| 摘 要： | 以刀体上装有两个等边不等角六边形硬质合金可转位刀片的浅孔钻为例,用向量矩阵法分析了可转位浅孔钻的几何参数.根据浅孔钻的加工特征将其分成稳态和非稳态两个工作状态,将非稳态加工分为钻入五个阶段和钻出三个阶段,并分别对其相应的几何参数的计算建立了数学模型.为对浅孔钻进行进一步力学建模、对其所受切削力、切削热的研究,对浅孔钻结构的改进、使用等打下了必要的基础.

| Abstract: | Taking a drill with hexagonal carbide indexable inserts having equal sides and different included angle as an example,the authors analyzed the geometric parameters by using vector-matrix approach. According to the processing characteristics,the drilling process was divided into two wording states,i.e. steady state and non-steady state,while the non-steady state was further subdivided into five phases for drilling in and three phases for drilling out,and mathematical models were built up for these two proced... |
