Vibration assisted machining is becoming a potential machining process for difficult-to-cut materials in aerospace and biomedical applications. This book presents the fundamentals, modelling and applications of vibration assisted machining process. It provides investigations on cutting forces, temperature, cutting stability, surface topography, microstructure evolution and tool wear in vibration assisted machining. Three representative regimes (i.e., ultrasonically assisted machining, modulation assisted machining and elliptical vibration machining) are investigated in this book. The systematic and in-depth research in this process will provide important theoretical and practical reference for researchers and engineers in relative fields.
