“…In multi-axis servo motion systems, the accuracy of single-axis positioning and the synergy between axes are closely related to the overall contour accuracy. Before suppressing the general spatial contour error, it is necessary to ensure the positioning accuracy of each axis and then consider the dynamic characteristics and parameter matching issues between axes [6,7]. In recent years, scholars have conducted extensive research on the accuracy of single-axis positioning, such as feedforward control [8,9], active disturbance rejection control [10], adaptive control [11], etc.…”

With the widespread application of multi-axis machining in the industrial manufacturing, aerospace, and military equipment sectors, the demand for machining ultra-precision components has been steadily increasing. Contour errors directly impact the quality of machined parts. In conventional multi-axis motion control systems based on cross-coupling, it is conventionally assumed that all individual axes are of equal significance during machine processing. However, in practical machining scenarios, diverse machining trajectories and accuracy requirements give rise to distinct control necessities for each axis. This complication leads to challenges in ensuring a consistent single-plane contour, thereby constraining the elevation of the overall contour accuracy. To address this issue, this study proposes a multi-axis contour error suppression method based on composite hierarchical control. The approach advocated in this paper initially ensures the precision of single-axis position control through the development of an advanced S-shaped function-based sliding-mode disturbance observer. Building on this foundation, the three-dimensional spatial contour is segregated into upper and lower layers. Subsequently, dedicated fuzzy PID cross-coupling controllers are devised for each layer. The experimental outcomes substantiate that in comparison to conventional cross-coupling control methods, the method introduced in this study, rooted in composite hierarchical control, not only guarantees the accuracy of single-plane contours but also further enhances the overall contour precision.

Two rotating axes of the five-axis machine tools complicate the kinematics, which increases the difficulty of trajectory planning of five-axis CNC machining. In the process of machining a free-form surface with a ball-head cutter, the tool is required to follow the tool tip path of the surface and the restriction of tool orientation is only constrained within a certain range. This paper proposes a planning algorithm based on differential vector optimization for generating a smooth trajectory of each axis for five-axis machining. Firstly, the kinematic model of the five-axis CNC machine tool and the Jacobian matrix are built. Secondly, the optimization objectives combined with the smoothness optimization requirements and the limits of the tool axis vector are established. Then, the trajectory of the moving axis by integrating the optimized differential vector is generated. At last, a waveform surface is machined based on VERICUT software and a five-axis machine with the trajectory generated by the proposed method. To prove the feasibility and superiority of the method, a simulation based on VERICUT and no-load experiments are conducted in an A-C type five-axis CNC machine. The simulation and experiments verify the smoothness and optimal of the proposed path planning method.

“…However, the actual tool contact position was not controlled. Yuan et al [20] considered the planning of tool axis vector and contact position between different tools at the same time, designed the tool contact path based on smooth tool vector without collision interference, and generated smooth path of plane end milling tool.

Post-processing is an important technology in transferring information between CAM software and CNC system. At present, the traditional five-axis machine tool cannot satisfy the requirements of high precision and efficiency in the manufacture of complex parts due to its single function. The auxiliary rotary spindle, auxiliary linear axis, and power tool rest are added on the basis of the traditional five-axis machine tool to solve the technical bottleneck problem. Thus, the machine tool with the composite function of turning and milling is established. The control of the motion chain and the numerical control system of the turn-milling composite machine tool is more complex than that of the traditional five-axis machine tool, and the development of the post-processing is also more difficult. This study investigates the development of post-processing of a nine-axis five-linkage turn-milling composite machine tool (PUMASMX2600ST). First, the kinematic chain and coordinate system of the turning and milling function are established, respectively, according to the function division of the machine tool, and the inverse kinematic model is solved by the kinematic coordinate transformation. Second, a special post-processing software with turning and milling functions is developed using Visual Basic language. Finally, a type of blade root milling tool is used as the specimen for simulation and actual cutting verification. Experiments show that the special processor is correct and reasonable, and it can satisfy the requirements of the machine tool.
