The machining test of cone-frustum specified in NAS 979 is only one method to evaluate the machining accuracy of five-axis machining centers. This paper analyzes the influence of the apex angle, inclination angle and center position of the cone frustum on the moving range and feed velocity of five axes when the cone-frustum is machined under simultaneous five-axis control. When the center of the cone moves along the X direction it gives a singular condition that the X-axis or Z-axis does not move. The offset along the Y direction gives larger moving range of liner axes and independent reversal points in every axis. The larger apex angle gives the less influence on motion trajectories of the A-axis. Therefore, it is recommended to move the center position of cone frustum along the Y direction.
