Abstract

Pada saat ini, untuk membuat suatu profil sederhana pada benda kerja, kebanyakan orang masih menggunakan mesin gerinda konvensional. Penggunaan mesin gerinda konvensional pada pengerjaannya dapat memakan waktu yang relatif lama dan berpotensi menimbulkan distorsi pada permukaan benda kerja. Proses ECG (Electrochemical Grinding) memiliki beberapa kelebihan dibandingkan gerinda konvensional, di antaranya tegangan induksi yang rendah, kedalaman potong yang lebih baik, proses pengerjaan yang lebih cepat, dapat digunakan untuk berbagai jenis proses pengerjaan, serta dapat diterapkan pada segala jenis benda kerja yang bersifat konduktif. ECG mengombinasikan proses penggerindaan konvensional dengan proses ECM (Electrochemical Machining), di mana benda kerja dikerjakan melalui gerak mekanis partikel abrasif dan reaksi elektrokimia secara bersamaan. Di pasaran, mesin ECG memiliki harga yang cukup tinggi, sehingga penulis mencoba merancang bangun alat Electrochemical Grinding sederhana agar dapat digunakan oleh mahasiswa D3 Teknik Mesin Industri yang mengambil mata kuliah Pemesinan Non-Konvensional. Untuk merancang mesin ECG tersebut, diperlukan tahapan perancangan struktur, perancangan proses penggerindaan konvensional, perancangan proses ECM, pembuatan mesin ECG, serta pengujian. Hasil pengujian mesin yang telah dibuat menunjukkan nilai MRR (Material Removal Rate) untuk proses penggerindaan konvensional sebesar 138,57 mm³/min, sedangkan untuk proses ECG sebesar 330 mm³/min.

Currently, most people still use conventional grinding machines to create simple profiles on workpieces. Using a conventional grinding machine can take a relatively long time and may cause surface distortion on the workpiece. The ECG (Electrochemical Grinding) process offers several advantages over conventional grinding, including low induction voltage, greater cutting depth, faster processing, applicability to various types of machining operations, and suitability for any type of conductive workpiece. ECG combines conventional grinding with the ECM (Electrochemical Machining) process, in which the workpiece is machined through simultaneous mechanical motion of abrasive particles and electrochemical reactions. Since ECG machines are quite expensive on the market, the author attempted to design and build a simple Electrochemical Grinding device for use by D3 Industrial Mechanical Engineering students taking the Non-Conventional Machining course. Designing the ECG machine required structural design, design of the conventional grinding process, design of the ECM process, construction of the ECG machine, and testing. The test results showed an MRR (Material Removal Rate) of 138.57 mm³/min for conventional grinding and 330 mm³/min for the ECG process.
