作者明确指出,机床大件刚度研究应当为提高机床加工精度服务。为此,文中提出应首先找准其应改善刚度的部位,然后有效地提高该部位的刚度。采用“优化选择”不必拘泥于刚度绝对值而着重于诸方案的相对比较值,且通过在能反映事物本质的情况下,尽可能的简化大大地减少了科研工作量。因而该方法不仅有效,而且经济易行、经济效益很高。文章对该方法作了详细阐述并通过实例作了说明。图6幅,参考文献2种。
The author made it clear that the study of large machine rigidity should be to improve the machine tool machining accuracy. To this end, the article proposed that we should first identify the site should be to improve the stiffness, and then effectively improve the rigidity of the site. The use of “optimization options” focuses not on the absolute value of rigidity but rather on the relative comparisons of the alternatives, and as much as possible simplification of the research effort is greatly reduced by reflecting on the nature of things. Therefore, the method is not only effective, but also economical and economical with high economic benefits. The article elaborates the method and illustrates it through examples.
