High precision smart machining has tremendous potential and is becoming the next generation of precision machining technology. Smart machining processes will enable a level of adaptability, which also lead to high process reliability, high precision, machining process optimization, plug-and-produce operations, and bespoke high value applications. 


This presentation will present some innovative design concepts and, in particular, the development of three types of smart cutting tools: a force-based smart cutting tool, a temperature-based internally-cooled smart cutting tool, and a fast tool servo (FTS) as required for precision and micro manufacturing purposes.  Practical implementation and application issues for these smart cutting tools are explored and discussed, considering the requirements for smart machining from a number of industrial applications, such as contamination-free machining, machining of tool-wear-prone Si-based infra-red devices and medical applications.  Additional research on smart tooling implementation aspects will also be presented including: (a) plug-and-produce design principle, (b) novel cutting force modelling and the associated implementation algorithms, (c) piezoelectric film and surface acoustic wave transducers to measure cutting forces, (d) critical cutting temperature reduction and control in real-time machining, (e) in-process calibration through machining trials, (f) Multi-physics based design and analysis of smart cutting tools, and (g) application exemplars on smart machining.


The presentation will conclude with further discussion on the potentials and applications of smart tooling development for a broader manufacturing
