Ultra‐precision machining (UPM), one of the most advanced machining techniques that can produce exact components, significantly impacts the technological community. The significance of UPM attracts the attention of academic and industrial partners. As a result of the rapid development of UPM caused by technological advancement, it is necessary to revisit the current stages and evolution of UPM to sustain and advance this technology. The state of the art in UPM is first investigated systematically in this study by identifying the current four major UPM themes. The UPM thematic network is then built, along with a structural analysis of the network, to determine the interactions between each theme and the primary roles of theme members responsible for the interactions. Furthermore, the “bridge” role is assigned to the specific UPM theme content. On the other hand, Sentiment analysis is conducted to determine how the academic community at UPM feels about the themes for UPM research to focus on those themes with a need for more confidence. Considering the above findings, the future perspective of UPM and suggestions for its advancement are discussed and provided. This study provides a comprehensive understanding and the current state‐of‐the‐art review of UPM technology by a text mining technique to critically analyze its research content, as well as suggestions to enhance UPM development by focusing on its current challenges, thereby assisting academia and institutions in leveraging this technology to benefit society.This article is categorized under: Algorithmic Development > Text Mining Application Areas > Science and Technology Application Areas > Industry Specific Applications

Machine tool spindle stiffness is a leading technical indicatoraffecting cutting ability. However, the stiffness of the machine tool spindle with fluid bearings has not been studied thoroughly. This paper proposes a new methodology for the spindle stiffness with fluid bearing including definition of the spindle nose stiffness, experimental method and calculation method for this stiffness. A motorized spindle with hydrodynamic water-lubricated spiral groove bearings developed in our laboratory is selected as an object, a theoretical and experimental investigation on the spindle nose stiffness is conducted. The result shows that the proposed experimental method can be utilized to measure the nose stiffness of spindle with the fluid bearings, meanwhile, the spindle stiffness can be obtained by simultaneously solving the rotor dynamic model and the fluid bearing dynamic model. The fluid bearing spindle stiffness depends strongly on the rotary speed and the external load. We expect an improvement for the experimental device by introducing another load device to apply a perturbation load with an any angle to the external load on the spindle nose.

“…Small high-speed precision cylindrical roller objective uneven material, shape asymmetry, and other factors make its center main inertia axis and the axis of rotation there a certain deviation, resulting in the cylindrical roller work of dynamic unbalance [1,2]. The cylindrical roller with dynamic unbalance will generate periodic centrifugal force [3][4][5] when rotating at high speed, and the larger centrifugal force will change the force state of the cylindrical roller, intensifying the cylindrical roller's rotational slippage and spin sliding [6], accelerating the wear of the cylindrical roller surface, reducing the performance, working life and efficiency of rotating machinery [7].…”

In order to solve the problem of small high-speed precision cylindrical roller, which is difficult to drive and the surface is easily damaged when doing dynamic unbalance detection due to the small size and light mass of the roller, this paper proposes a new drive method, using air flotation non-destructive support instead of V-block or cylindrical surface of the roller and other lossy contact support and air flotation electric spindle combined with vacuum suction cup instead of belt friction drive; establish a mathematical model of cylindrical roller force to study the force of cylindrical roller in the air flotation sleeve during the drive, and through the force analysis, it is shown that under the condition that the structural parameters and material parameters of the drive remain unchanged, the start-up speed of the drive depends on the load-bearing capacity of the air film on the cylindrical roller; the mathematical model of the air film load-bearing capacity and the thickness of the air film is established to study the changing characteristics of the air film load-bearing capacity in the air flotation sleeve, and the correctness of the mathematical model is verified through numerical calculation combined with simulation analysis; the test platform of the drive device based on the non destructive detection of cylindrical roller dynamic unbalance is built to further verify the feasibility of high-speed non-destructive drive of cylindrical rollers and to create favorable conditions for the development of the non-destructive detection instrument for small mass cylindrical rollers dynamic unbalance.
