Abstract

Teknologi 3D printing berkembang pesat dan menjadi solusi inovatif dalam berbagai industry yang diawali dari pembuatan prototipe sehingga produksi massal. Material ABS (Acrylonitrile Butadiene Styrene) dan PLA (Polylactic Acid) digunakan karena memiliki karakteristik fisik yang kuat dan simplification of the printing process. Namun, tantangan utama dalam 3D printing adalah akurasi dimensi hasil cetakan, yang dapat dipengaruhi oleh parameter proses seperti infill density dan wall loops. Kedua parameter ini memberi pengaruh bagaimana material disusun selama proses pencetakan, yang berdampak langsung pada dimensi akhir produk. Ketidakakuratan ini dapat menyebabkan kerugian materi, waktu, dan biaya, serta mempengaruhi kualitas produk akhir. Tujuan penelitian ini untuk mengevaluasi pengaruh parameter proses tersebut terhadap akurasi dimensi hasil cetakan, guna mengidentifikasi kombinasi optimal yang menghasilkan cetakan terbaik. Metode yang dilakukan secara eksperimental menggunakan 3D printing, bahan fillamen PETG (Polyethylene Terephthalate Glycol) dengan melakukan variasi parameter proses dan pengukuran akurasi dimensi hasil cetakan. hHasil cetakan berupa prototype funnel air velocity karburator sepeda motor. Hasil penelitian menunjukkan bahwa infill density relative kecil memberi pengaruh terhadap perubahan pada dimensi luar, namun pada dimensi ketebalan cenderung meningkat dengan peningkatan jumlah densitas. wall loops memberi pengaruh kestabilan dimensi dan mendekari dengan dimensi referensi diameter funnel air velocity pada 6 wall loops sebesar 72,09 mm.

Abstract

One of the fastest-growing industries in this modern era is automation, with the goal of enhancing efficiency, productivity, and precision. In this context, production system automation is key to achieving these goals. This research reviews the use of pneumatic linear transfer systems in modern manufacturing industries that are oriented toward efficiency, productivity, and flexibility. This research uses the VDI 2221 method in conjunction with structured design approaches and pneumatic technology to design and construct a multi-speed pneumatic linear transfer system. New developments in the pick-and-place system allow it to accelerate for picking up objects and decelerate for placing them utilizing a pneumatic system. With an emphasis on enhancing production process efficiency, productivity, and flexibility, it is hoped that this research will significantly contribute to developing automation technology in the manufacturing sector. The FEA analysis results also show that this multi-speed pneumatic linear transfer system tool can safely accommodate the applied load.

Abstract

In the industrial era 4.0, the automation system technology used is growing rapidly. Automation systems in the industry are very useful, especially in reducing production time. One of the tools that can be used to simulate production in an industry is the Modular Production System (MPS). MPS itself consists of several stations to simulate the production process on a small scale. In a production system, of course, a system is needed that can detect abnormal workpiece conditions. This system will be driven by a Programmable Logic Controller (PLC). This system will be placed at the distribution station. The rejection system in MPS is needed because, in MPS there is still a manual process, namely in the process of inserting workpieces into the stack magazine. with this manual process, it is likely that workpieces with abnormal conditions will be processed by MPS. This condition is unlikely to be processed further to the pick and place station. Therefore, objects with abnormal conditions must be separated by this rejection system. There are 2 methods used to conduct this research, namely using the 5/3 valve and the positive stop method. Data collection from both methods is done by experiment. From the experimental results of the two methods, it can be seen that the best method used for this system is the positive stop method. This method is the most appropriate method because it can produce a very accurate swivel arm stop position. From the data obtained, using the 5/3 valve method with a pressure of 4 bar the swivel arm stop position ranges from 22.4 cm to reach more than 25.8 cm, and at a pressure of 5 bar the swivel arm height ranges from 25.8 cm to more. By using the positive stop method the swivel arm stops exactly at the specified swivel arm height because the swivel arm is held by the pneumatic cylinder.

Abstract

A robot arm is a robot component in the motion subsystem of a robot system to determine the position and orient the object so that the robot can perform certain tasks, such as picking and placing an object. To use it as a pick and place, a gripper shaped like a human finger, commonly called a jaw gripper, is required, which is used to hold, tighten, hold, and release an object. The shape of the jaw gripper is designed and made according to the shape of the workpiece to be grasped, which was created by PT Matahari Megah using the 3D-printing method for its customer. The jaw gripper that has been designed still needs to be developed to produce a more optimal jaw gripper design, such as by reducing the use of excessive filament without reducing quality and minimizing costs incurred. Therefore, a more optimized jaw gripper test tool was made with a material reduction method using the generative design process in Inventor software, and physical testing was carried out on the ability to grip and deflection, compared to the testing process using a test system that had been designed with a dial gauge measuring instrument. The results of the comparison between the Inventor software results and the simulation results do not exceed 10%, with the difference at a pressure of 2 bars of 7% and the difference at a pressure of 4.6/5 bars of 1.87%.

Abstract

Nowadays, the application of automation in the manufacturing sector is important to increase production efficiency. One of the variations in industrial automation is the vacuum gripper. Vacuum grippers are specifically designed to handle specific workpieces, such as labeling application. Label characteristics that easily bend and stick to the workpiece when peeled off require a specific gripper. This research was carried out using 2 methods, experimental method and CFD simulation method. The experimental method was carried out by collecting pressure data with Arduino. Data from this experiment will be used for the CFD simulation. Based on these experimental tests, the average vacuum pressure obtained was -44.372 kPa. From the simulation vacuum pressure on the 12 inlet holes was obtained. The largest vacuum pressure was at inlet 12 with a vacuum pressure value of -44372.11 Pa, while the smallest was at inlet hole 1 with a value of -44371.86 Pa. The pressure distribution is evenly distributed at all the suction point and has suited the design requirements.

Abstract

Modular Production System is a station unit consisting of industrial components in the form of pneumatic and electrical components controlled by a Programmable Logic Controller which is directed for industry-oriented vocational training. In a Modular Production System, there are several types of stations, one of which is the pick and place station which consists of two modules, namely the pick and place module and the conveyor module. This design discusses the optimization of the design of the top cover feeding unit at the pick and place station because the top cover is dislocated every time there is a change in position when the vacuum sucks the top cover. This design optimization is done by redesigning the feeding unit slider. By doing this optimization, it can make the feeding unit accommodate the top cover where it should be and improve the process capability of the system. The results of this optimization are determined based on the process capability values, before optimization the resulting values were 1.0417 for Capabiity Process and 0.77 for the index. Then after design optimization, the values are 3.402 for Capabilty Process and 6.396 for the index and produce a total force of 0.205 N by using a slider feeding unit tilt angle of 14o. This tilt angle was determined as the most optimal angle because it resulted in the least system failure.
