The manufacturing test part applications are essential for representations of machines' capabilities. Commonly used NAS979 has been known to insufficiently evaluate the combination motions of rotary axes. Thus, a new test part, S part, has been presented to satisfy the increasing demand of a five-axis machine. In this paper, the model of S part is described in detail, which presents more characteristics in three-dimensional surface contours. According to the kinematics analysis, the speed of each axis and feed rate falls down and rises up on several positions. Each axis reverses the motion during the machining. Therefore, the S part makes high requirement on machine's dynamic response.
