Effect of Clearance on the Height of (Burr) on Arm Rear Brake Type 45p at Pt. Xyz Karawang

Abstract

Arm rear break is one component of vehicle spare parts found on motorcycles. This component is made using a forming process, where one of the parameters that affects the failure is the clearance value. Therefore, the purpose of this study was to determine the effect of clearance on the burr height of the 45P Arm Rear Break. The arm rear break is made of sheet metal plate material with a thickness of 2.6 mm through the forming process and variations in clearance numbers of 4%, 5% and 6%. For the punching process, a 12 mm diameter punch knife was used. The result of this research is that the highest bar value is produced by 6% clearance of 0.29 mm, then 5% clearance of 0.23 mm and 4% clearance of 0.17 mm.

Analisis Pengaruh Clearance terhadap Hasil Potong pada Proses Stamping Produk Member Floor Side Inner LH

“…SPCC dapat digunakan untuk pembuatan dies karena memiliki kualitas permukaan yang lebih baik dan lebih tipis dengan ukuran yang dibentuk dapat lebih tepat [7]. Jika masih dibiarkan pengaruh clearance akan terus bertambah seiring meningkatnya produk cacat yang diakibatkan masalah dalam proses produksinya [8].…”
