Computer-aided economic optimization of end-milling operations

Abstract

Optimization analysis, strategy and CAM software for single pass end-milling on CNC machine tools are outlined and discussed based on criteria typified by the maximum production rate and allowing for a range of machine tool and component surface roughness constraints. It is shown that the deterministic optimization approach involving mathematical analyses of constrained economic trends and their graphical representation on the feed-speed domain provides a deeper understanding of the influences of constraints and a clearly defined strategy which guarantees the global optimum solutions. Numerical simulation studies have amply demonstrated the economic benefits of using this strategy over handbook recommendations as well as in assessing, selecting and improving machine tool design specifications.
