Influence of Milling Strategies of Thin-walled Elements on Effectiveness of their Manufacturing

The paper presents an analysis of milling strategies influence of thin-walled elements made of aluminum alloy EN AW-2024 on effectiveness of their production. Two values were adopted as measures of the effectiveness: result of emerging deformation (after removal of samples from clamping fixture) and machining time. The three milling strategies i.e.: HPC, HPC combined with conventional finishing operation as well as HPC and HSC were analysed as a part of experimental study. Each combination was characterized by the different range of technological parameters that have directly impacted on manufacturing effectiveness. On the base of obtained results it has been noted that milling strategies have an impact on the values of emerging deformation. The best result was achieved for combination of HPC with conventional finishing operation. Despite relatively low efficiency, conventional operation application can have a practical use.
