“…( 8). The effect of the linear motor weight on the friction characteristic of the linear guides, and therefore the power consumption, is considered negligible due to the weak weight-friction relationship for the linear ball guides [22]. Finally, the position is commanded to the fully assembled system (the feed drive with all its components), and the power consumption is calculated through Eq.…”

“…Miura et al [17] analyzed the effect of the friction fluctuations of the linear guideway on the position deviation of the machine tool drivers, and studied the relation between the ball contact, circulation conditions and friction force. Oh et al [18] proposed a friction force model for the linear guideway, and discussed the effects of the ball size, lubricant viscosity and contact angle on the friction force distribution. Soleimanian et al [19] established the tribodynamic model of linear guideway considering the lubricant effect and two degree-of-freedom coupling.…”

This paper establishes a five degree-of-freedom nonlinear dynamic model of the linear guideway considering the carriage flexibility, which is used to analyze the ball-groove load distribution and nonlinear dynamic characteristics under the action of the complex external loads. Firstly, according to the coordinate transformation matrix, the position relation between the groove centers when the carriage is a rigid body is determined. Next, the FE simulation is used to calculate the carriage flexible deformation caused by the contact loads, and the relation curves between the contact load and the displacement of the carriage groove center are determined. Then, the final position of the groove centers considering the carriage flexibility is determined, a 5 degree-offreedom nonlinear dynamic model of the linear guideway is established. Finally, considering the possibility of the ball-groove losing contact, the Newmark-Newton numerical algorithm is established to solve the proposed dynamic model, and the proposed model is validated through experiments. Furthermore, the nonlinear static and dynamic characteristics of the linear guideway under the effect of the carriage flexibility are studied, and the effects of the design parameters on the vibration characteristics are discussed.

During the operation of the guide rail pair, the accuracy of the guide rail pair is decreased by friction and wear, and the overall performance of the machine tool is directly affected. The influence of surface micro-features of the slider raceway on the dynamic friction factor of the guide rail pair is analyzed in this paper. The relationship between the geometric characteristics of the surface micro-features and the dynamic friction factor is studied, and a prediction model of the dynamic friction factor is established. Meanwhile, the correctness and rationality of the predicted model is verified by the orthogonal experiments of the friction force. It is found that the dynamic friction factor increases with the increase of the groove depth, the height of the peaks and peak–valleys on the surface of the slider raceway. The above research provides a basis for the study of the friction and wear characteristics of guide rail pairs and lays a foundation for improving its friction and wear performance.
