切削力建模对于理解铣削过程的机械行为具有重要意义。通过对切削力的理解，可以通过刀具寿命、表面光洁度、尺寸精度和加工时间来改进工艺。建立切削力模型的基础是切削力系数的收集方法，文献中主要有两种方法，均发生在全啮合条件下：直线方向开槽切削。未切削切屑的几何形状强烈依赖于刀具轨迹，特别是对于齿面铣削技术，切屑不会像开槽时那样呈现出重复和某种程度上不变的厚度轮廓。收集摆线铣削的切削力系数在很大程度上仍未被探索，这是本文的重点，特别是建立对不同刀具路径技术的切削参数和系数值的理解。研究发现，刀刀进给和刀刀速度匹配时，刀刀轨迹与刀刀轨迹之间的差异较大，基于刀刀几何条件的刀刀参数减小了刀刀进给和刀刀速度的差异，刀刀进给和刀刀速度匹配时，刀刀进给和刀刀速度的差异最大。此外，收集系数的方法在单槽和双槽摆线上得到的结果相似，都小于开槽试验得到的系数。
Cutting force modeling is of great importance to understanding the mechanistic behavior of the milling process. Through the understanding of cutting forces the potential for process improvement by way of tool life, surface finish, dimensional accuracy and machining time is opened. The basis for establishing cutting force models lies in the method of gathering cutting force coefficients, of which literature has two main approaches, both of which occur under full engagement: linear-direction slotting cuts. The geometry of the uncut chip has a strong dependency on the toolpath, particularly for trochoidal milling techniques, where the chips do not exhibit the repeating and somewhat invariant thickness profile that occurs in slotting. Gathering cutting force coefficients for trochoidal milling remains largely unexplored and is the focus of this paper, particularly to establish an understanding of cutting parameters and coefficient values among different toolpath techniques. It was found that matching the tool feed and speed between trochoidal and slotting toolpaths produces large differences, which are reduced when using slotting parameters based on trochoidal milling chip geometry conditions, with the closest agreement resulting from matching the maximum chip thicknesses. Furthermore, the method of gathering coefficients produces similar results between single and double flute trochoidal, which are both less than the coefficients resulting from slotting tests.
