“…e interface is defined in polar coordinates, and the center point of the polar coordinate system is concentric with the center of the circular hole nested in the specialshaped hole. Among them, the coordinates of the holemaking machine tool from 2 to 6 are the parameters obtained automatically by the 3D detection auxiliary positioning module, and the other parameters are obtained by the operator manually editing the data table [20][21][22].…”

In order to further improve the collaborative control efficiency of the electrical system of the laser CNC machine tool, an electrical system based on the ultrafast laser CNC machine tool is proposed. The design of the collaborative control scheme is discussed from three aspects: the overall control scheme design, hardware structure design, and control software implementation of the electrical system of the laser numerical control machine tool. The experimental results show that the length of the metal sheet processed by the electrical system of the laser CNC machine tool is 5.3 cm and the width is about 3.6 cm, and the actual processing aperture size will also change according to the set number of variable radius turns, and more precise processing can be enabled in the online test. The research results show that this electrical collaborative control system scheme has strong practicability and feasibility. With the help of system upgrades and optimization, the efficient integration of laser processing technology and numerical control technology can be better achieved. It should be noted that the machining process of the machine tool is also required to make in-depth improvements, which can maximize the operating efficiency and machining accuracy of the electrical system of the CNC machine tool. The laser CNC machine tool researched and developed in this paper verifies the rationality and feasibility of the collaborative control scheme through practical experiments, which can meet the processing requirements and realize the integration of laser processing technology and numerical control technology. High machining efficiency and machining accuracy.

This paper presents a turntable system, which can be used for torque, angle calibration. Based on the design of the turntable,the calibration experiment of the turntable system is carried out by using photoelectric autocollimator, and an error harmonic compensation model was established to compensate the angle measurement error of the turntable. The angle measurement accuracy of the designed turntable system is improved.

“…Furthermore, the theory of the laser tracker based on the multi-lateration method are also proposed in [8]. Moreover, Wang et al [9] also proposed a new method for separating geometric errors of the rotation axis through a laser tracker. Aguado studied the quadrilateral, trilateral measurement , least squares adjustment and different self-calibration procedures measurement of the laser tracker, as well as the range and applicability of each method relative to the laser tracker's measurement noise [10].…”

The geometrical errors are affected by many factors for a multi-axis machine tool, such as materials, manufacturing, assembly, measurement, control, and environmental. The geometric error will eventually be reflected in the accuracy of the workpiece; therefore, for each part of the machine tool, the measurement of geometric error is essential. Most geometrical errors are measured separately for each axis. The single geometrical error measurement method is time-consuming. The multiple geometric error measurement methods have some limitations based on different instruments. Laser tracker based on GPS (Global Positioning System) positioning principle can measure the dimensional coordinate. Thus, the laser tracker measured geometric errors in high efficiency, high precision, wide range. This paper introduces the method of measuring the multi-axis machine geometrical error by using a laser tracker with a 1280mm×1280mm×240mm range and compares the measurement result from the traditional method. The results show the laser tracker method has high measurement accuracy, and rapid measurement and compensation of geometrical errors are achievable on a large-stroke machine tools.
