| 摘 要： | 用2种不同牌号和不同槽型的硬质合金刀具分别对优质中碳钢45#和GCr15轴承套进行切削实验，通过应用金属切削原理结合加工经济学分析方法，对零部件的可切削性对生产效率、生产成本的作用机制进行研究，从而揭示其对后两者的影响规律性；通过切削实验，探究刀具使用寿命、工件可切削性系数和整体硬度的内在联系。研究表明:当工件可切削性系数提高、刀具使用寿命延长以及工件硬度降低时，其加工成本将呈指数化降低，同时生产效率也会成倍提高。研究获得刀具使用寿命与加工经济性的量化关系曲线，从而实现切削过程最优化的可量化目标。研究数据和研究方法可为切削过程优化、刀具设计与优选提供方法和数据支撑。

| Abstract: | The cutting experiments of high quality medium carbon steel 45# and GCr15 bearing sleeve are conducted using two kinds of carbide cutting inserts with different grades and different groove profile.According to the metal cutting principle and analytical method of processing economics, the action mechanism of machinability of parts to production efficiency and production cost is studied with the goal of revealing the regular.Then the inner link of insert service life, machinability coefficient of work-piece and global hardness is explored through cutting experiments.The researches show that the processing costs will be indexed reduce as the improvement of machinability coefficient, insert service life lengthening and drop of work-piece hardness;meanwhile, the production efficiency will get doubled.In the research process, the quantitative relation curve between insert service life and processing economy is obtained to implement the quantifiable objectives of cutting process optimization.The research data and methods can provide methods and data support for the optimization of cutting process and tool design. |
