DOI: 10.1177/0954405419875346
Abstract: Weak-stiffness structures are difficult to be machined because of their low stiffness, large deformation and poor stability through conventional machining. Ultrasonic-assisted machining has the superiority of reducing cutting force and increasing stiffness, which can result… read more here.
