Abstract

Makalah ini menyajikan studi pada mini excavator Excava50. Dari sekian banyak komponen pada sebuah excavator, komponen boom adalah komponen yang sangat vital karena mendukung seluruh beban kerja pada saat beroperasi. Studi ini dilakukan dengan menggunakan analisis elemen hingga pada komponen boom dengan memanfaatkan data dari komponen boom eksisting, baik dimensi, beban kerja, dan material yang digunakan. Selanjutnya umur kelelahan komponen boom juga dihitung untuk memperkirakan umur pakainya. Hasil simulasi dengan software CATIAV5 memperlihatkan bahwa komponen boom tersebut aman digunakan dengan perkiraan umur pakai mencapai 50 tahun.

Abstract

Nowaday, the use and demand of laser engraving machines is increasing for production and practical activities in vocational schools and engineeringfaculty in Indonesia. However, the price of laser engraving machine in the market is still quite high. Therefore there is a need to find a solution to overcome this problem by designing a laser engraving machine that is devoted for practical purposes at affordable prices. The control system on the laser engraving machine is designed using an Arduino Nano-based 2-axis CNC controller, with three stepper motor drive actuators, to drive the machine on the x, y, z axes and laser axis with 2500 mW of power. To prevent damage if there is a movement error, the machine is equiped with emergency stop button. The use of a control system with an Arduino nano-based 2-axis CNC microcontroller is selected on the Laser engraving machine because it is open source and more affordable. It is expected that by implementing Arduino nano ATmega328 microcontroller as a prototype, in the future the control system can be developed further so that the control system is more stable. From the results of laser engraving machine testing using laser distance parameters, laser power and laser speed motion, obtained the value of the best engraving machine parameters to be used as standard parameters.

Abstract

This study was conducted on stamping die design for one of the car body parts using the FTI Forming Suite software. In general, the design process of existing stamping dies in the observed companies involves seven to ten trials before obtaining an acceptable die, which consequently increases the cost of the die. By using the software, it is expected that the number of trials will be reduced because the design is analyzed first to identify unwanted defects in the stamping process, such as wrinkles, splits, and springbacks. The study begins by comparing the stamped parts with the design. Using a 3D scanner, the geometry of the parts is obtained and compared to a original 3D CAD model to check for deviations of the parts from the original design. Comparison between the stamped parts and the original design shows discrepancies. This is most likely because the design has been modified to prevent stamping defects. Furthermore, the original design is simulated by applying a blank holder force of 109.7 kN. The first simulation on the original design showed that the thickness strain was -14.4% and had a strong wrinkling tendency, therefore the modified design was then simulated again on this modified part design. Modifications mainly focused on the essential corner radius, as well as on the blank holder force to 129.2 kN to prevent wrinkling and reduce springback. The second simulation produces good formability as shown by the forming limit diagram (FLD), safety zone, and better springback, even though the minimum thickness strain increases to -19.2%. Thus, by using simulation software, the correct die geometry can be obtained prior to die making to avoid unnecessary die modification costs during the trial run. In addition, the number of trials can be minimized so that the lead time for stamping dies production is shortened.
