Abstract

This paper discusses the process of restoring the original condition (recondition) of DoAll LT 13 Bu01 by focusing on electrical system improvements, geometric precision and machine performance. Direct observation methods are applied to solve problems that include cause and effect relationships using 5 (five) why analyzes. The reconditioning stage starts from the initial data collection of damage obtained by visual inspection, function testing and geometric testing on the machine; then proceed with analyzing the damage; and corrective actions based on the results of the analysis. Functional testing methods, geometric deviation tests, machine performance tests are performed to see the achievement of recondition goals. Based on the results of the tests performed, the function of the electrical system returned to normal, the average value of geometric deviation still satisfied based on ISO-1708 standard and machine performance for spindle rotation value with 5% deviation, the value of the roundness and taper work-piece results of 0 and 0.004mm / 255mm, respectively and spindle vibration in the range of 0.33 - 0.66 mm / s RMS for speed 50 - 2500 RPM is still considered normal based on ISO 10816 standards.

Abstract

Vibration measurement technology using conventional sensors such as piezoelectric (PZT) Accelerometer is still expensive. Currently, many low-cost vibration measuring devices have been developed by using Micro Electro Mechanical System (MEMS) technology. This study aims to analyze the results of vibration measurement system MEMS Accelerometer ADXL345 with PZT Accelerometer. This research applies design and develop approach with comparative data analysis technique, that is comparing data of result of measurement of MEMS Accelerometer ADXL345 to PZT Accelerometer Vibroport80. The construction comprises the ADXL345 sensor connected to the Arduino Mega 2560 microcontroller operated by Widows operating system and programming language Arduino IDE 1.08. Testing of measurements at Bearing speeds of 500, 1000, and 1500 RPM with length of time measurements at 5, 10, and 20 seconds respectively. The analysis of the test results shows that the MEMS Accelerometer ADXL345 of vibration measurement system can measure, process and display vibration measurement data larger 3% than PZT Accelerometer and can provide the best measurement accuracy at 20 seconds measurement length of time.

Abstract

Lathe is a tool that rotates the work-piece about an axis of rotation to perform various operations such as cutting, sanding, knurling, drilling, or deformation, facing, turning, with tools that are applied to the work-piece to create an object with symmetry about that axis. There are several considerations that affect the lathe to work well, especially geometrical deviations that affect the quality degradation of the product in terms of shape and dimensions. One of the wear on the slide-way of the lathe can affect geometric aberrations. This paper discusses the design and manufacture of grinding tools to fix the lathes bed that can erode three slide-way planes in a single process to achieve flatness and square alignment with one another. The research method used is the experimental method by collecting the data needed to design the tool through literature study and direct observation to the lathe, then the data is processed to obtain the specification of the tool that will be designed by design method based on Verien Deutche Ingenieuer (VDI) 222 , the design result is then continued with the machining and fabrication process; before assembling, parts of the auxiliary equipment are tested in accordance with the design function indicator; the last stage is testing the tool as a whole to know the achievement of the tool against a predetermined goal. Based on the results of the grinding experiment on the three slideway planes with a feed depth of 0.03mm, the average flatness and alignment values ??are 0.02mm / 300mm and 0.07mm / 300mm, respectively. Based on the ISO 1708 standard on the tolerance of geometrical deviations, the grinding results have not allowed the tolerance. Still need more research about the influence of wear of grinding wheels to the grinding results.

Abstract

The recondition of the Aciera f3/07 milling machine has been done to restore the machine condition to be ready for use. The machine was damaged and caused the machine to be unable to operate and made electrical and mechanical components fail. The feasibility of the machine is tested to see the achievement of the purpose of machine reconditioning. This paper aims to see the results of the geometric testing of the machine compared with the results of running test and the vibration measurement of the machine parts. This study uses an experimental method, where damage to the machine will be identified and the damage will be immediately carried out repairs or replacement of spare parts. Furthermore, machine performance was testing including machine geometry testing, vibration testing and running test in accordance with ISO-1708 standards. The test results show that there is no significant differencebetween the results of the geometric precision testing of the machine on vibration testing and road testing. This can indicate that all three tests can be used as a reference in validating the results of machine repair, especially repairing irregularities in the geometric accuracy of the Aciera F3 milling machine.

Abstract

The service of Pelabuhan Perikanan Nusantara Sungailiat workshop to fishermen was disrupted due to reduced machine availability caused by the failure of lathes, hydraulic press,  drills, and grinders. This project aims to repair machine damage, so machine availability increases and workshop services return to normal.. The implementation method is carried out with corrective maintenance procedures to identify and fix the cause of damage or failure in a failed or damaged system. To verify the types of problems affecting machine’s condition using the Six Sigma DMAIC (Define-Measure-Analyze-Improve) methodology and why-why analysis. The results indicate that lathes, hydraulic presses, drills, and grinders can function well. Even though the hydraulic press machine can perform to press the product, it has not returned to the factory standard. Overall the machines can be used to provide repair services for fisherman boat engine tools/components and fishing gear. It is necessary to build a preventive maintenance system and the performance parameters of these machines so that their condition is always maintained and damage does not recur.

Abstract

Friction welding is a welding technique that melts metal. Jointing of metals by utilizing the heat generated by friction between metal surfaces in which variations in the pressure distance are determined. The purpose of this study is to determine the strength of the welded joint after the welding process by using variations in the pressure distance of 3mm, 4mm, and 5mm. The material used in this research is carbon steel S45C shaft. Studies have shown that welding at the deepest compression distance produces a very strong welded joint, the greater the stress during the welding process, the stronger the joint in the welding. Welding with compression distances of 4mm and 5mm. and the impact price is higher compared to the 3mm pressing distance.
