This treatment method is conducted on a modified EWAG
Laser Line. The machine is equipped with an Nd:YVO4
ultrashort pulsed laser of the company Time-Bandwidth
(Fuego™) which emits light in a wavelength of 1064 nm. The
laser beam is guided through a hurrySCAN II® scan head of
Scanlab with two axes and feed speeds up to 7 m/s.
The material at the cutting edge is removed by tangential
laser ablation process from the tools flank face with
reciprocating movement of the laser beam parallel to the
cutting edge; see Fig. 3 (a). The infeed in x-direction between
the three separate tangential ablation processes is 15 ȝm for
one roughing and 10 ȝm for each of the two dressing steps.
Laser parameters used: Power of 28.3 W, 800 kHz pulse
frequency, 0.6 mm/s vertical feed and 500 mm/s scanner feed,
~0.5 mm Rayleigh length, ~30 ȝm focus diameter
