Abstract

Proses bending merupakan salah satu proses pembentukan material (metal forming) banyak digunakan di proses manufaktur. Penggunaan radius dies bending dan penyetingan sudut bending yang tidak tepat akan berdampak pada terjadinya kegagalan material dan dimensi. Penelitian ini menggunakan ekperimental dengan menggunakan material Stainless-Steel (SUS 304) dengan tebal 1.0 mm yang memenuhi standar ASTM A-240. Penelitian ini dilakukan dengan menggunakan parameter sudut bending 90^o, yang divariasikan pada radius dies sebesar 1.0 mm dan 1.3 mm. Analisis pengaruh springback telah dilakukan dengan mengatur sudut bending secara hitungan teoritis dan membandingkanya dengan pengaturan sudut aktual. Proses selanjutnya dilakukan analisis dan evaluasi untuk mencapai sudut standar . Proses bending yang menggunakan sudut bending 93^o45” dan 92^o30” berturut-turut menghasilkan nilai springback sebesar 0.98 dan 0.97. Sudut benda kerja yang dihasilkan pada saat penyetingan sudut bending 92^o30” dan 93^o45” berturut-turut adalah 91^o30” dan 90^O. Dari data ini didapatkan bahwa proses bending menggukan sudut 92^o,30” mendapatkan hasil yang lebih presisi dibandingkan dengan sudut bending teoritis 93^o45”.
