Abstract

Titanium is a material that has a good strength to weight ratio, excellent corrosion resistance, and resistant to high or low temperatures Titanium alloys that are used in various industrial fields, one of them is the Ti6Al4V alloy. Micro drilling has a high rotational speed which results in tool wear, high temperatures, and surface roughness. This research uses The Finite Element Method (FEM) simulation. The application used is DEFORM 3D based on parameters from previous studies. The purpose of this research is to identify the progress of tool wear in a simulated manner on the Ti6Al4V alloy micro-dilling and analyze the tool wear on the Ti6Al4V alloy micro-drilling under dry machining conditions. Machining trials used CNC micro-drilling at various of cutting parameters such as cutting speed of 10.000 and 15.000 rpm. The results showed that the tool wear progress at the 5th hole was 0.00346 mm, the tool wear progress at the 10th hole was 0.00462 mm and the tool wear progress at the 15th hole was 0.00525 mm. Analyzing tool wear in simulated machining and experimental machining in dry conditions has a high wear value. Tool wear is simulated by measuring the radius of the tool in the 15th hole valued at 0.09973 mm. Tool wear is experimentally measured from the tool radius in the 15th hole valued at 0.0101 mm. The tool mesh is changed due to the tool wear. The tool mesh in the 5th hole is worth 17372 mesh. The tool mesh in the 10th hole is 15662 mesh. The tool mesh in the 15th hole was highly reduced by 13021 mesh. Tool wear affects the change in tool mesh. With increasing tool wear then tool mesh is reduced. The next cause of tool wear is the tool temperature in the machining process.

Abstract

Belt conveyor is a means of transportation used at Indarung IV PT. Semen Padang. Belt conveyor functions to move material from one place to another both in short distances and long distances with a certain slope. The capacity of limestone conveyor belt owned by Indarung IV is 400 tons/hour. However, this capacity is no longer able to meet the needs of limestone as a raw material for making cement in Indarung IV which currently reaches a capacity of 600 tons/hour. For this reason, an analysis of the 400 ton/hour capacity conveyor belt is still capable of transporting the limestone material with a capacity of 600 tons/hour, using the CEMA (Conveyor Equipment Manufacturer Association) standard. From the calculation results obtained belt conveyor parameters for a capacity of 600 tons/hour such as maximum belt capacity, belt speed, as well as the motor power and gearbox power needed for a capacity of 600 tons/hour. Where, some of these parameters exceed the value of the parameters of the conveyor belt capacity of 400 tons/hour, so the 400 tons/hour conveyor belt is unable to carry a load of 600 tons/hour. Replacement of some components is needed so that a load of 600 tons/hour can be transported.

Abstract

Cassava is a multipurpose plant. Apart from being used as a daily snack, cassava is also used as raw material for various industries. Currently, cassava processing technology has varied. One of them is a grating machine. The grating machine is used in order to make cassava into cassava pulp. In this research, the design of a cassava grater machine will be carried out. The design that is carried out focuses on the pulling system in the grated process. The design method used is VDI 2221. The stages in VDI 2221 are clarification of the task, conceptual design, embodiment concept, detailed design. Based on the results of the design carried out, several conclusions can be drawn, namely the chosen concept uses three towing rollers, a gear and a sprocket as a transmission roller pulling motion, while the gap control system uses bolts as the regulator. In addition, after carrying out the loading analysis on the shaft to be used as a towing roll, a roller with a size of Ø20mm can be used because the loading simulation results show that the maximum torsional stress value that occurs is 4.601 N / mm2 which is still much smaller than the value of the permitted torsional stress.

Abstract

Abstract In the SMAW welding process, the problem of welding defects is still often found. This can be the result of using an improper welding ampere. In this study, welding testing was carried out by utilizing variations in the use of a welding amper according to the electrode diameter. The welding process uses low carbon steel St 37 with 2F welding joints. The electrode used was AWS A5.1 E6013 with a diameter of 3.2 mm with a variation of amperage 85, 95 and 115. From the experimental results, it was found that for Amperes 85, it was found that the porosity welding defect and the welding leg showed poor results with a thickness of 5.7 mm and at Amperes 115 welding results show uneven welds and weld feet show good results compared to amperage 85 and 95 with a thickness of 6.1 mm. Observation of the welding arc at times (seconds) 10, 13, 15 and 17 for the amperage used, namely 85, 95 and 115, is obtained, the amperage of 85 shows the phenomenon of the welding arc movement is not normal at 10 and 13 seconds, at that second the arc length height is more than normal, which is 5 mm and 4.9 mm, the resulting defect is porosity. At 15 and 17 seconds, there is no defect in the welds. Amper 95 and 115 show the phenomenon of normal welding arc movement at 10, 13, 15 and 17 seconds and no defects occur. Observation of the results of welds on the weld toe found that, in the three amperage variations, there was a phenomenon that was not asymmetrical as the weld toe. The welding feet are not as symmetrical as the welding speed is different at layers 2 and 3.
