利用压力反馈自动控制加工误差的方法,对于消除机床“偶然因素”对机床加工精度的影响,能取得较为满意的效果。文中提出的方法,虽然处于模拟试验阶段,但可以预见,这种方法如能应用于生产实际,利用专用机床和普通机床进行改造,可显著提高机床的加工精度和降低生产成本。 The method of using pressure feedback to automatically control the machining error can get more satisfactory results for eliminating the influence of “accidental factors” on the machining accuracy of the machine tool. Although the method proposed in this paper is in the stage of simulation experiment, it can be foreseen that this method can be applied to the actual production by using special machine tools and ordinary machine tools to transform, which can significantly improve the machining accuracy and reduce the production cost.
