In many machining operations, metalworking fluids (MWFs) play an invaluable role. Often, proper application of intelligent MWF strategy allows manufacturing processes to benefit from a multitude operational incentives, not least which are increased tool life, improved surface integrity and optimised chip handling. Despite these clearly positive implications, current strategies often unable acco...

Ti6Al4V alloy is one of the typical difficult-to-machine materials and often results in rapid tool wear, leading to poor machining quality aircraft assembling. Compared conventional helical milling, ultrasonic assistant milling (UAHM) process has indicated its superior performance; however, it still a great challenge improve hole surface accuracy. In addition, few studies have been conducted on...

The growing need to increase productivity and pressures for more sustainable manufacturing processes lead a shift less harmful lubrication systems that are nature the people involved. minimal quantity system (MQL) stands out in this respect, especially interrupted cutting such as milling, due interface’s highly dynamic chaotic nature. Using graphene sheets fluids also increases efficiency of ma...

In this current era of competitive machinery productions, the industries are designed to place more emphasis on the product quality and reduction of cost whilst abiding by the pollution-preventing policy. In attempting to delve into the concerns, the industries are aware that the effectiveness of existing lubrication systems must be improved to achieve power-efficient and pollutionpreventing ma...

Mixture-of-experts (MoE) models are a powerful paradigm for modeling of data arising from complex data generating processes (DGPs). In this article, we demonstrate how different MoE models can be constructed to approximate the underlying DGPs of arbitrary types of data. Due to the probabilistic nature of MoE models, we propose the maximum quasilikelihood (MQL) estimator as a method for estimati...

Cutting fluids can be used to cool workpieces at high cutting speeds and remove chips from zones. The effectiveness of may improved with the addition hybrid nanoparticle dispersion. This study evaluates an Al2O3-TiO2 as a fluid in turning operations. nano-cutting was prepared using one-step method computer numerical control (CNC) coolant concentrations up 4%. Utilizing air-assisted injected thr...

The influence of transverse surface roughness on EHL characteristics has been investigated numerically using an extensive set of full EHL line contact simulations for shear-thinning lubricants under pure sliding condition. The shear-thinning behavior of lubricant is modeled using Carreau viscosity equation along with Doolittle-Tait equation for lubricant compressibility. The surface roughness i...

The reduction of environmental burdens is required to mitigate global warming, ozone layer depletion and etc. in manufacturing fields. Hence, prediction system of environmental burden for machining operation has been developed based on LCA (Life Cycle Assessment) policy in this research. The prediction system can evaluate cutting conditions from the view points of environmental burden due to el...

Machining is the art of developing sustainable mechanical components by transforming solid raw materials into finished product. Because for any Nation to achieve development, must have quality manufacturing industries. This paper summarizes existing articles on effects high-pressure lubrication conditions chip formation and temperature distribution. Also, surface roughness, tool wear, vibration...
