Abstract

It is normal to apply cutting fluid to machining, but using it excessively will harm the environment. One of the efforts to reduce it is to apply minimum quantity lubrication (MQL). This study aims to minimize the use of cutting fluid by designing a cutting fluid delivery system with Arduino Uno control. The developed MQL system can be controlled both based on temperature and time. This MQL system was a development from the previous system by replacing the limit and temperature sensor, nozzle, and mini compressor with a sprayer. The performance of this new MQL system was compared to a flooded cutting fluid feeding system. The experimental design of Taguchi L9 (3^4) with additional varied factors such as depth of cut, cutting speed, and feed rate. Each factor consisted of 3 levels. The measured output was cutting fluid consumption. S/N ratio analysis showed that the method of giving the cutting fluid most dominantly affected the outcome. ANOVA showed that more than 97.56% of the factors were dominated by the method. The combination of factors that would produce a minimum burst at a rate of 180 ml/hour if applying a combination of factors and a level of depth of cut 1.8 mm and a cutting speed of 120.89 m/min, provision of cutting fluid with the periodic MQL method and feed rate of 0.122 mm/rev. Meanwhile, the metal removal rate (MRR) analysis recommended the use of periodic cutting fluid methods at a depth of cut of 2.2 mm. The development of the new MQL either temperature control or periodic system control, both were able to comply with the MQL criterion, i.e. the maximum spray of 500 ml/h.

Abstract

3D printing is a process of making three-dimensional solid objects from a digital file process created by laying down successive layers of material until the object is created. Many filaments can be used in 3D printing, one of which is PETG (PolyEthylene Terephthalate Glycol). PETG is a modification of PET (PolyEthylene Terephthalate) with added glycol at a molecular level to offer different chemical properties that provide significant chemical resistance, durability, and excellent formability for manufacturing. This study aims to find the most optimal parameter of surface roughness of PETG with different parameters of nozzle temperature, infill geometry, layer height and fan speed. Taguchi L16 (44), with four levels for each parameter, was used to determine the effect of each parameter. Each experiment was repeated five times to minimize the occurrence of errors. Based on the result, the effect of each parameter is nozzle temperature at 4.9%, infill geometry at 5.9%, layer height at 82.3%, and fan speed at 4.6%. Layer height has the highest effect on surface roughness, and other parameters have a low effect, under 7%. Research shows that the optimal combination of parameters is a nozzle temperature of 220 °C, infill geometry zig-zag, layer height of 0.12 mm, and a fan speed of 80 %.

Abstract

Success in the injection molding process is seen from the results of products that do not produce defects. Warpage defects are one of the defects resulting from the injection molding process. One way to measure warpage defects is to use the ImageJ application. The data processing stage in this study uses the Taguchi method statistical method with two independent variables namely holding time and mold temperature, each of which has three factors and repeated data three times, which aims to obtain more accurate values. The results showed a very influential variable is the holding time parameter then the mold temperature parameter. The higher the level of holding time parameters, the smaller the result of warpage defects. Unlike the holding time parameters, the best mold temperature parameters at the middle level, the result will be a small warpage defect produced. The experimental results of the highest level value on the holding time parameter are 15 seconds while in the mold temperature the value of the middle level is 50 ° C which produces a defect of 1%. While the lowest holding time parameter value is 5 seconds and the highest mold temperature level parameter value of 70 ° C is the worst variation of parameters because it produces a defect of 22%.

Abstract

Metal matrix composites generally use Aluminum (Al) as its matrix because of its low density, high processing, and high ductility. Ductility is an important factor that must be possessed on the metal matrix composite because the amplifier used is rigid and brittle. Alumina (Al2O3) is used as a reinforcing particle in a metal matrix composite because it has good thermal stability and hardness as well as a high Young modulus. Aluminum-silicon alloys (Al-Si) are excellent alloys of good melting, which have a good surface, without brittleness, and are excellent for cast alloys. The addition of magnesium (Mg) resulted in a modified rate of silicone eutectic for Al-Si-Mg, with enhanced magnesium (Mg) levels, increased alloy tensile strength but a decreasing percent elongation value. Strontium (Sr) is a common element used to modify eutectic and Si-shaped phases of rough acicular into finer and rounded fibrous forms. A metal matrix composite with a nano-sized Al2O3 particle amplifier can be fabricated using stir casting method with the addition of Mg as a Al2O3 wetting agent. Test results of the addition of Mg, Sr, and nano-Al2O3 to the highest hardness of ADC12 / nano-Al2O3 composites were found in ADC12-8Mg-0.03Sr / 2.5nano-Al2O3 variation at 78.92 HRB.
