Behaviors of Cutting Force and Acoustic Emission in Different Helix Angle Endmilling

Kim Wom Il,Wang Duck Hyun,Kim Young Soo,


This study shows how the change of helix angle of different helix angle end mill affects machining accurracy. It was verified that cutting force are remarkably low when endmill has helix angle of different helix angle 250, 310, 370 and AE signal have less reationshap with the change of helix angle. Moreover, as the number of rotations are increases, the AE signal increased with the proportion to the number but cutting force are inversely proportional to the rotation.
