Abstract. The paper is an overview of the present state of the art and of the research and development results concerning the finishing abrasive processes.
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.
 

Keywords: finishing, abrasion, lapping, polishing, fretting
