“…The homogeneous transformation matrix (HTM) [7][8][9][10] based on the theory of rigid multibody kinematics [11][12][13] is used to establish the error transmission between cutter location and tool orientation. Multi-body system theory 14 based on the mathematical algorithm of the HTM broadens its application scenarios and convenience. In recent years, geometric error modeling theories for multi-axis machine tools have experienced a quick development.…”

For the purpose that the multi-axis machine tools can machine workpieces flexibly and accurately, it is important to ensure that each axis of the machine tool can be linked with each other, and the geometric tolerances are within their required range. However, each tolerance is not only related to its own kinematic axis, but also affected by the comprehensive influence of other kinematic axes, which brings great difficulties to the modeling of geometric tolerances. This paper focus on developing a modeling methodology to describe the relationship between the range of machining geometric tolerance and the motional domain of machine tool axe based on an improved Jacobian-Torsor theory. General formulas for the expression of the geometric tolerances are derived. Experiments are carried out on five four-axis machine tools, type CNC-SH50, to verify the effectiveness of the proposed kinematic Jacobian-Torsor model in dealing with the interaction analysis of geometric tolerances.

“…The dynamic and static error of the machine tool will restrict the motion accuracy of the machine tool: in more detail, the geometric error, the error caused by the cutting force and the thermal error have a greater impact on the accuracy, 1,2,3 therefore, to improve the machining accuracy of the machine tool, the overall error should be controlled.…”

Positioning accuracy is an important index used to indicate the accuracy of the moving parts in a machine tool under the control of CNC system. In order to improve positioning accuracy, error compensation is needed. Existing error compensation methods include model compensation and non-model compensation. However, due to the simplification of the error mapping model, some error parameters cannot be mapped to the model, so only part of the error parameters can be modified, and the compensation result is not ideal. In the present work, based on the thinking method of finite element, a non-model compensation method is used to compensate for the geometric error of a one-translational two-rotational (1T2R) power head (which is independently developed by Tianjin University). First, the pose error prediction model will be established, and the error of any point in the workspace can be predicted. The input correction method is then proposed to compensate for the pose error. Finally, both the proposed error prediction model and error compensation method are verified by simulation and experiment, and the results show that the proposed method can reduce the error of this 1T2R power head.
