Abstract

Perkembangan industri manufaktur sangatlah cepat. Salah satunya di bidang pengecoran logam dan permesinan lanjutan yang menerima pesanan dalam bentuk mass production. Salah satu produk komponen yang diproduksi adalah Suction Casing. Produk ini merupakan komponen bagian dari Cenrifugal Pump, Suction Casing merupakan rumahan untuk pompa untuk melindungi komponen di dalam pompa agar aman saat digunakan. Terdapat dua proses permesinan dalam produksi produk Suction Casing ini dan kedua proses ini dikerjakan di mesin yang berbeda. Untuk proses pertama dikerjakan di mesin CNC turning dan untuk proses kedua dikerjakan di mesin CNC milling dan proses kedua inilah yang penulis teliti lebih lanjut. Dalam pengerjaan produk suction casing ini diperlukan clamping system agar benda kerja tidak bergerak disaat cutting tool sedang memproses benda kerja tersebut. Pekerjaan ini sebenarnya masih bisa lebih efisien yaitu dengan cara menggunakan Jig and Fixture agar pengerjaan bisa lebih dari satu produk per proses permesinan. Untuk jig fixture suction casing ini dapat menghasilkan dua produk dalam waktu kurang dari 12 menit dan jika ditotal dalam satu shift bisa mendapatkan 192 pcs produk suction casing.

Abstract

The rubber products industries of the automotive sector are rapidly growing in Indonesia. In the manufacturing process, rubber products are often produced with compression molding because it is cost-saving. Manufacturers of rubber products are facing an obstacle in shrinkage but often ignored because it is still in minor data. Based on this, research analysis of O-Ring shrinkage was carried out. The purpose of this research is to obtain low shrinkage results from the right combination of parameters and the influence of those parameters. The parameters in this research are the type of rubber compound, press time, and heating temperature, while the response variable is shrinkage dimensions of small, medium, and large sizes O-Ring products. The experimental design and analysis were determined based on Taguchi's method. The results oif the analysis for Small O-Ring responses showed the parameters of the optimum condition process were obtained using the TO compound, 10 minutes press time, and 165°C heating temperature. For medium O-Ring responses, the TO compound, 10 minutes press time, and 185°C heating temperature were used. For large O-Ring responses used PPS compound, 10 minutes press time, 185°C heating temperature. As for the contribution of eachparameters for small, medium and large O-Rings, respectively; the type of compound is 25.334%, - 4.5571%, 5.9050%, press time 13.615%, -8.067726%, 17.7376%, heating temperature -3.758%, 19.772%, 59700%.

Abstract

Nowadays 3D printing technology is often used as a production machine, but production efficiency and good mechanical properties are priorities in the production process. Tensile strength and production time (building time) are some of the response variables of mechanical properties and production efficiency. In this study, the 3D printing parameters like nozzle size, layer height, print speed, and infill pattern will be used as an independent variables to obtain optimal output for tensile strength response and building time. The experimental design was calculated using the Taguchi method with an orthogonal matrix ( ) with 3 replications. Then the data was analyzed using Gray Relational Analysis to obtain the optimal combination of parameters for the combined response. After the prediction experiment had been conducted, a confirmation experiment was used as a validation of the experiment success. The optimal parameters obtained are nozzle size 0.8 mm, layer height 0.2 mm, print speed 50 mm/s, and concentric infill pattern with an average tensile strength of ±25.033 Mpa with a building time of ±28.0056 minutes. After analysis, the nozzle size parameter has a contribution of 44.39%, layer height of 42.31%, print speed of 1.18%, and infill pattern of 12.13% to the combinedresponse.

Abstract

Abstract – Failure on the bearing will cause a reduction in system accuracy, increased amplitudevibration or even failure on engine performance and produce unexpected consequences.In carryingout the analysis, the research method used in this study is an experimental quantitative researchmethod that is by simulating a spherical roller bearing model in ANSYS software to carry out stressdistribution analysis, deformation distribution and gravity load simulation that occur using staticstructural and Transient Simulation .From the results of static analysis using Static structural resultsin Annealed state, the maximum stress value is 4.8475 MPa, the total deformation value is 0.0001864mm and the force reaction value is 878.599 N. While the static calculation results of calculating inAnnealed state, the maximum value is obtained. stress is 5,343 MPa, total deformation value is0,000112 mm and force reaction value is 878,599 N and the results of dynamic analysis usingTransient dynamic in Annealed state obtained maximum stress value of 8,1951 MPa, totaldeformation value of 14,688 mm and force reaction value 6.31 x 10-7 N.
