A Method for Using a Virtual Machining Simulation to Consider Both Equivalent CO2Emissions and Machining Costs in Determining Cutting Conditions

An evaluation system for calculating equivalent CO 2 emissions and machining costs is developed using an activity-based model. The system can evaluate a machining process from an NC program, workpiece information, and cutting tool information, and it can then calculate accurate equivalent CO 2 emissions and the machining cost. The cutting speed of an end mill operation is evaluated in terms of the equivalent CO 2 emission and the machining cost. Based on the results, optimal cutting conditions are determined to minimize the equivalent CO 2 emissions and the machining cost to the extent possible.
