“…The processing technology for mandrel parts mainly encompasses traditional precision turning [9], traditional precision grinding [10], manual polishing [11], and timecontrolled grinding technology [12][13][14][15]. Traditional precision turning and grinding involve using a lathe or grinder to process the mandrel, with the final surface accuracy depending on the precision of the machine tool employed.…”

The mandrel parts, as the essential component of the aerostatic spindle, play a pivotal role in determining the performance of both the spindle and ultra-precision machine tools. However, the stringent precision machining requirements of these parts pose significant challenges to machining technology. In this paper, an integrated process method combining in-situ measurement and machining specifically tailored for the mandrel of the aerostatic spindle is introduced. Using this method, spindle radial error, machine coaxiality error, and slide linear motion error can be accurately separated from the original measurement data, enabling the precise reconstruction of the mandrel's cylindrical shape. Based on the reconstruction results and time-controlled grinding technology, the cylindricity of the spindle's mandrel ultimately achieved 0.5 µm. The readings from a commercial roundness meter is used to validate the accuracy of in-situ measurements. Overall, this integrated process offers a novel approach for high-precision machining of mandrel parts, demonstrating that high-precision machining can be achieved even with low-precision machine tools.

“…[7] found that the effect of a lower-order frequency is hardly experienced by a milling machine even at lower cutting depths, as the machine governs stability, resulting in a completely different behavior. To verify the influence of natural frequencies and structural characteristics on the processing quality, [8,9] implemented FEA to extract the static and dynamic features of the machine. An AIM polynomial was used to establish a prediction model for the quality processing of a five-axis machine.…”

In order to enhance the accuracy and productivity of CNC machine tools, Finite Element Method (FEM) is utilized for analyzing machining operations and machine tool structures. Through this approach, it becomes possible to assess and reduce machining errors, thereby improving the precision of machined parts. Additionally, by subjecting machine tool components to analysis of stress and deformations under real operating conditions, the overall performance and lifespan of the machine tool structures can be augmented. This study provides a comprehensive review of recent published papers focusing on the implementation of finite element methods for the analysis and optimization of CNC machine tool operations and structures. In this study, a virtual model of the Goodway CNC turning machine was used to study the machine's behavior. The first three vibrational modes analyzed through a modal analysis were 108.2Hz, 133.4Hz, and 191.7Hz, which were experimentally validated using modal tests. The design precision was supported using the harmonic response. For an applied external load of 500N on the head chuck, the tool turret's transient response was established through transient analysis at 0.4s. However, after the static analysis, the maximum deformation of the machine at the same external applied load on the tool turret was upheld at 7.6µm. The spatial position analysis rectified the modal performance of the machine at a variety of set working positions. As the principal cause of rigidity originates from the base of the machine, three sets of ground support combinations were claimed to test the machine's rigidity. After the topology optimization analysis was achieved, a better-optimized version of the design is suggested. The old and new models were compared, and an increase of 1.5% in the first three modal frequencies was observed.
