This paper deals with the accuracy of high-speed machining by an end mill on a circular and square workpiece and the error factors involved. The results are as follows. (1) In the steady region of cutting conditions, the profile error generation is related to the following: (a) the tool mark, (b) the cutting force, (c) the cutter radius, (d) the run-out of the cutter and (e) the droop. (2) However, in the transitional region, the following errors were generated at the periphery of the workpiece: (f) the notch-type error at the outset of the machining, (g) the overshoot error and (h) the gap-type and projection-type errors at the boundary point of the quadrant. (3) The error due to run-out of the cutter increased to the square of the angular velocity of the spindle in machining. (4) The error factors of the dimensional error of the workpiece machined to be circular are classified into (a), (b), (c), (d) and (e) listed above. Also, the predicted value calculated by adding all of the above error components effected on the dimensional error is almost coincidental to the experimental value.
