Abstract

Telah dilakukan pengembangan teknologi proses pembuatan komponen track link tank (rantai tank) scorpion untuk menanggulangi cacat cor. Track link tank adalah bagian komponen tank yang berfungsi untuk menapak dan menggerakan kendaraan tempur tank. Sebagai komponen penggerak utama maka harus memiliki sifat keamanan (safety) yang baik, serta sifat mekanis yang baik pula (tahan aus tetapi ulet). Umur pakai komponen ini hanya sekitar satu tahun sehingga digolongkan komponen yang sangat consumable. Hal ini dapat menjadi peluang bagi industri pengecoran nasional untuk memfabrikasinya. Tujuan penelitian adalah membuat komponen track link tank yang bebas cacat cor karena penyusutan, memiliki bentuk dengan dimensi dan komposisi jenis material yang sesuai serta perlakuan panas yang tepat. Metodologi penelitian yang dilakukan diawali dengan pengujian dan analisis material dari track link tank impor sebagai acuan untuk pengembangan material. Dilanjutkan pembuatan komponen track link tank melalui proses pengecoran dan perlakuan panas. Dari hasil penelitian ini diperoleh material prototipe dengan sifat mekanis yang lebih baik dibandingkan material produk impor. Cacat penyusutan dapat ditanggulangi dengan penggunaan chill atau pasir kromit pada cetakan. Perbaikan pola cetakan dilakukan untuk mengurangi ketebalan sirip sehingga dihasilkan produk cor komponen track link tank yang lebih efisien dalam penggunaan material. Kata kunci: rantai tank, baja cor paduan, cacat penyusutan, chill, pasir kromit.

Abstract

The abrasive machining process is called the grinding process using a wheel grinding. The process of abrasive machining is usually in the final stages of making a product or finishing product so that it becomes essential in making products because it determines the final quality of a product. The purpose of this research is to develop the external cylindrical grinding process in column products for one of the components for drilling machines by modifying the grinding process in the lathe machine. The study was conducted using a wheel head of tools sharpening machine that is mounted on a lathe machine. The stages of this research began with the lathe process. Then without removing the product from the lathe, the external surface cylindrical grinding process is carried out so that there is no need to be set up the workpiece because the central inertia axis of the workpiece has one axis with its geometric axis. The measurement results of the external surface cylindrical grinding process are carried out using a bird-cage strategy by dividing the measurement into six segments. From each segment, the data is collected at eight measuring points. Based on the measurement results, in sample no.3 in segments B and D there is an increase in measurement results, that is  Ø 100 + 0.018, but still below the maximum limit of Ø 100 + 0.020.

Abstract

CNC machine tools have been widely used in the process and manufacturing industries, which have the potential to increase the intensity of electrical energy consumption so that energy efficiency is needed. Energy efficiency is a necessity for the sustainability of the process and manufacturing industrial sector which will be related to energy costs and environmental factors. In order to carry out energy efficiency, it is necessary to identify the consumption of electrical energy by tracing and mapping the electrical energy flow to the components in a CNC machining center machine, so opportunities for energy savings can be known. This research was conducted by collecting data by monitoring energy consumption in stand-by, setting and cutting machine conditions. Cutting tests are carried out to determine the energy consumption of each machine component that affects energy use. After that it can be seen the energy flow pattern by classifying the energy user components into primary and secondary components. Based on the analysis of electrical energy consumption data during the cutting process, it is known that the significat energy users are the spindle motor, the axis feed motor (X, Y, Z) and the coolant motor.
