Abstract

Hasil produksi cetak tiga dimensi tipe FDM (Fused Deposition Modeling) dengan menggunakan material PLA (Polylactid Acid) yang tergolong material polymer pada umumnya mempunyai permukaan yang kasar sehingga memerlukan pekerjaan akhir untuk membuat permukaanya lebih halus lagi. Tujuan percobaan ini ialah untuk mengetahui ukuran Grit Size mana saja yang bisa menghasilkan nilai kekasaran permukaan yang paling rendah atau dengan kata lain mempunyai nilai kehalusan permukaan yang paling tinggi. Salah satu caranya ialah dengan menggunakan kertas gosok dengan variasi tingkat Grit Size yang biasa ditampilkan pada kode angka pada label kertas gosok. Pada percobaan kali ini, kami menggunakan Grit Size dengan ukuran 1000CW, 1200CW dan 1500CW. Parameter uji pada mesin cetak tiga dimensi dengan merek Leapfrog Creatr HS ini menggunakan PLA berdiameter 1.75mm, dengan temperatur Nozzle dan Base Plate sebesar 230oC dan 30oC, serta mempunyai feedrate dan infill density masing-masing sebesar 70%. Setelah dilakukan percobaan sebanyak tiga kali pengambilan data, kami dapatkan hasil yang dimana dengan menggunakan sand paper dengan grit size 1500CW mempunyai nilai kekasaran permukaan (Ra) yang paling rendah, yaitu sebesar 4,392 μm (N8).

Abstract

This paper presents the design and prototype of a Mini Automated Guided Vehicle (AGV) using a microcontroller. The mini AGV system is based on an autonomous forklift. The purpose of the AGV prototype is to move objects from one place to another and continuously. To run, AGV uses the Line Follower method by using four obstacle detection sensors or infrared transmitters and receivers. Furthermore, when all sensors are active, AGV will stop when there are objects with RFID tags outside. The RFID reader which is placed in front of the AGV activates a stepper motor which will move the object's fork. Then AGV sends the object to a predetermined place. Most components use compatible Arduino modules, except for the chassis and some parts use components made of acrylic or printed in 3D.

Abstract

Makalah ini memaparkan perancangan konveyor sabuk untuk mengangkut pasir besi sebagai material utama sandblasting di ruang sandblasting. Konveyor sabuk dirancang untuk menggantikan konveyor ulir eksisting yang sering berhenti beroperasi karena perbaikan bantalan yang rusak akibat penyisipan pasir besi ke dalam bearing. Selain itu, kapasitas angkut konveyor ulir dinilai tidak efisien karena sebagian pasir besi tidak terangkut karena tertinggal di celah antara screw dan pelat penutup. Berdasarkan pemeriksaan terhadap permasalahan yang ada maka disarankan dilakukan penggantian dengan konveyor sabuk dan dilakukan perhitungan untuk menentukan spesifikasinya sesuai dengan data konveyor yang sekarang dipakai. Hasilnya, konveyor sabuk dapat dirancang dengan kapasitas 236.81 ton per jam dan akan memiliki lebih sedikit kerusakan karena tidak akan ada kerusakan bearing seperti yang terjadi pada konveyor ulir..

Abstract

The method of producing items through synchronously depositing material level by level, based on 3D digital models, is named Additive Manufacturing (AM) or 3D-printing. Amongs many AM methods, the Fused Deposition Modeling (FDM) technique along with PLA (Polylactic acid) material is commonly used in additive manufacturing. Until now, the mechanical properties of the AM components could not be calculated or estimated until they've been assembled and checked. In this work, a novel approach is suggested as to how the extrusion process affects the mechanical properties of the printed component to obtain how the parts can be manufactured or printed to achieve improved mechanical properties. This methodology is based on an experimental procedure in which the combination of parameters to achieve an optimal from a manufacturing experiment and its value can be determined, the results obtained show the effect of the extrusion process affects the mechanical properties.

Abstract

The die design process for casting requires repeated testing in order to get a good die and produce a product that is as planned, which takes a long time and costs a lot for die making in this trial. The purpose of this study is to determine a more efficient process in die design by conducting a casting analysis using a MagmaSoft simulation. The sample part used in this study is a motorcycle brake master cylinder which will be made by the Gravity Casting process with aluminum material. The basic method used is die design using CAD by calculating Shrinkage allowance, and casting simulation using MagmaSoft software to find out various possible defects during the casting process, such as filling, air trap, solidification, hot spots, and shrinkage porosity. The simulation results show that in the filling process there is no indication of cold shot and no air trap problem, solidification and hot spots are good and occur in the part area, and there is little porosity. In general, the simulation results show that the die design has met the requirements, although there is porosity, this porosity occurs in the area that will be lost after the machining process

Abstract

Additive manufacturing (AM) or commonly called 3D printing (3DP) and rapid prototyping (RP) is a  technique of blending materials by either fusion, binding, or solidifying materials. Despite many advantages of AM, there is a drawback  of AM such as the surface quality may not be as good as subtractive machining  (SM) process, therefore it will be better to have the initial shape forming process with AM and then finishing the required surface with SM process within a single setup. This paper presents the preliminary design of hybrid AM-SM machine to process a resin based material. The design includes structural design and control design of the machine using the material and firmware widely available in the market. Keyword: Additive, Subtractive,  Manufacturing,  Hybrid  Machine

Abstract

One of very important and vital tool in road marking is road mark erasing machines. In general, the machine used to repair road markings is a road marking erasing machine that is pushed manually. However, this machine has a disadvantage that requires a long time in the process of erasing the road marking, so making it less efficient. Therefore, the truck road mark erasing machine is one of the options to replace the erasing machine that is pushed manually. The machine uses a grinding system with a vertical blade eraser position and hydraulic power to drive the blades as it is able to withstand shock loads and thrust upwards due to the removal process, having overload protection, and the size of components are not large. The study started with doing observation to the existing manual erasing machine, then determining the required blades and calculating as well as selecting the required components of the hydraulic system.  Based on the calculation, the blade specification was obtained and selected, i.e surface milling cutter of type WFX12200R from Sumitomo Electric Hardmetal Corporation having rotation speed 750 rpm, hydraulic motor from Danfoss of type OMR-80 having torque 136 Nm dan displacement 80.3 cc/rev., and using hydraulic pump from Parker of type 0210 having displacement 21 cc/rev. From the test result in the field, this machine is three times faster than the manually pushed machine, less number of the blade used, and the engine as a resource on the machine is more durable.

Abstract

Universal Testing Machine or UTM (Universal Testing Machine) is a material testing machine that has more than one type of material testing. The purpose of this research is to design and analyze the strength of the UTM construction for tensile and bending tests. This machine uses a hydraulic jack as a power source to provide the required load. The design is limited to a load of 1.4 tons while the maximum construction load is 5 tons according to the hydraulic jack capacity. The method used in this study begins with a design using CAD and then analyzed with the finite element method. From the results of the analysis and evaluation, the designed tool can be used safely in accordance with the specifications used. The results showed that from the experimental results on the tensile and bending test specimens, both tests were successfully carried out. The tensile test was carried out with SUS 304 and SS400 with different thicknesses with dimensions according to ASTM E8 standards, while the bending test was carried out on ASTM A36 material with a size of 200 x 40 x 6 mm. After the test is carried out, the construction of the machine is checked for possible defects due to the test, namely the upper and lower clamps, punches and dies, and the engine frame. As a conclusion, after testing, it turns out that no damage or defects were found in all the parts examined
