ABSTRACT
This study combined simulation and experimental tests to analyse the cutting performance of three solid carbide end mills with distinct geometries during the milling of the 7075 aluminium alloy. For the tests, three uncoated end mills were employed, which differed in rake angle, clearance angle, and helical pitch. Simulation tests revealed temperature distributions and the resultant cutting forces. The machining with a milling cutter with a higher blade angle was shown to cause an increase in the temperature in the cutting zone. However, during machining with a sharper blade of cutting tool, a decrease of cutting forces was not observed. The simulated temperature distribution on the cutting edge of the cutting tool may justify significant differences in the dynamics of changes in the cutting force components during the period of operational wear.
