Abstract
Reconfiguration is an important manufacturing step that allows the system or the machine to change its function or capacity when introducing a new part family. The purpose of this study is to present a method for determining the
reconfiguration ramp-cost for the reconfigurable guillotine shear and bending press machine. To achieve this, the development of reconfiguration ramp-up and costing models was demonstrated. This focuses on the analysis of the ramp-up time and the cost of reconfiguring a dual functional reconfigurable guillotine shear and bending press machine. This includes the conversion of the machine from one function to another and length variation as well as the identification of the ramp-up characteristics and reconfiguration requirements for the machine conversion. From the findings of this study, the conversion cost reduces from $0.3965 during the manual operation to $0.0264 for the automatic operation. This amounts to 93.34% reduction in the conversion cost. In addition, the reconfiguration ramp-up cost reduced from $9:05 for the manual process to $8:68 for the automatic process, which amounts to a 4.08% reduction in the cost. It is expected that the findings of this study will allow manufacturing industries to achieve cost-effectiveness per unit time during reconfiguration operations for improved profitability.
