切削加工中切屑流向的预报是通过流屑角的计算完成的．本文基于Stabler法则和等效刀刃思想，综合考虑了刀具的前角、刃倾角、主偏角、刀片相邻刃设计夹角、刀尖圆弧半径、进给量、切削深度以及被加工材料性质等八个因素建立了计算机求解流屑角的数学模型．并以此分析了以上因素对流屑角的影响规律． The prediction of chip flow in cutting is done by calculating the chip flow angle. Based on the Stabler rule and the equivalent blade idea, this paper considers the rake angle, cutting edge angle, the main angle of the tool, the included angle of the adjacent blade, the arc radius of the tool tip, the feed rate, the cutting depth and the nature of the material being processed And other eight factors to establish a mathematical model of computer chip angle solution. Based on this, the influence of the above factors on the shedding angle is analyzed.
