“…The usual static performance parameters of aerostatic bearings are the load carrying capacity and static stiffness, whereas the dynamic performances are usually evaluated in terms of rotordynamic stability and pneumatic hammer stability. The rotordynamic instabilities induced by low viscosity and crosscoupled behavior can be suppressed by reducing the bearing clearance-to-diameter ratio by an order of magnitude [28]. The stiffness and pneumatic hammer stabilities are two important but contradictory indices.…”

Fluid lubricated bearings have been widely adopted for supporting components of high-end equipments in the field of metrology, semi-conductor, aviation, strategic defense, ultra-precision manufacturing, medical treatment and power generations. These fields all involve extreme working conditions such as ultra-high moving precision, ultra-high rotation speed, ultra-heavy bearing load, ultra-high environmental temperature, high radiation and high vacuum, which present challenges for the design and optimization of reliable fluid lubricated bearings. Breakthrough of any related bottlenecks will promote the development course of high-end equipments. To further promote the advancement of high-end equipments, this paper reviews the design and optimization of fluid lubricated bearings operated with typical extreme working performances. Targeting on the realization of extreme working perfor mances, the current challenges, the current solutions, the underlying deficiencies and the promising developing directions regarding to the design and optimization of fluid lubricat ed bearings are systematically pointed out. This paper can provide guidance for choosing suitable fluid lubricated bearings and optimizing their structures based on required extremeworking performances.

“…Processes 2024, 12, x FOR PEER REVIEW 3 of 13 grinding conditions change, the optimal value of the fractional part of the speed ratio will change accordingly; but how to determine the optimal rotational speed ratio value while considering the other grinding conditions remains unclear. In previous works [44,45], we studied the vibration characteristics of the grinding wheel spindle and the surface formation mechanism under the spindle vibration in a parallel grinding process, and proposed a method using the reduced fraction of rotational speed ratio (not the fractional part of the decimal form) to predict the surface patterns. In this work, further analysis will be conducted to study how to optimize the grinding processes by using the reduced fraction.…”

Hard materials have found extensive applications in the fields of electronics, optics, and semiconductors. Parallel grinding is a common method for fabricating high-quality surfaces on hard materials with high efficiency. However, the surface generation mechanism has not been fully understood, resulting in a lack of an optimization approach for parallel grinding. In this study, the surface profile formation processes were analyzed under different grinding conditions. Then, a novel method was proposed to improve surface finish in parallel grinding, and grinding experiments were carried out to validate the proposed approach. It was found that the denominator (b) of the simplest form of the rotational speed ratio of the grinding wheel to the workpiece has a great influence on surface generation. The surface finish can be optimized without sacrificing the machining efficiency by slightly adjusting the rotational speeds of the wheel or the workpiece to make the value of b close to the ratio (p) of the wheel contact width to the cross-feed distance per workpiece revolution. Overall, this study provides a novel approach for optimizing the parallel grinding process, which can be applied to industrial applications.
