Abstract
Cell manufacturing system which enables flexible high-mix low-volume production is required. It is required to downsize the cell itself due to the limited installation area inside the factory in cases of manufacturing for small parts. In this study, heat treatment process for small parts is focused on. Laser hardening for thin carbon steel sheet with a low power diode laser was carried out, and its hardened result and energy efficiency were investigated. As a result, through-thickness hardening for 0.5 mm thin sheet was obtained. Moreover, good energy efficiency was obtained compared to the conventional furnace hardening.
