  • A new tooling system for corrective finishing of narrow cylindrical optics

    A Pratap, CK Jain, A Beaucamp

    Journal of the European Optical Society-Rapid Publications 21 (2), 37 21 ( 2 )  2025.08

    ISSN  1990-2573

    　View Summary

    Finishing of complex surfaces needs simultaneous movement of multiple axes and precessing the tool on the surface in a desired tool path. For finishing narrow internal surfaces, the conventional spherical or flat end tools are difficult to precess inside the geometry. Therefore, this work presents a new tooling system for grinding narrow channels on tungsten carbide surface, to be used in optical applications. A thin wheel type finishing wheel and related jig is designed to use on an ultra-precision finishing machine. Finishing using the newly developed wheel type tool with different grade shape adaptive grinding pads could generate excellent surface finish within Ra = 3 nm. Form correction capability of the developed tooling system was also verified where the form error of the channel could be reduced to ∼7 lm P-V from an initial error of ∼42 lm P-V, in 5 h of processing time.

  • Erosion mechanism and surface quality in airflow-driven abrasive microchannel fabrication

    M Yu, Y Han, L Jiang, L Qian, A Beaucamp

    International Journal of Mechanical Sciences 294, 110263 294 2025.05

    ISSN  00207403

    　View Summary

    This paper investigates the erosion mechanism and surface quality of microchannel fabrication using airflow-driven suspended abrasives under mask constraints, a process known as submerged pulsating air jet polishing (SPAJP) with a mask. A multiphase Computational Fluid Dynamics (CFD) model is developed to simulate this process and analyze the evolution of jet morphology. An erosion mechanism for microchannel topography at various angles under mask constraints is proposed. It is believed that the erosion topography is primarily influenced by the competitive and synergistic interactions between primary particles entrained in the jet and secondary particles rebounding from the mask sidewalls. Additionally, secondary particles rebounding from the bottom surface play a significant role in edge erosion. An experimental study is conducted to examine the impact of several key factors on microchannel surface quality and the evolution of microstructural topography at different angles. The results show that the integrity of the mask has a significant impact on the surface quality of the fabricated microchannels, while the processing direction affects the uniformity of the removal depth, primarily due to the concentration gradient caused by the precipitation of suspended abrasive particles. The jet angle is found to have a considerable impact on the erosion topography, with the profile evolving from an asymmetric W-type to a biased Gaussian-like shape, and finally to a symmetric Gaussian-like form as the angle increases from 30° to 90°, which aligns with the proposed erosion mechanism. Moreover, a method for predicting surface topography in mask-fabricated microchannels, accounting for edge erosion, is proposed and validated through experimental and simulated comparisons. The results emphasize the critical role of edge erosion in shaping and predicting the topography of mask-fabricated microchannels. This research presents a highly promising, cost-effective, and environmentally friendly processing method and foundation for the high-quality fabrication of microchannels and other microstructures.

  • Faster surface finishing with shape adaptive grinding plus ceria

    A Pratap, K Copson, A Beaucamp

    Journal of Materials Processing Technology 336, 118704 336 2025.02

    ISSN  09240136

    　View Summary

    Shape adaptive grinding (SAG) is a well-established approach to obtain optical smooth quality on hard ceramic and metallic surfaces. However, the process has been limited to low material removal rate (MRR) when already smooth surfaces are processed using SAG pads. In this work, shape adaptive grinding plus ceria (SAG+) is put forward as an effective approach to increase the MRR, whereby ceria is used as polishing slurry and enables softening of glass/glass-ceramic surfaces through chemical reaction and enhances subsequent material removal through mechanical action of the SAG pad. A macroscopic material removal model is established for SAG+ process on BK7 glass where the effect of ceria on the surface hardness correlates well with the material removal rate. Experiments were performed on BK7 glass with different grades of resin bonded diamond SAG tools to benchmark performance against the standard SAG process. It was observed that the material removal rate increased by 3.5–10 times for SAG+ when all other conditions remain the same. It was also determined that removal rate increases most drastically when the abrasive grit of SAG pad and ceria slurry are of comparable size. Lapped Zerodur™ samples were also processed to check the applicability in pre-polishing of rough glass-ceramic surfaces. A reduction of almost 50 % could be obtained in processing time when using the SAG+ process.

  • Optimization of segment topology and surface form for efficient illumination with freeform lens arrays

    A Sasaki, O Kirino, K Watanabe, A Beaucamp

    CIRP Annals 74 (1), 179-183 74 ( 1 ) 179 - 183 2025.01

    ISSN  00078506

    　View Summary

    Freeform optics allow holistic system design in both fields of imaging and illumination. In combination with lens arrays, they enable advanced applications such as aberration free imaging and beam redistribution from multiple irradiation sources. This paper describes an automated design method for freeform optical arrays in both tangential and normal directions. Optimizing the tangential layout of segments increases the solid angle of light collection and thus improves energy efficiency. Surface shapes are then computed by an iterative construction method based on Fermat's principle and Snell's law. Complex illumination with up-to 85% light collection is demonstrated experimentally.

  • Ultrasonic assisted abrasive nano-blasting

    A Pratap, W Zhu, M Yuka, A Beaucamp

    CIRP Annals 74 (1), 459-463 74 ( 1 ) 459 - 463 2025.01

    ISSN  00078506

    　View Summary

    This research introduces abrasive nano-blasting using fine abrasive particles. Fine abrasive particles are difficult to use in abrasive blasting due to tendency of forming agglomerates caused by prevalent surface forces. The pressure gradient and streaming effect of ultrasonic vibration is utilized to break the abrasive agglomerates before impacting the workpiece for polishing. It could be observed through simulations that the pressure gradient to overcome the adhesive forces and breaking the agglomerates can be theoretically achieved. Polishing experiments revealed that acoustic streaming inside the ultrasonic cavity also improved uniform surface generation with up to 67 % reduction in surface roughness Sa.

    　View Summary

    In this study, an abrasive grain homogenization method was studied and implemented. The method is based on the generation of an acoustic streaming flow inside a cylindrical cavity by ultrasonic vibration. It can be applied before injecting the disaggregated abrasive grains in a nano-blasting nozzle that is impiging a workpiece.
    Experiments confirmed that the agglomeration of particles with a primary particle size larger than 2μm can be well broken down. In the case of particles with a primary diameter smaller than 2μm, some agglomerates remained while the rest of the agglomerates were broken up.
    The process was shown to allow blasting of surfaces at conditions near the boundary between particle deposition and material removal. When abrasive grains with a primary grain diameter of 2μm were used for processing glass, the surface roughness became noticeably smaller when ultrasonic vibration was applied, under most processing conditions.

  • Micro-bubble assisted abrasive waterjet polishing

    　View Summary

    In fluid jet polishing (FJP), a polishing liquid is pressurized as a jet and and impinges a surface. An improved system consisting of an ultrasonic transducer and acoustic lens mounted atop the FJP nozzle cavity was tested, which boosted material removal rates by up-to 1000%. However, it was not clear whether the removal boost was due to a micro-scale or macro-scale phenomenon.
    A study of micro-pit formation by collapsing micro-bubbles in the near wall region determined that micro-jetting and water hammer pressure do not seem to occur in UFJP, so the micro-scale hypothesis was ruled out.
    A study of workpiece vibrations found that significant shear forces exist at the workpiece surface when ultrasonic vibration is applied to the FJP beam. After theoretical confirmation of the correlation between macro-scale fluid displacement and shear force, the standard erosion model in FJP was modified by adding time-averaged vibration terms. The model and experiments were finally in good agreement.

  • Ultrasonic cavitation assisted fluid jet polishing

    　View Summary

    Fluid jet polishing is a versatile process used in super-fine finishing of complex optics and prosthetic joints. Its advantages include highly controllable sub-millimetre polishing footprints and absence of tool wear. But the very low material removal rate means that hard materials such as cemented carbides and super-alloys, used in optical surfaces and prosthetic joints, cannot be polished from a rough condition.
    In this research, we proposed a new method for adding finely controlled micro-bubbles into the slurry jet by ultrasonic cavitation. Acoustic and fluid dynamics simulation confirmed that under the right conditions, cavitation bubbles generated in the nozzle can reach the surface of the workpiece before collapsing. A prototype system was fabricated, and micro-bubbles could be observed at the nozzle outlet using a high-speed camera. Polishing experiments data then showed that micro-bubbles boost removal rate by up-to 380%, without causing any degradation of the surface finish.

  • 次世代高性能硬Ｘ線非球面望遠鏡の超平滑面創成

    　View Summary

    欧米の協力の下に日本が2015年度に打上げる硬Ｘ線望遠鏡と軟Ｘ線望遠鏡を搭載したＸ線天文衛星ASTRO-Hの開発は終了し、現在は打ち上げ前の種々のテストを行っている。高性能な硬Ｘ線望遠鏡を開発するには現状の円錐近似の反射鏡ではなく、正確な回転放物面と回転双曲面からなる反射鏡が必須であり、軽量化のためには超精密な非球面金型からレプリカ法で非球面反射鏡基板を製作する方法がベストである。
    従来は前加工のし易さからアルミニウム合金を超精密ダイヤモンド切削し、それに無電解ニッケルを成膜し、ダイヤモンド切削と研磨で非球面金型を製作する方法と合成石英を研削・研磨して非球面金型を製作する方法を研究開発して来た。しかし、日米欧の経済状態から次世代の硬Ｘ線望遠鏡にはより安価に非球面金型を製作する技術の開発が急務となった。特に、合成石英の非球面研磨では所用の形状を創成するのに年単位の時間が必要であった。
    そこで、本年度は、前加工が極めて容易なグラファイトを金型材料として採用し、非球面切削後に炭化珪素を化学気相成長させ、その表面をこの研究で開発したShape Adaptive Grinding (SAG)工具で研削する方法を見出した。この工具は研究室内で極めて容易に製作でき、工具寿命も10時間以上あり、表面粗さ0.4nm Ra以下の面を従来法に比べ１～2桁高能率な10～100mm3/minの除去速度で加工できることを見出した。液晶用ガラスをＸ線反射鏡基板として使う場合に使用できる非球面金型をこのSAG研削のみで製作できることが判明し、次世代の高性能硬Ｘ線非球面望遠鏡の新しい製作法として注目を浴びている。
    この研究により研究分担者は国際生産工学アカデミー(CIRP)より2015年8月にTaylor Medalを受賞することになった。
