摘要
金属切削过程中,刀具参与切削部分的最佳几何结构,对零部件的高品质加工、生产效率的提升以及刀具使用寿命的增加等方面均具有重要的影响。本文通过对可转位车刀片自身的几何结构(如:刀片外形、刀片厚度T_h、刀尖圆弧半径r及断屑槽形式等)和刀体综合几何结构(如:工作角度和紧固方式)两方面进行分析,提出了高性能可转位车削刀具结构设计的工程技术方法。研究可为新型可转位车削刀具的设计提供借鉴。
The optimal geometry of the working part of the cutting tool has an important influence on aspects such as high quality parts processing, improvement of production efficiency and the longer tool life in the cutting process. The geometric structure of index-able inserts （ such as ： the insert profile, the insert＇ s thickness Th, the tool radius r and the types of the chip breaking groove and so on） and the integrated geometric structure of cutter body （such as： the working angle and the fastening way） were analyzed in this paper, then the structural design engineering technique of high performance index-able turning tool was put forward. This conclusion serves as both data and technical support for the design of new index-able tools.
