Abstract

The persistent challenges in material forming processes arise from recurrent issues encountered during the deep drawing process, particularly involving cracks and deviations from standard thickness dimensions. This article investigates the deep drawing process using both experimental and numerical methodologies. The experimental approach employs a 40-ton capacity power press machine, while the numerical method utilizes the ABAQUS student version software. SPCC-SD (JIS G3141) is the selected material for producing a Dop-pipe 2-inch diameter pipe cap in both approaches. Noteworthy findings include the highest positive and negative correlations observed in elements E 46 and E 48, with values of 0.715 and -0.933, respectively. Minimal disparities, averaging around 4.6% for all components, were evident between the experimental and numerical methodologies. The numerical approach yielded predictive results identifying potential issues in elements E 47 and E 48. This observation did not reveal instances of tearing failure but instead showcased an increase in thickness due to a higher axial force between the dies and punched-in components. The study successfully and accurately predicted product thickness for all components, presenting a contrast with outcomes obtained through the experimental method. Furthermore, this research advances the deep drawing process, extending its applicability to broader material forming applications and ultimately enhancing overall production process efficiency.

Abstract

Industrial developments, especially in the manufacturing and construction sectors, recognize L-hanger ducting as a critical component in HVAC (heating ventilation and air conditioning) ducting systems, which play a role in supporting and stabilizing air ducts. The L-Hanger ducting manufacturing process involves a series of stages, such as shearing, blanking, piercing, trimming, and bending processes. This research focuses on the design and simulation of dies and punches for piercing, blanking, and bending processes using 1.6 mm-thick SPCC-SD material. The aim of this research is to design and analyze progressive dies in order to increase the efficiency of the production process. A comprehensive calculation of the forces involved in the shearing, blanking, piercing, trimming, and bending processes is required in order to predict press machine tonnage requirements to support the production process. This research applies theoretical and numerical validation approaches. Theoretical analysis is used to calculate the overall forces, which are then compared with numerical results and verified through an experimental approach. By understanding and optimizing the design of progressive dies, it is hoped that we can increase the production efficiency of L-hanger Ducting and expand knowledge in the field of metal forming, contributing to the metal forming industry and supporting the development of science.

Abstract

The results of an experiment that used an orthogonal Taguchi method to improve shielded metal arc welding (SMAW) were given. The SMAW method was used to join dissimilar metal of SPHC and St. 30. SPHC material has a low carbon steel content, while St. 30C steels contain a medium amount of carbon steel, which is used for tractor shaft axles. Carbon percentages vary slightly between the two substances. This study aimed to achieve the highest possible quality of tensile strength by utilizing the specified SMAW parameters. SPHC material has a low carbon content, whereas St. 30 steel has a moderate carbon content. This study used the Taguchi experimental method with three input variables and three experimental levels. The SNR ratio is used to evaluate the most optimal SMAW performance. ANOVA analysis is used to evaluate the most crucial parameters in determining the response variable. This research has successfully provided input on the combination of SPHC and St. 30C for SMEs. It operates effectively with a welding current of 133 A, a welding voltage of 9 V, and a filler diameter of 2.0 mm. The S/N ratio analysis found that the welding current, voltage, and filler diameter all had a significant impact on the outcome.

Abstract

The use of press machines in stamping is an important aspect of the manufacturing industry, especially in producing efficient and quality components. This article aims to analyze the cost of the stamping process using mild steel SPCC-SD material measuring 200 mm x 25 mm x 0.8 mm, using two types of press machines, namely 80 tons and 40 tons. Through the cost analysis method, the total cost of the stamping process for the 80-ton press machine is Rp 16,417.4 per 10 pcs, while for the 40-ton press machine, it is Rp 15,028.5, indicating the cost efficiency of the 40-ton press machine is around 8.5%. The tonnage calculation shows that the 40-ton press machine is adequate for the blanking process, with a tonnage requirement of 4 tons, far below the available capacity. These results provide recommendations for the use of 40-ton press machines in the production of steel components on a small to medium scale, considering cost efficiency and optimal performance. This work is expected to increase productivity and cost efficiency in the manufacturing industry, especially at PT GA.

Abstract

This investigation focuses on optimizing the sinker electrical discharge machining (sinker-EDM) process parameters for high tensile strength steel (HTSS), specifically SKD-11, utilizing Box-Behnken Response Surface Methodology (BB-RSM). Sinker-EDM is a commonly used technique in manufacturing moulds, dies, and components for sectors like automotive and aerospace. This process eliminates direct contact between the electrode and the workpiece. However, its low material removal rate (MRR) constrains productivity. This research endeavours to enhance MRR by employing rectangular graphite electrodes. The Box-Behnken Response Surface Methodology (BB-RSM) was utilized to evaluate the effects of pulse current, spark-on time, and gap voltage on MRR. The optimal MRR of 45.49 mm³/min was attained at a pulse current of 16 A, spark-on time of 400 µs, and gap voltage of 45 V. ANOVA revealed that pulse current and spark-on time significantly influenced MRR. In contrast, gap voltage had an insignificant impact. Interaction and surface plot analyses confirmed that high pulse current and extended spark-on time resulted in the maximum MRR. These findings provide valuable insights for optimizing the sinker-EDM process for SHTSS, contributing to enhanced productivity and efficiency in manufacturing.

Abstract

The car body repair process is integral to vehicle development and structural repair. The primary objective of this study is to enhance the quality of thin material welding utilized in automobile body repair. The impetus for this research stems from the necessity to improve the structural integrity and longevity of thin materials prone to deformation throughout the welding procedure while minimizing distortion. This study aims to identify optimal parameters for the tungsten inert gas welding (TIG welding) process on thin materials, particularly for automobile body rearrangement. The Taguchi method conducted the experimental analysis of variations in welding parameters, including electrode diameter, gas flow rate, and welding current. Adjusting TIG welding parameters to their optimal values significantly improves weld joint direct tensile load (DT-load) and overall structural quality, according to the findings of this study. ANOVA analysis and the S-N ratio indicate that gas flow rate and welding current are significant determinants of the quality of welded joints in thin materials. This research contributes to a better understanding of the optimal parameters for fusing thin materials, particularly in automobile body repair. The automotive industry can use these findings as a guide to enhance the quality and strength of welding processes, which are critical to the structural integrity of vehicles.

Abstract

Laser marking has become an industrial trend to label a product to avoid problems arising from errors in product placement, labels can also be other markers depending on needs, laser marking can provide good writing prints on steel sheets. However, problems arise due to poor parameter input errors resulting in marking reading results that cannot be read by the scanner machine, this study aims to provide an analysis of the influence of laser marking input variations that can provide good marking quality, to determine the quality of marking, researchers use a Logitech camera assisted by Open CV programming, to see the quality of laser marking results that can be read by the scanner. This research method begins with inputting 6 parameter variations including speed, laser power and laser frequency, then Open CV programming is carried out to obtain image reading quality with color and line recognition, the reading results will automatically display the error level of the study. The results of the study explain the first test with a high error rate due to low input variables so that the reading is not clear, while the error value is 104040 in color recognition and 69024 in lines that are read with a 100% end range. The lowest error value is in the second test with the highest input variable, namely 1309 in black and white color recognition and 1345 in lines with a range of 100%, therefore the sixth test can be read clearly and well.
