首先简介裂纹技术,然后从分析切削加工的原始基点和本来含义出发,寻找二者的结合点。研究结果表明:裂纹技术的理想应力场和工程理想应力场,既可作为切削过程优化设计的最佳目标,也可作为各种已有(或将产生的)特种加工方法优劣的衡量指标,特别是裂纹技术的核心要素——裂纹,为切削加工提供了一把天然的,无限锋利的切具,使研究理想切削成为可能。文中还进一步指出,在裂纹技术的理论指导下主动控制,干预传统切削加工过程中可能出现的裂纹的萌生和扩展,有许多待开拓的研究领地,其结果将对鳞刺的抑制,切屑的顺利流出和切削效率的提高起重要作用。
First of all, a brief introduction of crack technology, and then starting from the analysis of the original base point and the original meaning of cutting, looking for the combination of the two. The results show that the ideal stress field and ideal stress field of crack technology can both serve as the optimal target for optimal design of cutting process and also as a measure of the advantages and disadvantages of various existing (or to be produced) special machining methods. Especially the core element of crack technology - the crack, provides a natural and infinitely sharp cutting tool for cutting, making it possible to study the ideal cutting. It is further pointed out in the paper that there are many researching fields to be exploited under the guidance of the theory of crack technology, and the results will suppress the scale sting and the chip smoothly Outflow and cutting efficiency play an important role.
