Kminiak, Richard, 1984- Variability of surface quality of MDF boards at nesting milling on CNC machining centers / Richard Kminiak, Adrián Banski. -- obr., tab. -- Lit. - The article deals with the issue of nesting milling of agglomerated materials on CNC machining centers. Specifically assess the quality of the surface around the perimeter of the workpiece with the view of relative changes of feed speeds direction as a result of different positions of tools and materials. Article based on experiments in which was at 5 axis CNC machining center nesting milled 18 mm thick MDF board. In the milling process they were used router bit with one or two reversible razor blades. The experiment was carried out at manufacturer recommended intervals of cutting and feeding speeds and machining strategies. The findings of the experiment are presented via parameter arithmetic mean deviation of the surface roughness Ra. Article points out that the relative change of cutting speed direction affects this indicator. It notes that the change is average 3.4 microns in the router bit with one reversible razor blade and 1.6 microns in router bit with two reversible razor blades. Given discovery of point of view of perception of surface roughness by people can be considered negligible but in exact perception cause a need for correcting the technological parameters of the process.
