Abstract
Gerinda datar merupakan proses pemesinan yang menggunakan serbuk abrasif dalam bentuk roda gerinda berkecepatan tinggi untuk memotong permukaan benda kerja. Penelitian ini bertujuan memperoleh kombinasi level variabel proses yang optimum serta meminimalkan respons getaran pada sumbu x, getaran pada sumbu z, dan kekasaran permukaan. Penelitian menggunakan metode desain eksperimen Taguchi dengan orthogonal array L32 (2¹ × 4²) yang diintegrasikan dengan metode Grey Relational Analysis (GRA) untuk mengoptimalkan karakteristik multirespons dari hasil percobaan. Variabel proses yang digunakan meliputi cross feed (CF) sebesar 5 dan 15 mm/langkah, tangential speed (TS) sebesar 11, 92, 173, dan 256 mm/s, serta wheel speed (WS) sebesar 1500, 2000, 2500, dan 3000 rpm. Hasil penelitian menunjukkan bahwa kontribusi masing-masing faktor dalam mengurangi variasi respons secara simultan berturut-turut adalah cross feed sebesar 37,17%, tangential speed sebesar 29,94%, dan wheel speed sebesar 20,90%. Hasil optimasi yang telah divalidasi melalui eksperimen konfirmasi menunjukkan bahwa kombinasi parameter proses yang menghasilkan respons optimum adalah cross feed 5 mm/langkah, tangential speed 11 mm/s, dan wheel speed 3000 rpm.

Surface grinding is a machining process that uses abrasive particles in the form of a high-speed grinding wheel to remove material from the surface of a workpiece. This study aimed to determine the optimum combination of process parameters while minimizing the response variables of x-axis vibration, z-axis vibration, and surface roughness. The experimental design employed the Taguchi method with an L32 (2¹ × 4²) orthogonal array integrated with the Grey Relational Analysis (GRA) method to optimize multiple response characteristics simultaneously. The process variables investigated were cross feed (CF) of 5 and 15 mm/stroke, tangential speed (TS) of 11, 92, 173, and 256 mm/s, and wheel speed (WS) of 1500, 2000, 2500, and 3000 rpm. The experimental results showed that the contributions of the process parameters in reducing the overall response variation were 37.17% for cross feed, 29.94% for tangential speed, and 20.90% for wheel speed. The optimization results, validated through confirmation experiments, indicated that the optimum process parameter combination consisted of a cross feed of 5 mm/stroke, a tangential speed of 11 mm/s, and a wheel speed of 3000 rpm.
