Abstract:
The drilling assisted by ultrasonic elliptical vibration (UEV) is proposed in present paper. The drilling system assisted by UEV was developed. The characteristics of the drilling process assisted by UEV are analyzed. The effect of ultrasonic elliptical vibration on the axial drilling force, the radial drilling force and the chip thickness are investigated experimentally. The experimental results show that the axial drilling force, the variation of the radial drilling force and the chip thickness of drilling assisted by UEV can be reduced.

Abstract:
When difficult-to-machine materials are drilled, chips are produced, and these chips are difficult to control during the drilling process. Due to the limitations of conventional drilling, materials are drilled by ultrasonic-vibration-assisted technology. In this paper, the kinematics of ultrasonic-vibration-assisted drilling are first analyzed and the relevant equations are established. The characteristic thicknesses of chips are then studied, and the drilling paths for different phases and thicknesses of the chips are analyzed. The condition of complete geometric chipbreaking in the ultrasoni

Abstract:
Ultrasonic-assisted jet electrochemical micro drilling is an advanced variant of electrochemical machining to drill micro holes quickly and efficiently. The present article deals with the modelling and simulation of the integration of ultrasonic vibration with the conventional jet electrochemical micro drilling process. Multi-physics-based modelling and simulation approach has been used in the present work. The flow pattern of electrolyte jet was analysed for both jet electrochemical micro drilling and ultrasonic-assisted jet electrochemical micro drilling processes. The simulation results wer

Abstract:
A drill processing for the difficult to cut material such as ceramics, hardened steel, glass and heat-resistant steel is widely requested in the industrial world. Furthermore the drilling process becomes more and more difficult in the case of that the requested hole diameter is less than one millimeter. In order to achieve requirements for drilling process, ultrasonically assisted machining is applicable. Ultrasonic vibration assisted machining techniques are suitable to machine difficult-to-cut materials precisely. The ultrasonic vibration assisted sub-millimeter drilling process reduces the

Abstract:
AbstractRegarding drilling, ultrasonic-assistance enables various potentials such as less tool wear, enhanced chip breaking and burr reduction. Although there are many technological studies verifying these advantages, no theory for process behaviour, design and parameter evaluation is available. Thus, this paper presents a kinematic analysis of the interaction between tool and workpiece to contribute to overall process understanding. Specific process scenarios are classified and characteristic parameters for the evaluation and design of ultrasonic-assisted drilling are determined. In addition,

Abstract:
The origin of drilling force in drilling with twist drill is quite complicated owning to the complex shape of the drill bit cutting edges. In this paper, the drilling experiments both with and without the ultrasonic were designed and conducted on aluminum alloy with pre-drilled hole. The drilling force was tested and the different effects between the cutting edges of the twist drill on the drilling force were analyzed under various drilling parameters including the spindle speed, feed rate and vibration amplitude.

Abstract:
Sapphire is an attractive engineering material for the cover glass of smartphones and wristwatches because of its high hardness and resistance to corrosion, wear, and heat. However, the high rate of tool wear and brittle chippings around the holes are serious problems associated with drilling sapphire. To enhance the accuracy and efficiency of the drilling process on sapphire, this paper presents a novel tool-path strategy using helical milling along with various tool path patterns. Experimental results show that the proposed method successfully reduces brittle chippings around the holes.
