Abstract

In the machining process, one of the things that cannot be released is the occurrence of burr formation or chip that sticks to the moment after the deduction process is carried out. To reduce burr formation is usually by determining good cutting parameters and given a cooling medium that functions to control the temperature during lubrication.This study aims to determine the burr formation on the 1100 aluminum sheet material using the machining method of milling raouter with the depth of feeding in accordance with the thickness of the workpiece. The spindle rotation used is 1200 rpm with a variation of the cutting tool eyes that is 4 mm, 6 mm, and 8 mm of the HSS tool brand and variations of the cooler namely air, coolant, oil. This research uses taguchi and ANOVA methods by measuring burr formation using USB microscope with 1200 x magnification. Then get the smallest burr formation value of 0.16819 mm with the parameter arrangement of the diameter of the drill bit 6, (f) 40 mm / minute, oil coolant. As for the Exit (outlet) the smallest burr formation of 0.27211 mm in the arrangement of the diameter of the tool diameter of the 4, (f) 50 mm / minute oil cooler.

Abstract

This research was conducted to determine the effect of variations in activated charcoal media and temperature variations on the price of rockwell hardness and the chemical composition of ST 37 steel in the carburizing process. The carburizing process is widely used to increase hardness and add carbon to steel which has a low hardness value and needs to be given special treatment to increase the hardness of the steel. In this study, the carburizing media used were mangrove charcoal, coconut shell charcoal, lebanese wood charcoal that had been made into powder and a mixture of BaCO3 as a catalyst. In this study, the carburizing process was carried out with temperature variations, namely 750oC, 850oC and 900oC after reaching the desired temperature and then held with a holding time of 2 hours. The percentage of carbon absorption is more absorbed in lebanese charcoal at a temperature of 900oC with the addition of carbon by 0.61%. Whereas for rockwell hardness testing the highest hardness value at 900oC was found in lebanese charcoal with a hardness value of 79.9 HRC.

Abstract

Serbuk kayu merupakan limbah yang dihasilkan dari proses pemotongan atau pengamplasan kayu dengan cara digergaji atau menggunakan permesinan seperti drilling, milling, sander, grinding, dan lain-lain pada suatu industri. Limbah serbuk kayu pada suatu industri biasanya dibiarkan menumpuk, dibuang, atau dibakar. Hal ini terjadi karena kurangnya informasi tentang dampak negatif limbah serbuk kayu dan daur ulang limbah serbuk kayu. Untuk membuat papan kayu dari limbah serbuk kayu dibutuhkan mesin press hidrolik serbuk kayu. Mesin press hidrolik serbuk kayu didesain dan ditargetkan untuk masyarakat skala kecil atau menengah kebawah dan UKM yang mengolah limbah serbuk kayu. Sistem pada mesin press serbuk kayu dibuat manual dan dimensi pada dies atau cetakan dibuat sesuai dengan kebutuhan pasar sehingga tentunya akan menguntungkan pihak pengrajin kayu atau UKM yang mengolah limbah serbuk kayu. Dimensi alat sangat penting dalam produksi limbah serbuk kayu.  Pentingnya  dilakukan  pengukuran  dimensi alat dan  massa dari alat bertujuan apabila ada usaha untuk memproduksi alat dalam jumlah besar dan  kemudian  menjualnya.

Abstract

This study analyzes the effect of Shielded Metal Arc Welding (SMAW) welding process parameter variations on the quality of welded joints in 304 stainless steel by varying the current (65 A, 75 A, and 95 A), electrode diameter (2.0 mm; 2.6 mm; 3.2 mm), and weld type (I, V, and X). Evaluation is carried out through tensile tests to determine tensile load, stress, and strain, as well as Non-Destructive Test (NDT) dye penetrant method to detect surface defects. Taguchi L27 design is used to analyze the contribution of each parameter to the quality of the joint. The results show that current is the most influential factor on tensile strength, followed by electrode diameter and weld type. The optimal combination is obtained at a current of 95 A, a 3.2 mm electrode, and an X (double V) weld, with an average tensile load of 87.65 kN, a stress of 730.42 MPa, and a strain reaching 100% which shows the best mechanical performance. Overall, this study confirms that proper welding parameter settings are crucial for the mechanical integrity and quality of 304 stainless steel welded joints.
