Abstract
This paper deals with testing and investigation of
changeable coated carbide cutting inserts with the
hard rough face milling process. All realized
cutting tests have been performed on CNC vertical
milling machine tool at Department of Engineering
in Trencin within the scope of the European Union
Foundation ITMS project code 26110230099. The
main aim of this paper is to focus experimental
investigation on the impact of the various applied
values of cutting speeds while hard machining the
material Hardox 500. Testing cutting tool
materials used in this research are coated
cemented carbide changeable inserts produced by
DORMERPRAMET Company. Tested machined
material was hard abrasion resistant steel Hardox
500. The cutting speeds (55.7 m.min-1
, 78.5 m.min-1
and 111 m.min-1
) are investigated with variable
parameters, whereas the cutting depth and feed
rate are constant parameters. The pictures of new
and worn changeable cutting inserts geometry and
the graph of dependence on variable cutting speed
are shown as a result of this realized investigation
