根据给定系统参数计算稳定性叶瓣图，该程序计算效果较好，适合初学者使用。(stable_lobe calculation)

采用解析法绘制稳定性叶瓣图，构建转速与切削深度之间的关系曲线，为切削参数的合理选择避免发生颤振带来方便。(Analytical method is used to draw the stability leaflet diagram, and the relationship curve between the speed and the cutting depth is constructed, which is convenient for the reasonable selection
