“…The position and movement of objects in the environment are inextricably linked with the turns and rotations of objects. In the engineering practice of creating, manufacturing and operating aircraft, spacecraft, ships and other mechanical systems, the concept of six degrees of freedom (6DoF) is used [37][38][39][40]. It determines the number of independent parameters that characterize the configuration, as well as the possibility of changing the relative orientation of objects in the environment.…”

Introduction: The main problems hindering the creation of fully automatic systems of design of parts and technologies of their production are considered. The search for and formalization of regularities and relationships between the design parameters of parts and the technology of their production is an urgent task. At the same time, it has not yet been possible to create a unified general theory of geometric construction and transformation of objects at the macro level. Purpose: To show and formulate the key problems of formalizing the design process and identify possible ways to solve them. Methods: The study uses a wide range of methods of algebra, geometry, and discrete mathematics, as well as the main provisions of the geometry of non-ideal objects. Results: The need for fundamental laws of generation of geometric configurations and their elements is a key formalization problem. The geometry of non-ideal objects allows us to formally solve these problems. A geometric object is represented in six-dimensional space (three linear and three angular dimensions) with binary non-uniform metrics. The considered geometry has a principal possibility to formally generate geometric configurations of objects and their elements. The geometrical structure of a part is unambiguously connected with a set of technological schemes providing the mutual arrangement of surfaces during machining. Rules for the formal generation of a complete set of technological structures that are guaranteed to provide the specified parameters during the machining of parts. Conclusion: Sets of surfaces and relations between them define the individual structure of geometric configuration for each specific object. This individuality can be effectively used for the formal recognition of geometric objects. The geometry of non-ideal objects can serve as a fundamental basis for the formal theory of the creation of original technological processes of their processing.

“…And for the direct measurement method,in order to realize the measurement of the single error of the machine tool, the optical instrument is mainly used to identify the changes in the reflected optical path of the optical mirror group as the machine tool moves. Such methods include laser tracker measurements [12,13] , laser interferometers [14][15][16] and 1D spherical error array measurements [17] . The laser interferometer measurement method is widely used due to the advantages of measurement efficiency and it has become the main research direction on error compensation.…”

Due to the complex mechanism of the influence of Abbe error on spatial accuracy, the Abbe error accumulated in the traditional spatial accuracy model is hard to be identified and cannot be eliminated, which affects the modeling accuracy and restricts the effect of accuracy improvement. This paper presents a data-driven spatial accuracy modeling method for machine tool under the influence of Abbe error, using a three-axis coupling measurement optical path to directly measure the comprehensive spatial accuracy data of machine tool containing Abbe error. In addition, in order to effectively identify the Abbe error in the comprehensive spatial accuracy, the Abbe error quantization function is established to eliminate the Abbe error in the spatial accuracy data of machine tool by analyzing its formation mechanism in the measurement process. Further, aiming at the problem of small data samples after eliminating Abbe error, the data samples are extended based on the degradation mechanism of machine tool spatial accuracy at different coordinate positions, and a high-precision spatial error model for machine tool is given. Finally, the experiment is conducted on a three-axis CNC machine tool with the model accuracy of over 95%, and the example application verification shows that the developed model scheme is feasible and effective.

“…However, the above-mentioned methods have different kinds of shortcomings. For instance, the laser interferometer measurement system, which is widely used in the field of ultraprecision measurement and ultra-precision machine tools, can achieve very high resolution [6]. More sensitive temperature, humidity and other sensors are integrated into the system to achieve more stable measurement of nanoscale measurement tasks.…”

Polar microstructure is the 10-μm aperiodic surface pattern which is designed to achieve nanoscale resolution and applied in the precision measurement area. In this paper, an investigation of the major factors of a novel template-matching based precision measurement method which integrates with polar microstructure and computer vision (IPMCV) is proposed. In order to optimize the measurement performance of IPMCV method, three crucial factors are determined according to the template-matching method: the size of global image, the size of template image and the number of interpolated sub-pixels. According to the measurement accuracy, the size of global image has little influence on the position error, but significantly influences the standard deviation value of the error gradually. Besides, the size of template image helps to significantly improve the measurement accuracy, and the increase of the number of interpolated sub-pixels increases the measurement accuracy within a certain range but has no effect afterwards. The experimental results have great significance on the determination and optimization of parameters for IPMCV method to achieve a better measurement performance.
