New end mills (4 flutes) with irregular tooth pitch have been proposed. These irregular end mills can reduce machining error because the instantaneous deflection of the end mills change for each cutting edge and one edge with smallest deflection can produce better surface than cutting by regular end mills. The effectiveness of 9 types of these end mills have been examined based on computer simulation, and two of them have been examined further by experimental cutting. The results obtained are as follows : maximum value of machining error is reduced by the irregular end mills. Especially the one with left helical teeth shows considerable reduction of machining error. Both of the two irregular end mills used in experiments have shown higher stability against relative vibration between the tool and the workpiece.
