Abstract
The aim of this paper is to theoretically evaluate the process of machining metallic materials and at the same time evaluate the cost reduction defined by the evaluation criteria. When cutting conditions and tool durability optimizing, it is necessary to apply certain optimizing criterion within certain restraining conditions. [12] The restrictions are given by technical parameters of a machine, tool, machined material, required quality of machined surface etc. The essential economic criterion is the amount of production cost. The notion of “machinability of materials” is a complex of characteristics of the machined material which is monitored in the view of its fitness for the production in a certain way of machining.

Cutting speed when considering certain cutting edge durability, surface roughness, degree of splinter deformation and resultant splinter shape and its proportions are utilized as evaluation of machinability indexes
The criterion for minimal production costs can be given by the relation: Nc = Ns + Nn + Nm where: N – production costs to calculate an operational section,[€], Ns - costs to machine labor per an operational section, [€], Nn – costs to machines related to the operational section, [€], Nvn – costs to exchange or offset of a worn-out device related to the operational section, [€]
