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
