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

Abstract

An evaluation system for calculating equivalent CO2emissions 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 CO2emissions and the machining cost. The cutting speed of an end mill operation is evaluated in terms of the equivalent CO2emission and the machining cost. Based on the results, optimal cutting conditions are determined to minimize the equivalent CO2emissions and the machining cost to the extent possible.
