Due to the device miniaturization, there is a growing need for micro-machining on silicon wafers. Compared with the thermal machining processes for micro-drilling (such as laser machining), mechanical micro-machining processes can avoid the generation of heat-affected-zone, recast layers, and silicon oxidation. Conventional mechanical micro-machining (CμM) of brittle materials generates a higher cutting force and severe quality issues (such as cracking and edge chipping). To address the quality issues, drilling with rotary ultrasonic micro-machining (RUμM) has been proposed and applied. There are no reported investigations on comparisons of micro-machining quality in CμM and RUμM. In this study, the effects of ultrasonic vibration, tool diameter, and feed rate on cutting force and edge chipping were investigated experimentally. To explain machined hole quality (edge chipping) and cutting force, effects on indentation depth were also investigated. We developed the mechanistic models to describe the relationships between input variables and single abrasive indentation depth for both CμM and RUμM processes.

The rotor-bearing test rig is set up to study the vibration of the rigid rotor supported by PAJBs with three types of O-rings mounted for different supply pressures.

The influence of the stiffness and damping of O-rings on the nonlinear dynamic characteristics of the systems is further studied by expanding the parameter range of the numerical simulation, and the relevant laws are summarized. The results demonstrate that both the stiffness and damping of O-rings have significant influence on the stability of the rotor-PAJB system. When the stiffness of O-rings is in the unstable stiffness interval, the stability of the rotor at high speeds will decrease. Meanwhile, larger damping produces better stability.

By focusing on the constrained bending capacity of guidewires in vascular procedures, the research delves into the surface microstructure design of flexible interventional guidewires to enhance their bending angles. This advancement facilitates smooth interventional procedures within limited workspaces. The research investigates how various structural size parameters of the surface microstructure affect the maximum bending capability of interventional guidewires. It encompasses the design and manufacture of four types of flexible interventional guidewires featuring rectangular, triangular, arc-shaped, and concave-pit-shaped microstructures. A theoretical model for guidewire bending angles is established, and through theoretical numerical analysis, the correlations between different microstructures, microstructural size parameters, and bending angles are elucidated. The study examines the bending characteristics of the four microstructured flexible interventional guidewires under tendon stretching displacement. Simulation analysis is employed to assess the influence of microstructural size parameters on the bending angles of the guidewires, confirming that guidewires with concave-pit-shaped microstructures can achieve greater bending angles, thereby enhancing their bending capabilities. An experimental setup is arranged to explore the bendable angles of the flexible interventional guidewires with the four types of microstructures. Furthermore, experiments on the interactive compliance between the microstructured flexible interventional guidewires and blood vessels are conducted to validate the guidewires’ deformation capabilities. The study affirms that the flexible interventional guidewire with concave-pit-shaped microstructures displays a greater bending angle. Specifically, the concave-pit-shaped microstructured flexible interventional guidewire, measuring 50 mm in length, can achieve a bending angle of 195° when subjected to a tendon stretching displacement of 4 mm, enabling successful interventions in intricate and narrow vascular networks like those encountered in heart/brain vasculature.</div></div>","PeriodicalId":54589,"journal":{"name":"Precision Engineering-Journal of the International Societies for Precision Engineering and Nanotechnology","volume":"93 ","pages":"Pages 70-86"},"PeriodicalIF":3.5,"publicationDate":"2025-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143287494","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Then, collision detection is performed on CNC machining through grading. In the first stage, the repeated projection method quickly eliminates long-distance non-intersecting collision detection. In the second stage, in order to further accurately detect, a hierarchical bounding box tree is constructed to divide the bounding boxes into layers and traverse the intersection states of each node layer by layer.

However, the inherent bandwidth limitations of the current slow slide servo technique lead to significant tracking errors, posing critical challenges to achieving high-efficiency and high-precision fabrication of these intricate surfaces. To address these challenges, this work proposes a novel data-driven surrogate model for tool trajectory modification that predicts servo axis tracking errors and adjusts the reference tool path prior to cutting operations, thereby enabling effective feedforward compensation. A two-dimensional convolutional neural network (2D-CNN) surrogate model is employed to capture the dynamic properties of tracking errors inherent in servo axes, with particular emphasis on the servo axis along the depth-of-cut direction. The predicted tracking errors serve as feedforward compensation terms for the initial reference trajectory, generating the modified diamond tool trajectory. Experimental validation on a commercial three-axis ultra-precision machine tool demonstrates the effectiveness and practical applicability of this trajectory modification method. Comparative results indicate that, with the assistance of the proposed modification method, the peak-to-valley (PV) error for segments of the tracked tool trajectory decreases from 1.29 μm to 0.59 μm, and the root-mean-square (RMS) error decreases from 373 nm to 138 nm; the PV error for the cross-sectional profiles of machined freeform surfaces decreases from 1.25 μm to 0.65 μm, and the RMS error decreases from 196 nm to 117 nm.</div></div>","PeriodicalId":54589,"journal":{"name":"Precision Engineering-Journal of the International Societies for Precision Engineering and Nanotechnology","volume":"93 ","pages":"Pages 46-57"},"PeriodicalIF":3.5,"publicationDate":"2024-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143286917","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It starts from the requirements on an already defined compliant structure, modeled as a two-port system, and leads to the design of the suspended body, that serves both as input and output port. The kinetostatics of the elastic suspension is described by resorting to the ellipse of elasticity theory, under the assumptions of linear deflections and linear elastic material. Then, the point compliance synthesis, based on spectral analysis, targets the field of displacements of the suspended body to define the points meeting the design requirements. The synthesis problem is formulated as a non-dimensional algebraic system that always admits real solutions.

Accurate temporally and spatially resolved MP temperature field measurement using this STWIP method requires a precise profiling of pixel-wise two-wavelength intensity ratio, which is highly dependent on optical alignment, and camera's spectral sensitivity, among other factors. Thus, it is essential to develop an accurate, robust, and fast transformation method for reliable and effective mapping of two-wavelength images acquired from the STWIP system. In this work we propose a Blob analysis-based MP guided Image Transformation (BMPIT) method as opposed to the typical feature detector descriptor-based image transformation approach like KAZE. The BMPIT's performance is assessed and compared with the KAZE in terms of efficiency, execution time, accuracy, and robustness. An experiment using a standard calibrated tungsten filament strip lamp is done to validate the effectiveness of BMPIT. Compared to the KAZE, the BMPIT successfully transformed 100 % of the MP images with higher accuracy and faster speed. It is also shown that the BMPIT is a robust technique for image transformation, unaffected by the image size, MP position, and surrounding noise. Moreover, experimental ground truth data collected using Type C thermocouples implanted into an Inconel-718 build plate are used to further validate the LPBF MP temperature estimation accuracy of BMPIT-aided STWIP. Unlike KAZE, temperature estimated by BMPIT agrees well (error &lt;5 %) with both the lamp and thermocouple experiments. BMPIT is an appealing alternative for online measurement due to its reduced execution time, it takes only one fifth of the time that KAZE takes to transform two-wavelength images. In addition, the BMPIT can be used to calculate MP width, which is validated by comparing with ex-situ characterization. It enables a high level of agreement (with an error less than 1.89 %) between MP images of two wavelengths. Overall, the BMPIT greatly improves STWIP image processing, allowing for measuring MP temperature and morphology more rapidly, accurately, and precisely. The developed BMPIT approach can be employed as part of a STWIP-feedback LPBF process control system to improve the quality of additively manufactured metal products.</div></div>","PeriodicalId":54589,"journal":{"name":"Precision Engineering-Journal of the International Societies for Precision Engineering and Nanotechnology","volume":"93 ","pages":"Pages 1-17"},"PeriodicalIF":3.5,"publicationDate":"2024-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143286916","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
