In this study, the effect of multi-wall carbon nanotube (MWCNT) on machining damages and material removal mechanisms in electro-discharge machining (EDM) of carbon fiber reinforced epoxy resin (CFRE) was evaluated. Field-emission scanning electron microscopy (FE-SEM) was used to investigate the machined surface morphology and elemental analysis. The effect of MWCNT content, pulse current, and pulse-on time was investigated on machining damages such as delamination, hole taper, and machining char...

Fiber-reinforced composites/fiber-reinforced polymer is excellent material owning the performance of high strength, high toughness, light weight, good fatigue resistance and shock absorption, and strong designability. It has a wide range of application prospects. The reinforcing fiber makes the cutting of the composites far from easy. When machining of FRP, the high tool wear, defects on machined surface, and poor processing efficiency severely restrict its wide application. Exploring the cuttin...

In the present study, a novel framework is presented that models the transient interaction between cutting teeth of an arbitrary end mill geometry and a workpiece. In this framework, the workpiece geometry is modeled using a voxelized representation that is dynamically updated as material is locally removed by each tooth of the cutting tool. A ray casting approach was used to mimic the process of the cutting faces of the tool intersecting the workpiece material. This ray casting approach was use...

So far, many investigations have reported that Zr-based bulk metallic glasses (BMGs) could be precisely and flexibly shaped by electrical discharge machining (EDM). However, EDM induced crystallization and roughness is still a bottleneck. In this research, bench-mode electrochemical surface smoothing (ESS) in the NaCl-ethylene glycol (EG) electrolyte has been proposed to post-process the spark erosion treated Zr-based BMGs in order to solve the abovementioned problems. The utilization of the NaC...

Roller clinching is a variation of conventional clinching by using rotational tool movement. The joining quality of roller clinching is significantly affected by tooling geometries and motions. Considering the formation difference of joints at different locations, this paper investigated the deformation features of roller clinching of square joints and utilized multiple linear regression analysis to optimize the processing parameters. It was found that roller geometry has significant impact on t...

The high flexibility of die-less spinning has great potential for industrial applications. The severe wall thinning of die-less spinning can be suppressed using the ball-crown-shape roller (BCSR). However, the mechanical properties of the spun parts need to be investigated. In view of this, a truncated cone was formed by die-less spinning using the BCSR, and the mechanical performance and microstructure of the spun workpiece were investigated. The micro-hardness distribution on the spun cone was...

This work explores the improvement of operational decision-making in a Fast Fashion manufacturing company, considering the Industry 4.0 era. The segment requires agile and flexible decision-making techniques to guarantee the companies survival in a high variety environment of products and demand. The proposed approach was based on three stages. First, we suggested changes and improvements in the system to adapt it to the Industry 4.0 principles. Then, we proposed a Digital Twin (DT) focused on o...

Residual stresses on aluminum parts can be modified during heat treatments. During solution heat treatment, quenching, and aging, metallurgical transformations combined with thermal gradients lead to a modification of parts properties. Quench and aging treatments sensitivity of AA 7175 aluminum alloy components is addressed in this work. Samples have been subjected to various quenching and aging treatments to verify the actual effect of the treatment parameters on their residual stresses. After ...

The machining quality of array flow channels directly affects the performance of solid oxide fuel cells as they are the key structures on the metallic interconnects of these cells. Electrochemical machining (ECM) is an efficient and low-cost technology for fabricating array flow channels. In the conventional ECM method, the cathode tool is usually designed to have cavity structures above the ribs to avoid collisions between the tool and workpiece. These cavities provide a passage for stray curre...

In this study, the machining characteristics of pulse short arc milling (SEAM) Ti6Al4V alloy were studied. In this regard, the influence of SEAM parameters on the material removal rate (MRR), relative electrode wear ratio (REWR), and surface integrity of Ti6Al4V is studied. A wide variety of processing parameters, including different voltages, frequencies, duty cycles, flushing pressures, electrode rotation speeds, and electrode feed rates, are considered in the investigation. Scanning electron ...
