Vibration-assisted machining (VAM) has been proposed for tens of years and attracts a lot of attentions due to its unique advantages on improving the machining quality of a range of materials, especially intractable materials like titanium and nickel alloys. VAM combines conventional machining (CM) with high-frequency, small-amplitude tool vibrations. This paper presents a customized tool designed for two-dimensional (2D) VAM and reveals its movement rules. A simplified surface generation model

All the influential parameters on theoretical surface roughness using the customized tool are analysed over a wide range of values. This paper provides the theoretical basis for the selection of suitable cutting parameters and vibration parameters before machining.
