This paper deals with the influence of feed rate on the quality of the machined surface, especially surface roughness. The experiment was carried at cutting tool HURCO VMX t30 at with respect of the following cutting parameters: cutting speed of 250; 350; 450; 550 and 850 m.min-1, feed 0,1; 0,5 and 1,0 mm / tooth. Machining went by five-tooth cutter FF FW D50-22-05 and cutting inserts FF WOMT 060212 TM IC908 on the materials 1.2343 (19 552) and 1.1191 (12 050). Evaluated were parameters Ra - arithmetical mean roughness deviation and Rz - the largest inequalities height profile in the transverse direction and the longitudinal direction of machining. As a result will be the structural equations that describe the character depending on the cut surface roughness parameters.
