Experimental investigation on flank milling section of thin-wall plates with different tool inclination angles
As the core component of aero engine, compressor blade is hard to machine due to its thin-wall constitution and titanium alloy material.As for the finish milling of blade length, small amount of cutting is usually used by enterprises to avoid the severe blade vibration to acquire the required dimensional accuracy and surface quality, which affects the machining efficiency seriously.In order to solve this problem, this paper proposed a method for flank milling section surface of thin-wall part with the tool inclined to proper inclination angles.Through the design and development of flank milling experiments of thin-wall plate with different tool inclination angles,the effects of inclination angle on cutting forces and machined surface quality were studied under different axial depths of cut.Experimental results show that when tool inclination angle is between 10° and 20°, the vibration of thin-wall plate could be controlled effectively and then the machining efficiency could be improved with favorable machined surface quality.This work could provide beneficial guidance for the optimization of processing parameters and improvement of efficiency for blade machining.
