254-260This paper deals with analysis of wide-range dependence of cutting parameters and describes and interprets
physical-mechanical-thermal changes in such range. The paper experimentally evaluates the coating impact on cutting and deformation process, on shape and structure of the chip, nature of the tool wear and tool life and surface roughness. Moreover, the paper analyses and evaluates the advantages of the selected monolayer and multilayer coatings in terms of roughness of the work-piece and tool wear. Influence of coating thickness and temperature in coated and uncoated cutting tool is evaluated by numerical simulation
