Computer-aided constrained optimization analyses and strategies for multipass helical tooth milling operations

Abstract

The development of computer-aided constrained optimization analyses and strategies for multipass peripheral and end-milling operations are outlined and discussed. The constrained optimization is based on criteria typified by the maximum production rate and includes a range of practical constraints of relevance to rough milling such as the machine tool limiting power, torque, feed force and feed-speed boundaries. It is shown that a combination of mathematical optimization analyses and limited use of numerical search techniques provides clearly defined computer-aided strategies which guarantee the final global optimum solutions. Simulation studies have verified the software and demonstrated the superiority of multipass over single pass
