Abstract
Recently the cost-economy is a very important component in production.
That´s
why has the modeling so great importance: we can draw conclusions from the
attempts made with computer. Thus we can produce results already on lower
cost-level.
The modeling was introduced by FORM 2D program. This is a FEM program in
which
we can examine different geometrical dates (cutting depth, cutting edge
radius).
In the program we are able to set different material quality,
machining-tool
and coolant (we also can change the feedrate). That´s why we can produce
very many kind versions and make examinations, too.
Mainly the load, the material-flow, the critical displacement, the
temperature-zones and the surface-stress can be examined. From these values
we
can draw final conclusion applied the geometry. By optimalization the
values we
are able to define how great cutting depth, cutting edge radius, feedrate
are that we work with and which machining-tool is needed
