Dependence of surrface roughness of machined surface of coating cutting tool

In arrticle results of researches of a roughness of a surface of materials from some steels and grey pig-iron in process turning by cutters with plates from a firm alloy of type are resulted. The covering has been put on surfaces of these plates by method CVD of a various thickness. Coverings ((TiCr)N and (NbTiZr)N were investigated. Mathematical dependences of change of a roughness of the processed surface of the specifieed materials on a kind of a covering, its thhickness and parametre of a mode of cutting are defefined.

Keywords: plates by method CVD, steels and greey pig-iron by cutters, a roughness of a surface of materials process turning.
