Abstract

Polyurethane is used for packaging valuables. However, it is challenging to cut polyurethane while maintaining the exact form of the workpiece because of its high elasticity. Therefore, it is essential to precisely determine the machining parameters for maintaining the form accuracy rather than the processing speed. In this study, the machining conditions that could maintain the contact surface accuracy were determined so that the packaging block could stably support the contents. Based on the characteristics of the Taguchi technique and experimentally applied initial machining conditions, the optimum machining conditions such as the spindle speed, feed rate, step over, and tool path pattern, considering the machining stability and machined surface integrity, were determined.


Keywords: Packaging valuables, Polyurethane foam, Form accuracy, Taguchi technique, Machining conditions, Optimum conditions
