Spring back analysis of pipe coil manufacturing using conventional lathe machine

Abstract

The demand for manufacturing to support the food industry, medical industry, infrastructure, energy, and transportation are soaring. Meanwhile, the capacity and capability of conventional lathe machines need to be improved, especially to the manufacturing capability of particular parts. This issue needs to be considered since lots of small manufacturing industries which have conventional lathe machine need to compete to overcome the production demand of unique parts, for example as pipe coil. In large companies, coil manufacturing is produced with a special machine. With this concept, coil manufacturing can also be made in a lathe machine. What needs to be researched is how the good product achieved. In this case, are related to the dimensions laterally and axially, because there is a spring back character on the workpiece to produce. This study analysis the spring-back of the pipe coil in which manufactured using conventional lathe machine. From this research and testing, it was found that the lathe machine can be used to make coils with pipe raw materials. It was also found that there was a size deviation in the diameter and pitch of the coil. The size deviation can be used as a coefficient to compensate for the size of the mandrel and pitch.
