The realization of products from materials with high properties generally involves very high energy consumption. Thus, in the research, it was considered to optimize the machining process by cutting of an aluminum bronze alloy, so as to obtain a reduction in energy consumption in correlation with the roughness of the machined surfaces. The research focused on the processing of a semi-finished product with a diameter of Ø = 20 mm made of aluminum bronze (C62300). In addition, in the research, the aim was to establish some correlations between the amount of power consumed and the quality of the surfaces processed by cutting. In this sense, the forces were measured in the 3 directions specific to the cutting process (; ; ) for 3 tools construction variants and power consumed. The results showed that, if a certain constructive variant of the cutting tool is used in the processing, a reduction of the power consumed to cutting can be obtained by approximately 30% and a reduction of the roughness of the processed surface by approximately 90-100%. Furthermore, following the statistical processing of the results, it was shown that it would be advisable to use, especially in roughing processes, the cutting tool variant that offers the greatest reduction in roughness and cutting power.
用具有高性能的材料制造产品通常涉及非常高的能源消耗。因此，在这项研究中，考虑通过切削铝青铜合金来优化加工工艺，以便在与加工表面粗糙度相关的情况下降低能源消耗。该研究聚焦于加工一种由铝青铜（C62300）制成的直径为Ø = 20 mm的半成品。此外，在该研究中，目标是建立所消耗功率与切削加工表面质量之间的一些关联。从这个意义上讲，针对3种刀具结构变体和所消耗的功率，在切削过程特定的3个方向（；；）上测量了力。结果表明，如果在加工中使用某种特定的切削刀具结构变体，可以使切削所消耗的功率降低约30%，加工表面的粗糙度降低约90 - 100%。此外，对结果进行统计处理后表明，尤其在粗加工过程中，宜使用能使粗糙度和切削功率降低幅度最大的切削刀具变体。
