Cutting forces during milling of vertical thin-walled structures of aerospace alloys

The article presents the results of the experiment conducted under controlled cutting conditions with a constant material removal rate, an increased cross-section of the cutting layer was used, tested for use in finishing.The analysis examined the influence of input factors on the measured values.Samples with a thin wall in vertical orientation were made of two materials -titanium Ti6Al4V and nickel alloy Inconel 625, which were the first input factor.Additional variable factors adopted during machining were cutting tools (a general purpose tool, a tool for efficient machining, a tool for high-speed machining) and machining strategies (side face milling and cylindrical side milling).The prepared samples contain two machined surfaces -inputs and outputs.During machining, the signal of cutting force components was recorded for them, based on which their graphs were made.In the case of side face milling of nickel alloy, an approximately 50% increase in the Fx component and an approximately twofold increase in the Fy and Fz components is observed compared to their titanium alloy counterparts.When milling titanium alloy samples, the values of the cutting force components between the strategies were similar, whereas for nickel alloy samples, milling with general-purpose and performance tools resulted in the cutting force component Fx being half as large as for the frontal approach.
