| Abstract: | Optimization analyses and strategies for drilling operations on CNC machine tools with plane rake faced (PRF) twist drills are presented using a deterministic optimization approach. The optimization is based on criteria typified by maximum production rate while allowing for a range of practical constraints. The optimization analyses result in a deeper understanding of the effect of the constraints and a clearly defined optimization strategy that guarantees the global optimum solution. A numerical study is finally carried out to assess the optimization model and demonstrate the economic benefits of using this model over handbook recommendations in selecting the drilling parameters. |
