiffness ,the paper studies the vertical hydrostatic bearing in the slide when a ram is in feed process .The change of the oil film thickness on hydrostatic guide rail and the curve of the oil film thickness in various cutting forces are calculated and a relation model through theoretical analysis method is derived . The pressure field of the guide rail recess is simulated based on the finite volume method and demonstrated through experiments. The study is of vital theoretical significance for the improvement of machining accuracy of numerical control machines and the entire computer numerical control (CNC) equipment and provides valuable theoretical basis for the design of hydrostatic guide rail in engineering practice. |
