Influence of End Mill Helix Angle on Surface Quality of ...
This paper deals with the influence of the end mill helix angle on the flatness and surface quality of aluminium (EN AW 6082) thinwalled parts. The three teeth solid end mills of 12 mm diameter with same and different helix angle of third tooth were designed. The tests were performed using the HSC 105 linear CNC machine and following cutting parameters: cutting speeds (800, 100 and 1200 ...
