Constrained optimization strategies and computer flow charts for single-pass rough peripheral milling on NC/CNC and conventional machine tools are presented and discussed. Various practical machine tool constraints have been considered, namely the maximum available power, torque and feed force, and feed speed and cutting speed limits. The optimization strategies for this common operation have been found to be very complex and require computer assistance. A comparison of handbook recommended and optimal solutions has highlighted the significant benefits of using the latter, and the need for minimizing the component loading time and cost to maximize such benefits.
