“…Thus, the Taguchi’s experimental method was used to optimize the process parameters for fabricating PLA filaments with the desired diameter and high tensile strength. To investigate the effects of process parameters on the PLA filament diameter, Taguchi’s L 9 (3 4 ) orthogonal array [ 34 , 35 , 36 , 37 ] was employed to determine the signal-to-noise (S/N) ratio in this study. To determine the optimal process parameters for molding tensile test specimens with the desired diameter of 1.7 mm, nominal-the-best [ 38 ] was chosen since the FDM 3D printer can print physical models using the PLA filaments smoothly.…”

The amount of wasted polylactic acid (PLA) is increasing because 3D printing services are an increasingly popular offering in many fields. The PLA is widely employed in the fused deposition modeling (FDM) since it is an environmentally friendly polymer. However, failed prototypes or physical models can generate substantial waste. In this study, the feasibility of recycling PLA waste plastic and re-extruded it into new PLA filaments was investigated. An automatic PLA filament extruder was first developed for fabricating new PLA filaments. This paper also discusses the process, challenges, and benefits of recycling PLA waste plastic in an effort to fabricate new PLA filaments more sustainable. It was found that it was possible to fabricate PLA filament using recycled PLA waste plastic. The production cost is only 60% of the commercially available PLA filament. The tensile strength of the developed PLA filament is approximately 1.1 times that of the commercially available PLA filament. The design of experiments approach was employed to investigate the optimal process parameters for fabricating PLA filaments. The most important control factor affecting the diameter of PLA filament is the barrel temperature, followed by recycled material addition ratio, extrusion speed, and cooling distance. The optimal process parameters for fabricating PLA filament with a diameter of 1.7 mm include the barrel temperature of 184 °C, extrusion speed of 490 mm/min, cooling distance of 57.5 mm, and recycled material addition ratio of 40%.

“…Revuru et al [ 24 ] performed comparative studies on the performance of dry, flooded, and MQL machining with soybean vegetable oil-based cutting fluid using TiC/TiCN/TiN-coated carbide inserts in turning of 4140 steel. The authors found that feed rate is the most significant cutting parameters to influence the surface roughness while the cutting speed did not have any significant impact on the tool wear.…”

This paper reviews recent progress and applications of usage of cutting fluids in conventional machining processes. In addition to reviewing the various conventional and advanced cooling techniques during machining, the paper also discusses the use of minimum quantity lubrication (MQL) in several types on metals such as steel, aluminum, alloy, and titanium alloys. Due to the toxicity of conventional cutting fluid resulting in ecological problems, the demand for environmentally friendly cutting fluid is rising. Therefore, natural vegetable oil is chosen as potential replacement as an environmentally friendly cutting fluid which fulfills the important aspects of biodegradability and sustainability. Application of vegetable oil-based cutting fluids under MQL techniques are also discussed. Moreover, the potential of palm oil as biodegradable and environmentally friendly natural vegetable oil-based metal-working fluids in MQL are reviewed.

“…Recently, interest has been shifted towards using biodegradable vegetable oils in machining due to its higher viscosity index, higher flash point, fewer health risks, lower toxicity, lower disposal cost. Revuru et al [24] reported that as compared to dry and flood circumstances, vegetable-based soybean oil in MQL performs better in terms of machining characteristics. Pereira et al [25] evaluated the tool life of an end mill cutter while milling 718 under MQL conditions using various vegetable oils.…”

Environmental machining was investigated using coconut oil and minimal quantity lubrication (MQL) in the turning of AISI 316 stainless steel. The turning parameters and MQL flow rate were optimized using ANOM and ANOVA in multi-response analysis to obtain the best hardness and minimum surface roughness. The feed, speed, depth of cut, and MQL flow rate were used as input parameters. It was observed that minimum surface roughness (R a : 1.12 μm and R z : 6.37 μm) at cutting speed of 120 m/min, feed rate between 0.25 and 0.3 mm/rev, the depth of cut between 1.0 and 1.5 mm and a flow rate of 90 ml/h. The high hardness of 230 μHv at machined surface and machining affected zone (MAZ) was observed to a depth of 1.075 mm. The coconut oil was shown to be an ecofriendly lubricant for machining difficult-to-cut materials like stainless steel and keeping good surface integrity.
