Experimental Study on Optimization of Ultrasonic Assisted Process Parameters for GH4169 Alloy
GH4169 high-temperature alloy has extremely high hardness and strength under normal and high temper-ature conditions.The thermal softening effect of conventional metal cutting is not obvious.At the same time,due to the low thermal conductivity and obvious work hardening of the material,traditional CNC machining methods have problems such as tool wear and low machining efficiency.Therefore,in order to achieve high-quality and efficient processing of high-tem-perature alloys.Comparative experiments are conducted on the mechanical response of conventional milling and ultrasonic testing under different processing parameters,and the tool wear experiments of conventional milling and ultrasonic assisted milling under the same working condition are analyzed.The influence of different processing parameters on milling force and the advantages of ultrasonic assisted milling over conventional milling in the side milling process are revealed.
