The article describes mechanical treatment factors impacting on a degree of surface roughness of the cast porous materials.

Special attention focuses on such factors as cutting speed, cross feed, type of the cooling lubricants (for mechanical treatment by cutting and milling operations), cutter speed, factual speed of the table feed per minute.

Surface roughness of the samples was measured by a profile meter (model 296). A model of the first order was used for evaluating degree of the above factors’ impact and for mathematic describing of the results obtained. It is stated that spindle and cutter speed impacts mostly on the surface roughness of cast porous materials.
