“…In addition to the tool wear criterion, the quality of the machined surface can also be considered a tool to measure the performance of cutting uids [44,45]. In xed machining conditions (cutting parameters, cutting tool materials), cutting uids that can provide better performance from the point of view of lubrication, cooling, and removing chip particles from the machining zone produce a better surface quality.…”

More than 70% of industrial lubricant waste releases into nature after a period of utilization without any ltration stage. Knowing environmental concerns and increasing regulations over pollution, the request to use risk-free lubricant is irrefutable. One of these lubricants is vegetable-based cutting uid (VBCF), which has recently attracted attention. The present work has tried to study the compatibility or incompatibility of VBCF with human health and provide a method for eliminating or reducing their potential risks. To achieve this goal, a study on one of the most known, destructive, and accessible microbes (Pseudomonas) in the workshop environment was performed. The results showed that Pseudomonas could multiply in solid and liquid mediums, and its colonies could quickly propagate in VBCF. Therefore, as a signi cant achievement in this study, unreinforced VBCF is not a suitable selection from a health point of view. Although these cutting uids are introduced as a compatible lubricant with humans and the environment, bacteria and mold can multiply swiftly without apparent alterations. It was also observed that using nanoparticles like copper-oxide with a speci c volume fraction (0.4%) could ght with the bio lm of Pseudomonas to destroy the colonies at the initial time of their formation. Scanning Electron Microscope (SEM) images and Energy-Dispersive X-ray spectroscopy (EDX) analysis also studied the machinability attributes. The machining tests indicated that the nano uid also greatly impacts the control of tool wear mechanisms and surface quality in A286 superalloy machining. 1-IntroductionSigni cant heat is produced during the machining of superalloys and other di cult-to-cut materials, drastically decreasing the tool life [1, 2]. Therefore, cutting uid (CF) is utilized to reduce the cutting temperature during the process [3, 4]. In general, cutting uid is applied to improve the e ciency and performance of cutting operations [5]. The main advantages of cutting uid application are reducing the heat, increasing tool life, improving surface nish, preventing adhered-chip formation on the tool face (especially in alloys of which adhesive wear is the dominant mechanism), and facilitating chip removal of the cutting area [6]. Though different CFs utilized in the machining industry, mineral-based cutting uids (MBCFs-approximately 85% of used oil) are the most widely used ones. Some scientists reported the worldwide consumption of 2.4 million tons of different cutting uids per year [7, 8]. Besides, the annual consumption of MBCFs in the European Union is around 320 thousand tons. Furthermore, more than twothirds of the used oils deliver to nature without a ltration process [9]. However, the use of cutting uids creates some di culties and limitations, including environmental issues, operator health problems, as well as high costs (purchase and maintenance) due to unstable crude oil derivatives (approximately 17% of the total cost of cutting processes) [10,11].In practice, all CFs utilized in machining industries are...

Traditionally, simulation studies in dentistry have relied on the finite element method (FEM). However, the smoothed particle hydrodynamics (SPH) method, which represents objects as particle collections without the use of meshes, has gained recent attention. Despite its application in dentistry, there is currently a lack of comprehensive literature summarizing the specific applications of the SPH method in the oral region. This review aims to provide a summary of studies that have utilized the SPH method in dentistry, focusing on its applications in analyzing large deformations, such as dental ceramic collisions, soft material analysis (e.g., denture adhesive), and virtual training simulations for dental treatments. By combining the advantages of the SPH and FEM methods, more accurate simulations can be achieved, and further applications of the SPH method in dentistry are anticipated.

“…In this study, the transient structural analysis was used as an alternative to the explicit dynamics method for simulating the scratch test to save time and minimize expenses. However, recent research has been actively exploring the application of a method using Smooth-Particle Hydrodynamics (SPH) coupled with the Finite Element Method (FEM) for grinding [28][29][30][31]. This method offers the advantages of time efficiency for slow behavior and the ability to simulate realistic behavior.…”

An Analysis of Edge Chipping in LiTaO3 Wafer Grinding Using a Scratch Test and FEA Simulation

Lithium tantalite (LiTaO3) is a representative multifunctional single-crystal material with electro-optical, acoustic, piezoelectric, pyroelectric, and nonlinear optical properties used as a substrate for surface acoustic wave (SAW) devices. To enhance SAW device performance, thinner LiTaO3 substrates with improved surface roughness are desired. Chemical mechanical polishing (CMP) is employed to achieve the desired surface roughness after grinding. However, the thinning process increases the risk of substrate fracture, especially at the edges, resulting in edge chipping. Edge chipping can lead to complete substrate failure during SAW device fabrication, requiring an effective wafer geometry to prevent it. The study utilizes scratch tests and finite element analysis (FEA) to identify the optimal edge shape (C-cut, trimmed, and thinned) for preventing edge chipping on LiTaO3 wafers. The C-cut edge refers to the rounding of the wafer’s edge, while the trimmed edge refers to the machining of the wafer’s edge to be perpendicular to the wafer surface. As a result of the scratch tests, we observed edge-chipping lengths of 115 and 227 μm on the C-cut and trimmed edges, respectively, while the thinned edge (half C-cut) resulted in complete wafer fracture. In the finite element analysis (FEA), edge-chipping lengths of 80, 120, and 150 μm were obtained on the C-cut, trimmed, and thinned edges (half C-cut), respectively. In conclusion, it has been confirmed that the C-cut, trimmed, and thinned edge shapes are effective in preventing edge chipping. However, considering that the C-cut edge shape becomes thinner through grinding, using the trimmed edge shape appears to be the most effective.
