Simulation of the Milling Process for CAM Applications

CAD/CAM systems require technical data to model the tool and machined workpiece behavior during the cutting process. The large varieties of machining input data prevent exhaustive studies for each machining operation. The purpose of this paper is to analyze the most influent parameters (ie. rake angle, cutting speed and hone radius) on cutting force during the milling process in order to limit experiment testing while providing accurate data for the CAD/CAM requirement. Simulation results based on modified Altan’s approach are compared with experimental measurement for three different materials (AISI P20, AISI H11 and 2024 aeronautic alloy) and varying insert geometries (different rake angles and hone radius) are tested.Copyright © 2003 by ASME
