Abstract


As the profile-milling approach to machine end-mill flutes in 4-axis CNC turn-milling machines is developed in the first part of this article, the cutters’ orientations and locations (path) can now be obtained at any moment of the machining. Knowing the cutter’s path, a machining simulation model based on the envelope theory is developed in this part. The model generates a swept surface very essential in performing the simulation and in obtaining the flutes. The model also introduces a simple method to control the core radius of the end-mills and to investigate the effect of type and geometry of cutters on the final shapes of the flutes. Several case studies are presented, and the profile-milling approach of the end-mill flutes in 4-axis CNC turn-milling machines is verified. Therefore, this approach is expected to contribute to the CNC programming techniques of the end-mill flutes in multi-axis profile-milling processes.
