This paper presents the results and obtained mathematical models of temperature during machining
process by high speed turning as a function of processing parameters v, f, a and re. The machining process by
turning is performed on lathe type "Prvomajska TVP 250" with power P=11,2 kW and step change of number of
revolutions between n=16 and 2240 rev/min, by using ceramic cutting tool inserts type SNGN 120712- 120716-
120720 made from mixed ceramics type MC 2 (Al2O3 + TiC) and manufactured by HERTEL and tool holder type
IK.KSZNR -064 25x25 manufactured by KENNAMETAL. Workpiece material is C 1630 (DIN C 55). Cutting tool
holder is reconstructed to provide transimission of the voltage signal from the cutting tool insert. Processing
parameters are varied in range interval between v =300 and 500 m/min, f =0,16-0,30 mm/rev, a=0,5-1,0 mm and
re=1,2-2,0 mm. Average temperature is determined by using of natural thermocouple method and computer aided
research equipment. Experiments and the mathematical processing of the results are performed at the Faculty of
Mechanical Engineering in Skopje using the program CADEX combined with MATLAB. Four factorial first order
experimental plan was used.
