Theme I

Theme I:   Digital Machining
(Theme Leader: Kaan Erkorkmaz, University of Waterloo)


Contribution towards common objectives

CANRIMT Phase 1 had successfully developed and commercialized some of the most accurate digital models of a large class of machining operations, like 5-axis milling, turning, boring, drilling, and micro-machining. During Phase 2, Theme I will extend the virtualisation studies well beyond these configurations, targeting some of the most important challenging, and newly emerging machining processes identified by the Network’s industrial partners. Theme I will also explore optimum synergies between Additive Manufacturing (AM) and machining, and will investigate new computational methods to streamline some of the most critical and intensive calculations, such as Cutter-Workpiece Engagement (CWE), required for digital machining simulation.

Background

  • Digital modeling of complex machining operations on multi-functional machine tools.
  • Intelligent Integration of Additive Manufacturing (AM) and Machining Processes.
  • Cutter-Workpiece Engagement (CWE) Calculation

Role of Theme I in the overall Network: 

  • Develop digital models of emerging machining operations:
    • mechanics and dynamics of turn-milling, gear machining, thread turning, and orbital milling
    • modeling of hybrid and sequential additive manufacturing (AM)/machining operations
    • efficient computation models for cutter-work piece engagements along the toolpath
