Machining and Machinability Research
 Group

Metal cutting is one of the most widely used manufacturing processes and plays significant roles in product manufacture as well as the overall economy. Process complications vary with different systems, but in general, establishing the machinability of a given material is important considering the significant cost of tooling and manufacturing lead times. In spite of the extensive research attention for the past sixty years, and consequent theoretical, analytical, experimental and numerical understanding of the processes, research related to machinability is challenging considering the multiple factors influencing the mechanisms and mechanics of metal cutting.  While the smallness of the scale poses limitations to experimental evaluation, developments of new materials, particularly with poor machinability offer renewed challenges to research in metal cutting and the Machining and Machinability Research Centre at AUT targets these issues, with particular reference to:

  • Machining and machinability of duplex stainless steels and titanium alloys
  • Numerical modelling of thermo-mechanical transformations in machining
  • Experimental methods for metal cutting research
