The paper presents simulation and experiment to analyze the thrust force and cutting heat of conventional drilling (CD) and ultrasonic vibration–assisted drilling (UAD) with different tool point angles. The HAAS vertical machining center combined with ultrasonic vibrating shank has been used to study the hole quality in drilling of Ti-6Al-4V material without cooling, including surface roughness, residual stress, exit burrs, and tool wear. Stimulation results show that the thrust force and cuttin...

In this paper, the new alloy material, zirconium-based bulk metallic glass (Zr41.2Ti13.8Cu12.5Ni10Be22.5), which is hard and brittle, was the research object. Since the process of wire-electrical discharge machining offers the advantage of processing hard and brittle conductive materials, the effects of discharge parameters on material removal rate, surface roughness, surface morphology, carbonization and crystallization have been studied by changing discharge voltage, peak current and pulse wid...

Reducing the contact time of a water droplet on non-wetting surfaces has great potential in the areas of self-cleaning and anti-icing, and gradually develops into a hot issue in the field of wettability surfaces. However, the existing literature on dynamic behavior of water drops impacting on superhydrophobic surfaces with various structural shapes is insufficient. Inspired by the microstructure of lotus leaf and rice leaf, dual-level and three-level structures on plane and convex surfaces were ...

This research studied the surface homogenization and morphology of a Ti-6Al-4V alloy using the longitudinal-torsional coupled ultrasonic vibration-assisted milling (UVAM) of a ball-end cutter, in which a method of continuous processing between the flat surface and the freeform surface connection was proposed. The cutting experiments compared the UVAM method with the conventional milling (CM) process by setting three parameters: the cutting speed, feeding rate, and depth of cut. The finished surf...

In the process of ultra-precision machining, the tool-setting accuracy of the micro-milling tool is limited by the tool diameter. The accuracy of tool setting decreases with the decrease of tool diameter, which becomes an important factor for restricting the accuracy of ultra-precision machining. Based on the imaging principle of digital in-line holography, an efficient and non-contacted method for tool setting was proposed for improving the accuracy of tool setting. Aiming at the imaging proble...

Due to the large reduction in workpiece size and tool size, the quality of the micro-milling surface has a greater impact on the product than that obtained by conventional milling. Since the typical two-dimensional surface roughness parameters can only partially reflect the state of the surface, a three-dimensional surface roughness evaluation system is proposed to characterize the micro-morphology of the micro-milling surface in this paper. The micro-milled surface was simulated by a non-Gaussi...

The hard and brittle nature of Zirconium-based metallic glass (Zr41.2Ti13.8Cu12.5Ni10Be22.5) makes it difficult to meet industrial requirements in mechanical processing. Therefore, the processing performance of WEDM of MG was studied by using the advantages of WEDM to process hard and brittle conductive materials in this paper. The effects of peak current, pulse width and voltage on material removal rate (MRR) and surface roughness (Ra) were investigated by orthogonal experiment. Analysis of var...

The micro-cutting deformation mechanism is an important research content in the micro-machining mechanism. Various physical phenomena in metal cutting, such as cutting force, cutting heat, tool wear and surface quality, are based on the cutting deformation process. In this paper, the micro-cutting test of oxygen-free copper (OFC) was carried out by using orthogonal cutting device to study the deformation behavior during the chip formation process. The results show that the ratio of chip thicknes...

The surface of the titanium alloy was blackened by a nanosecond pulsed laser, and two-dimensional and three-dimensional morphology observations and microstructure reflection measurements were performed by scanning electron microscopy (SEM), laser confocal scanning microscopy (LCSM) and microscopic angular resolution spectrometry (ARM). The effect of laser processing depth on reflectivity was studied by one-way filling scanning method. The results show that under different laser processing times,...

The T-shaped groove and the square-column microstructure of the aluminum alloy surface were constructed by EDM. It was found that the contact angle of the square column formed by the two processes can reach 147.62°, and the surface of the part exhibits high viscosity at the same time. Successfully achieved the preparation of highly viscous hydrophobic surfaces. At the same time, solutions of different PH were prepared to further characterize the chemical stability of the samples. It is found tha...
