Previous studies have indicated that grinding parameters are key factors influencing surface integrity and wheel wear behavior in the machining of hard-brittle materials. Building on this understanding, an optimization strategy centered on the grinding ratio is proposed herein for the first time to achieve simultaneous improvement of workpiece surface quality and wheel lifespan. Initially, a correlation model between grinding parameters and the grinding ratio was established using multiple linear regression and analysis of variance, revealing the evolution of wheel wear behavior and workpiece surface integrity under different grinding ratio conditions. Furthermore, a multi-objective optimization model tailored for hemispherical resonator was formulated, and the non-dominated sorting genetic algorithm (NSGA-II) combined with the ideal distance method was employed to determine the optimal grinding parameters. Experimental results demonstrate that, following optimization, hemispherical resonator surface roughness can be maintained within 68.90–76.94 nm, representing an improvement of 21.62 %–37.05 % compared with conventional grinding parameters, while the fluctuation range decreased by 33.14 %. Moreover, under the same material removal volume, wheel wear was reduced by 16.07 %–35.14 %. The proposed grinding ratio–centered optimization framework provides a theoretical basis for achieving high-quality and stable machining of hard-brittle complex curved components while extending wheel lifespan.</div></div>","PeriodicalId":54589,"journal":{"name":"Precision Engineering-Journal of the International Societies for Precision Engineering and Nanotechnology","volume":"98 ","pages":"Pages 224-235"},"PeriodicalIF":3.7,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145790630","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}

Electrochemical trepanning (ECTr) is a specialized electrochemical machining (ECM) method offering advantages such as easily controllable flow fields and high machining flexibility. However, machining efficiency is limited by the widespread adoption of the single-blade machining mode in current ECTr. Therefore, this paper proposed a multi-electrode synchronized electrochemical trepanning (MES-ECTr) with rotational feeding method, and established a MES-ECTr with rotational feeding device to realize the synchronized machining of multiple inner twisted blades in a single feed operation. The parameters such as the layout, quantity and diameter of ball bearings in the rotational feeding module were optimized through fluid-structure interaction (FSI) simulation, and the reliability of the device were improved. Furthermore, to improve machining stability for multiple blades, a multi-channel electrolyte control (MC-EC) platform was established to monitor and regulate the electrolyte flow of multiple channels in real-time, thereby enhancing flow field uniformity. Finally, the MES-ECTr with rotational feeding experiments were conducted. Stable synchronized machining of three inner twisted blades was achieved at 18 V machining voltage and 1.5 mm/min feed rate, with excellent surface consistency and accuracy consistency. Compared to conventional single-blade mode, machining efficiency improved by 226 %, demonstrating the effectiveness of the designed MES-ECTr with rotational feeding system and its promising application prospects.</div></div>","PeriodicalId":54589,"journal":{"name":"Precision Engineering-Journal of the International Societies for Precision Engineering and Nanotechnology","volume":"98 ","pages":"Pages 206-223"},"PeriodicalIF":3.7,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145790631","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}
