Investigation and optimization of MQL system parameters in the roller-burnishing process of hardened steel
An-Le Van, Trung Thanh Nguyen
Izvirni znanstveni članek
Oznake: internal burnishing;cylindricity;circularity;roughness;
In the current study, the internal burnishing process under the minimum quantity lubrication (MQL) condition has been optimized to decrease the cylindricity (CYL) and circularity (CIC) of the burnished hole, while the surface roughness (SR) is predefined as a constraint. The optimizing inputs are th ...

Optimization of friction stir welding operation using optimal Taguchi-based ANFIS and genetic algorithm
An-Le Van, Trung Thanh Nguyen
Izvirni znanstveni članek
Oznake: friction stir welding;energy efficiency;jointing efficiency;micro-hardness;NCGA;
The friction stir welding (FSW) process is an effective approach to produce joints having superior quality. Unfortunately, most published investigations primarily addressed optimizing process parameters to boost product quality. In the current work, the FSW operation of the aluminum alloy has been c ...

Impacts of burnishing variables on the quality indicators in a single diamond burnishing operation
Minh-Thai Le, An-Le Van, Trung Thanh Nguyen
Izvirni znanstveni članek
Oznake: single diamond burnishing;average roughness;bayesian regularization;vickers hardness;NSGA-G;
Diamond burnishing is an effective solution to finish a surface. The purpose of the current work is to optimize parameter inputs, including the spindle speed (S), depth of penetration (D), feed rate (f), and diameter of tool-tip (DT) for improving the Vickers hardness (VH) and decreasing the average ...

Multi-performance optimization of the rotary turning operation for environmental and quality indicators
Tat-Khoa Doan, Trung Thanh Nguyen, An-Le Van
Izvirni znanstveni članek
Oznake: rotary turning;total energy consumption;surface roughness;noise emission;IQPSO;
In this investigation, two environmental metrics (the comprehensive energy used (TU) and turning noise (TN)) and a quality metric (surface roughness (SR)) of the rotary turning process for the Ti6Al4V were optimized and reduced using the optimal factors (the inclined angle-i, depth of cut-d, feed-f, ...

Multi-response optimization of GTAW process parameters in terms of energy efficiency and quality
An-Le Van, Thai-Chung Nguyen, Huu-Toan Bui, Xuan-Ba Dang, Trung Thanh Nguyen
Izvirni znanstveni članek
Oznake: GTAW;heat input;ultimate tensile strength;micro-hardness;radial basis function network;
This work optimizes the current (I), voltage (V), flow rate (F), and arc gap (G) of the gas tungsten arc welding (GTAW) of the Ti40A titanium alloy to decrease the heat input (HI) and improve the ultimate tensile strength (TS) and micro-hardness (MH). The radial basis function network (RBFN) was uti ...
