文章根据轴端挠度计算公式讨论了主轴刚度对被加工孔的尺寸精度和位置精度的影响,得出下面几个结论:1.轴端柔度在圆周方向上是变化的;2.被加工孔的位置与传动力有关,孔的尺寸与切削力有关;3.从理论上回答了镗孔过程中“吃刀不均匀”现象发生的原因及其量的关系;文章最后提出了提高主轴静刚度的途径。图7幅、参考文献2种。
According to the calculation formula of shaft end deflection, the paper discusses the effect of spindle rigidity on the dimensional accuracy and position accuracy of the machined hole, and draws the following conclusions: 1. The shaft end flexibility changes in the circumferential direction; 2. The machined hole The position and transmission force, the hole size and cutting force; 3. In theory, the answer to the boring process, “eat uneven knife” phenomenon occurs and the relationship between the amount of the article; Finally, the paper put forward to improve the static stiffness of the spindle Way.
