The study investigates the problem of modeling cutting-force components through response surface methodology and reports the results of an investigation into the impact of machining parameters on the cutting mechanics of polymer-matrix composites. The novelty of this study is the modeling of cutting forces and the determination of mathematical models of these forces. The models describe the values of forces as a function of the milling parameters. In addition, the cutting resistance of the composites was determined. The influence of the material and rake angle of individual tools on the cutting force components was also determined. Measurements of the main (tangential) cutting force showed that, using large rake angles for uncoated carbide tools, one could obtain maximum force values that were similar to those obtained with polycrystalline diamond tools with a small rake angle. The results of the analysis of the tangential component of cutting resistance showed that, regardless of the rake angle, the values range from 140 N to 180 N. An analysis of the feed component of cutting resistance showed that the maximum values of this force ranged from 46 N to 133 N. The results showed that the highest values of the feed component of cutting resistance occurred during the machining of polymer composites with carbon fibers and that they were most affected by feed per tooth. It was also shown that the force models determined during milling with diamond insert tools had the highest coefficient of determination in the range of 0.90-0.99. The cutting resistance analysis showed that the values tested are in the range of 3.8 N/mm to 15.5 N/mm.
本研究通过响应面法研究了切削力分量建模问题，并报告了对加工参数对聚合物基复合材料切削力学影响的调查结果。本研究的新颖之处在于切削力建模以及这些力的数学模型的确定。这些模型将力的值描述为铣削参数的函数。此外，还测定了复合材料的切削阻力。还确定了单个刀具的材料和前角对切削力分量的影响。主（切向）切削力的测量结果表明，对于未涂层硬质合金刀具使用大前角时，可获得与小前角的聚晶金刚石刀具相似的最大力值。切削阻力切向分量的分析结果表明，无论前角如何，其值范围为140 N至180 N。切削阻力进给分量的分析表明，该力的最大值范围为46 N至133 N。结果表明，切削阻力进给分量的最高值出现在加工含碳纤维的聚合物复合材料过程中，并且它们受每齿进给量的影响最大。还表明，在用金刚石刀片刀具铣削过程中确定的力模型在0.90 - 0.99范围内具有最高的决定系数。切削阻力分析表明，测试值在3.8 N/mm至15.5 N/mm范围内。
