With the aim of providing scientific guidance for the application of diamond cutting tools to the machining of stone-plastic composite, this work presents results on the influence of tool geometry and cutting parameters on cutting forces and temperature during helical milling of stone–plastic composite with diamond cutters. Four factors—helical angle, spindle speed, feed rate, and cutting depth—were assessed using a response surface method. Mathematical models were developed and identified by verification testing to accurately predict changes in cutting forces and temperature during composite helical milling. Then, the significant contributions of each factor and of two-factor interactions were determined by analysis of variance, and the trends of cutting forces and temperature were studied using response surface methodology. The optimal conditions in terms of low cutting forces and temperature were determined to be a helical angle of 70°, cutting speed of 51.3 m/s, feed per tooth of 0.24 mm, and cutting depth of 0.5 mm. These parameters are proposed for use in the industrial production of stone–plastic composite material to improve machining efficiency.

为了为金刚石切削工具在石塑复合材料的加工中的应用提供科学指导，本研究介绍了在螺旋铣削石塑复合材料时，刀具几何形状和切削参数对切削力和温度的影响的结果。金刚石刀具。使用响应面法评估了四个因素-螺旋角，主轴转速，进给速度和切削深度。通过验证测试来开发和识别数学模型，以准确预测复合螺旋铣削过程中切削力和温度的变化。然后，通过方差分析确定每个因素和两因素相互作用的显着贡献，并使用响应面方法研究切削力和温度的趋势。在低切削力和温度方面的最佳条件确定为：螺旋角为70°，切削速度为51.3 m / s，每齿进给量为0.24 mm，切削深度为0.5 mm。建议将这些参数用于石塑复合材料的工业生产中，以提高加工效率。
