“…Zhang researched the relationship between stress characteristics and cracks propagation directions based on a varied cutting-depth nanoscratching test [17], he also discussed the transition of material removal mode based on the observation of scratched grooves. In another research of Zhang, the differences of material removal in conventional grinding and ultrasonic vibration assisted grinding (UVAG) were investigated by observing machined surface morphologies by using atomic force microscope (AFM) and scanning electron microscope (SEM) [18]. He also compared the scratched grooves width and cracks propagation of varied scratching depth by conducting actual experiments and simulating scratching process [19].…”

Because of the changes in cutting conditions and ultrasonic vibration status, the proportion of multiple material removal modes are of uncertainty and complexity in ultrasonic vibration-assisted grinding of optical glass. Knowledge of the effect of machined surface composition is the basis for better understanding the influence mechanisms of surface roughness, and also is the key to control the surface composition and surface quality. In the present work, 32 sets of experiments of ultrasonic vibration-assisted grinding of BK7 optical glass were carried out, the machined surface morphologies were observed, and the influence law of machining parameters on the proportion of different material removal was investigated. Based on the above research, the effect of surface composition was briefly summarized. The results indicated that the increasing of spindle rotation speed, the decreasing of feed rate and grinding depth can improve the proportion of ductile removal. The introduction of ultrasonic vibration can highly restrain the powdering removal, and increase the proportion of ductile removal. Grinding depth has a dominant positive effect on the surface roughness, whereas the spindle rotation speed and ultrasonic amplitude both have negative effect, which was caused by the reduction of brittle fracture removal.

Abstract. The removal mechanism of machinable ceramics in turning was studied, and a theoretical model of cutting force based on energy theory was proposed. Based on the turning test of machinable ceramics and kinematics analysis of the tool-workpiece system, a model of tool-workpiece contact zone considering the tool tip arc radius was established. The crack propagation path and three stages of the crack development were analyzed from the stress perspective. Then the energy of the crack system was studied, and the brittle fracture energy which is more suitable for brittle materials was put forward. Based on the principle of energy conservation, a correction theoretical model of cutting force was established, which was verified by turning experiments of machinable ceramics. The results indicated that the predicted values of the model were in good agreement with the experimental values. Both theoretical model and experimental results demonstrated that the cutting force decreased as cutting speed increased, and increased as cutting depth and feed rate increased. This model enabled an in-depth understanding of the interaction action between the cutting tool and work materials involved in the turning of machinable ceramics.

“…VAM has been applied to several machining processes, including turning, milling, drilling, and grinding, for the processing of hard materials. Reported benefits include the following: reduction in machining forces [24][25][26][27]; improved surface finish and form accuracy [25,[28][29][30]; suppression of burr formation [23,28]; reduction of tool wear and extension of tool life [30][31][32]. In the turning process, vibration assistance is relatively easy to implement on the cutting tool as it is stationary.…”

Vibration-assisted machining (VAM) is an external energy assisted machining method to improve the material removal process by superimposing high frequency and small amplitude vibration onto tool or workpiece motion. VAM has been applied to several machining processes, including turning, drilling, grinding, and more recently milling, for the processing of hard-to-machine materials. This paper gives a critical review of vibration-assisted milling (VAMilling) research. The basic kinematic equations of 1D and 2D VAMilling are formulated and three typical tool-workpiece separation types are proposed. State-of-the-art on the principle and structural design of VAM systems are reviewed. The benefits and applications of VAMilling are discussed with emphasis on machining of hard-to-machine materials. Finally, the paper concludes with future possibilities for VAMilling.
