The complex surface machining quality is related to the capacity of the control system, servo drive and mechanical transmission infive-axis CNC machining. The unsuitable parameters result in surface contour errors and other processing abnormal phenomena such astool marks and corrugated surface. In this paper a twisted ruled surface in flank milling is analyzed. The construction features of surfaceand the tool path characteristic of the specimen are listed. The surface cutting velocity is deduced considering the constraints of the acceleration,jerk and other control parameters and the smoothness is modeled. The individual tracking error acquired from servo feed systemmodel is converted to the contour error by homogeneous transformation matrix and Frenet frame, and abnormal tool marks in flank millingare suggested. The cutting experiments conform to simulation; the effect of the dynamic indicators of the CNC machine tool is exploredby the abnormal marks on the machined parts. This approach provides a support for designing specimens and investigating machinetool dynamics performance in working accuracy test.
