The Machining dynamic team performs research and develops methods to predict, diagnose and control machining vibrations and applies these results on industrial applications.

Machining Dynamics Group performs research in the following areas:

  • Predictive Models
  • Spindle Dynamics
  • Workpiece Dynamics
  • Vibration Control
  • Robotic, Robotic Assisted Milling
  • Composite Milling
  • Micro milling


Recent projects include developing process models for the dynamics of parallel machining; surface roughness predictions for milling; and a set-up for rotating frequency response function measurements. We also employ commercial solutions where they are available.
Machining Dynamics Group provides services in the following areas:


Process Optimisation - The Group applies its expertise in optimisation of the machining processes of companies for reduced cycle time and increased quality.
Benchmarking - The group objectively benchmarks the available technologies for a given machining requirement for the benefit of the customer.
Training - The group delivers in internal and external training in machining dynamics area. The trainings cover tap testing and mechanics and dynamics of machining processes.
