N2 - Laser de-coating is a promising technology for selective coating removal to facilitate reuse of coated tools in a circular economy. It is timely to understand and optimise the quality, energy requirements and environmental footprint of the laser de-coating process. This paper reports on an investigation into process characteristics, energy demands and carbon footprints in coating removal from tungsten carbide tool inserts using high power picosecond laser sources with different pulse widths and wavelengths. The results demonstrate that although the 355 nm wavelength, 10 ps pulse width laser, has higher processing efficiency in terms of production rates, and lower specific energy for laser beam and material interaction, and results in better surface quality, the overall laser system energy consumption is much higher than that of using the 1064 nm wavelength, 150 ps pulse width laser for the removal of coatings on tungsten carbide cutting tools.
