“…The levels of milling parameters and MWCNTs' content include spindle speed (600, 1,400, 2,200, and 3,000 rpm), feed (0.1, 0.15, 0.2, and 0.25 mm/tooth), and MWCNTs' content (0 and 3.5 wt %). Depth of cut was considered constant due to its negligible effect reported by Farshbaf et al [7].…”

“…On the other hand, it has been proven that the particles of MWCNT can act as a lubricant to reduce the friction [18]. Thus, it can be concluded that the MWCNT particles act as a lubricant in the cutting area and reduce the friction between tool/workpiece and tool/chip [7]. Thus, the possibility of seizing chip to the tool tip reduces and results in lesser BUE and better surface finish.…”

“…Farshbaf Zinati et al [7] studied the machinability of PA 6/nano-calcium-carbonate and modeled it with neural network. Rajmohan et al [3] studied the surface roughness, surface morphology, and surface hardness in drilling of Al356/10SiC (Wt %) and hybrid composite of Al356/10SiC-3mica (wt%) with three different types of drills.…”

Nowadays, Manufacturers tend to use polymer nano-composites as raw material because of their high thermo-mechanical properties and strength to weight ratio. Due to production methods of nano-composites which result in simple cross-sections and rising demands for private products, the need for machining polymers has increased. In this study, the surface roughness of polyamide 6/multi-walled carbon nano-tube composite has been investigated after endmilling. The nano-composite samples were produced with 3.5 wt% of multi-walled carbon nano-tube by friction stir process. In order to ensure the quality of fabricated nanocomposites, X-ray diffraction and scanning electron microscopy were used to evaluate it. End-milling was conducted at different levels of spindle speed and feed per tooth on polyamide 6 (with and without multi-walled carbon nano-tube) to study the resulted surface roughness. Then, analysis of variance was conducted to evaluate the parameters' influence on surface roughness. Additionally, the optimal cutting parameters were determined by coupling artificial neural network and harmony search algorithm. Results reveal that surface quality increases with decrease of feed per tooth, and increase of spindle speed and carbon nano-tubes improve the surface quality.

“…We established that the mass flow rate for the organobentonite-filled nylon is significantly lower, while the modification has also a positive effect on other physical characteristics of the material. Several descriptions of the influence of organobentonite clay on the mechanical properties of nylon 6 can be found in the literature [21,22], or other nano-fillers (nano-CaCO 3 ) on the milling properties of polyamide [23], but there is no information on how it affects the laser machining of these composites.…”

The popular polycaprolactam (polyamide PA6), commonly referred to as nylon 6, widely used as a construction plastic, is not a typical material for micromachining by CO 2 laser vaporization. In this paper, we describe investigations of the pulsed CO 2 laser grooving of both the chemically pure and the organobentonite clay modified nylon 6. Our results indicate that doping of nylon 6 with nanoparticles of organophilized bentonite significantly improves the grooving ability, predictability of the process, and its quality. In order to determine the nature of the changes in the depth and width of the grooves as a function of the laser process parameters, theoretical modeling of the laser grooving of nylon was carried out. The basic parameters of the laser grooving process versus laser beam intensity, pulse repetition rate, scanning speed of the material and various compositions of the organophilized bentonite dopant are presented. Additionally, an example of a three-dimensional engraving/milling of tested materials as well as the impact of doping on the channel profile are examined. The modification of nylon 6 by appropriate doping with bentonite clay radically improves the quality of micromachining with a CO 2 laser.
