Abstract: The optimization of cutting conditions to increase the
economic performance of a machining operation is becoming increasingly
important in modern computer aided manufacturing (CAM). Optimization
strategies and CAM software for the selection of economic cutting
conditions in single pass end-milling operations on CNC machine tools
are discussed. The optimization model is developed using a deterministic
approach involving mathematical analysis and graphical representation
and based on the maximum production rate criterion. The resulting
optimization strategies apply equally for the criterion of minimum cost
per component. Numerical studies show that the optimization strategies
not only ensure the global optimum solution, but also require short
computer processing time to performing the CAM software, making them
suitable for on-line CAM applications. Experiments have demonstrated the
economic benefits of using these strategies over handbook
recommendations as well as in assessing, selecting and improving machine
tool design specifications.
