Sažetak

In the technological planning of hard machining procedures, several factors of the component have to be considered. One factor is the system of geometrical dimensions of the components. The potential procedures capable of providing the required accuracy and quality specified to the surfaces, and/or their (economical) efficiency can also be influenced by the geometrical dimensions. Beyond the generally prevailing time study, in the present paper the material removal rate and the surface rate are investigated referring to hardened internal cylindrical surfaces. These parameters are referred to the unit operation time. The values of the parameters are analysed at different bore geometries. The investigations are performed for hard machining procedures with different inserts, as well as a combined hard machining and grinding procedure, and values are given with conventional (traverse) grinding as the basis of the comparison.
