Abstract

Proses bending tube pada dewasa ini telah mengalami banyak perkembangan. Dua metode diantaranya adalah rotary draw bending yang bersifat konvensional serta laser beam bending yang lebih modern. Selain itu, untuk mengoptimalkan proses tube bending diperlukan pengertian lebih mendalam terhadap fenomena springback, agar hasil yang didapatkan lebih presisi. Pada penelitian ini dilakukan analisis springback menggunakan Finite Element Method dengan bantuan software ANSYS 17.1. Simulasi dilakukan untuk mendapatkan hasil springback dari kedua metode yang nantinya akan dibandingkan. Penelitian pertama dilakukan dengan mensimulasikan proses laser beam bending hingga mencapai batas maksimum sudut bending yang dapat diterima. Selain itu, simulasi juga dilakukan pada metode rotary draw bending dengan parameter diameter dan ketebalan tube yang sama seperti sebelumnya namun, dengan sudut bending yang berbeda yaitu sebesar 60, 120, dan 180 yang akan digunakan sebagai data pendukung nilai springback. Dari simulasi didapatkan bahwa semakin tinggi laser power dan pass number pada laser beam bending, maka akan semakin tinggi springback yang dihasilkan namun, masih sangat kecil bila dibangdingkan dengan rotary draw bending. ============= The bending tube process in today has undergone many developments. Two methods of which are conventional rotary draw bending and laser beam bending more modern. In addition, to optimize the tube bending process required a deeper understanding of the phenomenon of springback, so that the results obtained more precision. In this research done springback analysis using Finite Element Method with help of software ANSYS 17.1. Simulation is done to get springback result from both method which will be compared. The first research was done by simulating the laser beam bending process until it reached the maximum acceptable bending angle. In addition, simulations were also performed on the rotary draw bending method with the same diameter and tube thickness parameters as before, but with different bending angles of 60, 120, and 180 which will be used as springback support data. From the simulation it was found that the higher the laser power and the pass number in the laser beam bending, the higher the springback will be, but still very small when compared to the rotary draw bending.
