The paper presents a mathematical model for calculating the cutting force when processing 20crmnti steel with the Sandvik CNMG 120408 16P25T tool. The stand based on the 16d25 machine is presented. It allows measuring the actual values of the spindle speed, longitudinal feed, cutting depth, and cutting force. The results are transmitted to the computer via the LTR-EU-8 workstation with galvanically isolated LTE modules and a synchronization interface. According to the test results, the obtained theoretical model has a deviation from the actual measurements of no more than 0.12%. It is shown that the calculation results provided by the leading tool manufacturers are expected to be overstated. The difference in cutting forces can be more than 1.5 times.

本文提出了一个数学模型，用于计算使用 Sandvik CNMG 120408 16P25T 刀具加工 20crmnti 钢时的切削力。展示了基于 16d25 机器的支架。它允许测量主轴转速、纵向进给、切削深度和切削力的实际值。结果通过具有电隔离 LTE 模块和同步接口的 LTR-EU-8 工作站传输到计算机。根据测试结果，得到的理论模型与实际测量值的偏差不超过0.12%。结果表明，领先工具制造商提供的计算结果可能被夸大了。切削力的差异可以超过1.5倍。
