Abstract
Two test specimens of ABNT 1020 steel were machined in order to evaluate the results of the arithmetic mean deviation and temperature output parameters, varying the cut-off direction between up-milling and dow-nmilling frontal. Realization of 10 passes in each body of evidence corresponding to each movement. The test was performed without cutting fluid and new cutting edges were used for each test specimen. The following cutting parameters were used: depth of cut (ap) of 1mm, feed per tooth (fz) 0.12 mm / edge, cutting speed (vc) 160 m / min, penetration of work (ae) 30 mm and diameter of the cutter (Dc) of Ø 63 mm. The tool applied to the tests was a Ø 63 mm milling cutter with 5 uncoated cermented carbide tool of class P 25-40. At each pass for both movements the mean arithmetic deviation was recorded and the temperature was monitored during milling For arithmetic mean deviation the up-milling t movement had lower values in relation to the dow-nmilling, in the temperature parameter the down-milling movement presented lower values when compared with the up-milling.
