| dc.description.abstract | The objective of this work is to generate irregular, smooth,
adaptive laser scan trajectories for pulsed laser micro polishing
(PL?P). Traditionally PL?P, like other surface finishing
processes has used zigzag scan paths. Zigzag trajectories
are simple in nature, are comprised of sharp turns, the dynamics
of the positioning system are not taken into account,
and more importantly are not adaptable because the path
generation is independent of surface condition. In this paper,
the authors present a scan trajectory generation scheme that
can overcome these limitations. These trajectories are based
on the artificial potential fields method of path planning that
take the surface condition into account. Computer simulations
are presented to illustrate the characteristics of the path and
guidelines are developed for choosing the trajectory generation
parameters. Finally, smooth, irregular scan trajectories
are generated for a micro end milled Ti6Al4V surface that has
a feature that needs no polishing, thus illustrating the versatility
of the trajectory generations scheme. | en |
