Abstract

Resistance spot welding (RSW) menjadi salah satu pilar utama dalam manufaktur otomotif, khususnya dalam perakitan badan kendaraan. Studi ini menyelidiki kinerja dan efisiensi dari sistem prototipe resistance spot welding yang baru dirancang untuk perakitan badan kendaraan. Metodologi penelitian melibatkan pengujian dan evaluasi yang ketat untuk mengukur efektivitas sistem dalam hal kualitas las, dan kekuatan. Berbagai parameter seperti arus pengelasan, waktu, dan gaya elektroda secara sistematis diperiksa untuk mengoptimalkan proses pengelasan. Selain itu, analisis komparatif dilakukan antara sistem RSW prototipe dan metode pengelasan konvensional untuk menilai superioritasnya dalam hal kinerja dan efektivitas biaya. Temuan ini memberikan wawasan berharga tentang kelayakan dan potensi keuntungan mengadopsi teknologi RSW prototipe dalam manufaktur otomotif, membuka jalan bagi peningkatan produktivitas dan kualitas dalam proses perakitan badan kendaraan.

Abstract

Drilling is a process of making holes by pressing a rotating chisel on the workpiece. The machining process occurs interaction between the drill bit and the workpiece where the workpiece is cut while the drill bit experiences friction. RPM variations are needed to adjust the drilling to the material being drilled, the size of the drill bit, and the purpose of drilling. testing variations in engine speed against drilling time, using an ST 40 iron workpiece measuring 40x150x8 mm, with the same load weighing 1.9 kg, using a 12 mm diameter drill bit. drilling results the faster the engine speed (rpm) will produce a faster drilling process time, but the resulting threaded hole is not good because the engine speed does not match the drill bit. While the drilling results the slower the engine speed (rpm) will produce a slow drilling process time, but the resulting threaded hole is good because the engine speed matches the drill bit used.
