A study on the behaviors of acoustic emission and cutting force signals in different helix angle endmillingz

부등각 엔드밀 가공시 음향방출신호와 절삭력 거동에 관한 연구

This study shows how the change of helix angle for different helix angle end mill affects machining accuracy. It was verified that cutting forces are remarkably low when endmill has helix angle of different helix angle $25^{\circ}\;, \; 31^{\circ}\; , \; 37^{\circ}$and AE signals have less relationship with the chance of helix angle Moreover, as the number of rotations are increased, the AE signals are increased with the proportion to the number but cutting forces are inversely proportional to the rotation.
