The paper is an overview of the present state of the art and
of the research and development results concerning the finishing
Finishing processes are final machining processes which use fine
grit abrasive as the cutting medium. The processes are widely used
in industry in order to improve the surface topography to increase
the bearing area and load-carrying capacity.
The main characteristic of finishing abrasive machining processes is
that these processes are more random than many other machining
processes. Tribology offers a good approach for describing the main
characteristic of abrasive finishing processes and offers the
ability to predict some of the outputs of the processes like
abrasion rate or the surface quality.
The basic concepts and recent developments in lapping, polishing and
fretting as well as the significance of surface metrology
(especially the 3D methods) in finishing processes are presented.
