Abstract
A cutting simulator based on energy approach is implemented in a process planning system, which determines the process parameters in the milling operations. The required data for the analysis is identified to minimize the discrepancy between the calculated and the measured cutting force in some reference operations. The identification function in the implemented simulator is applied to the process planning system as a module of self-management of the database. Some case studies, then, are shown to verify the simulation module in the process planning system. An application of the simulator is presented to determine the applicable cutting conditions according to the machining requirements.
